Replacing Your Hot Tub Circuit Board

Posted by

Most modern spas have circuit boards located inside the equipment area, commonly referred to as the “spa pack”. The spa pack is essentially the brain of your spa. If you find you need to replace the circuit board, it is very important to make sure you replace it with the correct board.

Many boards look identical; however their software may be different. Following these very important tips will help guarantee that when your new circuit board arrives it will work great.

IMPORTANT: Many circuit boards look alike, but may not work in your spa. DO NOT order a replacement circuit board based on appearance. Circuit boards must be identified by a part number and/or chip number. Read below how to identify your chip number.

Do You Need to Replace Your Circuit Board?

Depending on what’s wrong with your spa, different possibilities may exist causing the malfunction. It’s very important to identify the correct problem so you don’t waste money replacing parts that don’t need to be replaced. To get started, remove the cover on your spa pack.

Troubleshooting Tips:

  • A good indicator that your circuit board may be bad is if you are not receiving power to an important piece of equipment such as the pump, blower, heater, etc.
  • Checking voltage on the board will allow you to determine whether this is where you are losing power.
  • If you look at the circuit board itself, there may be melted components, or burn marks.

If you are unsure that your circuit board is the issue, it is best to seek the help of a professional spa technician.

Replacing Your Circuit Board

There are a number of companies that make hot tub circuit boards, and each may display the replacement information you need in a slightly different manner.

The information below will cover 3 of the most common brands, and will help you identify which replacement is correct for your spa:

Replacing your Circuit Board by Chip Number PDF

Balboa

Balboa spa packs have been used by many different spa manufacturers for years and are one of the most common. When replacing a Balboa board, you will need to find the “chip number”.

  • The chip number is an alphanumeric number that you will find printed on a white label placed on a black chip on the board itself.
  • Almost every chip number will end in a revision number. Examples are “R1A”, “R1B”, “REV. B’ or a similar combination.
  • The chip number defines the software used between the topside control and circuit board, and will guarantee that the topside control and circuit board will work together.

Balboa 1 (3)
Balboa 2 (3)
Balboa 3 (3)

HydroQuip

HydroQuip, another circuit board industry leader, has made identifying the proper replacement board very easy. Each one of their boards has a part number on a large white label placed directly onto the circuit board. To properly identify the correct HydroQuip board, simply match the part number on the label.
HydroQuip (2)

Gecko

To properly identify the correct replacement for a Gecko circuit board, you will need the “Model” and “Options” numbers. The Model and Options numbers are a series of alphanumeric numbers located on a label on the outside of your spa pack. Using these numbers to identify the correct board will guarantee a proper fit and operation.
Gecko (3)

If you have a circuit board made by a company not listed in this article, it is a good idea to get help from a professional. Getting the correct replacement board is important. Ordering a circuit board based on looks alone could end up being an expensive and time consuming mistake.

Finding Your Replacement

Once you have found your chip or part number, enter it in the search box. Your replacement board should display in the results.

If a corresponding board does not display, send an email to Support@spadepot.com and a technician will happily find the correct circuit board for you!

Installation

Once you receive the correct replacement board, it’s time to install it. Here are a few very important tips to keep in mind when installing your new circuit board:

  • Always make sure the circuit breaker is off and the spa is unplugged before attempting any hot tub repairs.
  • Take lots of photos of the old circuit board, paying special attention to where each wire is attached to the board, with a camera or your cell phone before you remove it. This will take the guesswork out of attaching all wires back to their proper location.
  • Be very careful when handling the new circuit board. Most boards have a number of components soldered to them. Knocking one of them off can destroy the entire board.
  • Using needle-nose pliers to remove the wires from the old board and to attach the wires to the new board will lessen the risk of damaging the wires.
  • Make sure when installing your new circuit board that the jumpers and switchbanks are matched to the circuit board you are replacing to ensure proper hot tub function. Jumpers are small and can be hard to see, so make sure to take your time and find every jumper.

Switchbank & Jumper

Safety First!

Electrical work around water can be especially dangerous. Make sure that when you’re replacing a circuit board (or any other electrical component) that the power is completely disconnected.

If you do not feel confident replacing the circuit board yourself, seek the help of a hot tub technician or licensed electrician.

  1. I found it a good idea to take a digital photo of the circuit board and copy it into publisher or MS Word and identify the orientation and components, installation/removal procedures, C.B. serial numbers and software number codes, etc. This is especially important if you are configuring the C.B. for either 120 VAC or 220 VAC operation. Note the positions of the DIP switches as well.

    Unfortunately shutting off the power will not prevent a lightening strike from destroying the board. It is powerful enough to jump the wires and fry anything and everything.
    Replacing the spa pack may be less expensive than replacing just the board. If you would like to send photos of the equipment, we would be happy to quote you on the cost. We can usually supply these parts for the best price around. If you can include a photo of the board too we can quote you on a price for just the board. Sundance boards are usually pretty expensive and many are proprietary.
    You can email photos to: Support@SpaDepot.com
    I hope this is helpful. Please let me know if you have any additional questions.

  9. I have ordered a circuit board for our Sweetwater Spa. I am concerned that the real problem may be the heater or the heater element. I have tried testing the ohm resistance and get a reading of 12.5 with my tester set at 200. Do you have any idea if that is enough resistance?
    Ray

    Like

  10. Hi Ray,
    Thank you for checking with us. Having a resistance of 12.5 could mean that the element is fine. Normal resistance for hot tub heater elements is between 10-15 ohms. The best way to determine if the element is working properly, is by testing the voltage going to the element when the tub should be heating. As long as you have verified that you are getting anywhere from 220V-250V from your house into the hot tub, test both leads going to the element. If that is the same as the incoming voltage, or very close to it, you have a bad heater element. If the voltage shows zero, there is a problem with the circuit board.

  11. I have a 2000 Sundance Altimar. I shut the power off to clean the filter and when I turned it back on the circulation pump was not working. Everything else works still. I did a continuity test on the connector that the circ pump wires go to (TB2) and got no sound. Something on the meter was saying 1.8 but can’t remember if it was volts or ohms or what. The tab to open one of the connector holes broke off and now I can not get the wire back in. The circ pump is only a month or 2 old. Can I get the TB2 connector replaced and can the power supply be repaired to the circ pump connector? Thanks.

  12. Hi Gary,
    Thank you for checking with us! The best way to determine the source of the problem is to test the voltage going to the pump, instead of testing for continuity. If the right voltage is being sent to the pump and the pump is not running, the pump is bad and will need to be replaced. If there is no power going to the pump, the problem is with the circuit board. I am happy to take a look at the connection and let you know if it can be repaired or replaced. Please email a couple photos of the broken connection, and a photo of the whole circuit board to help@SpaDepot.com, attention Mark. Once I receive the photos I will get back to you quickly.

  13. I have a 2005 Hydro spa Mark III. I just replaced the topside unit with the Balboa controller said to replace the old unit. I filled the tub as usual and when I turned it on after the start up routine My circulation pump started to cycle as if the pressure switch went bad. I have a Balboa HS200M7 which does not have a pressure switch. Could I possibly have a circuit board problem, and need to replace that as well?

    Like

  14. Hi Gary,
    Thank you for checking with us! I wouldn’t suspect the circuit board yet. Although your system doesn’t have a pressure switch, it does have two sensors that detect water flow. The first thing to try is to remove your filter and try running the spa without the filter cartridge installed. If you find that the flow error goes away, replacing your filter cartridge will take care of the problem.
    If removing the filters does not help, the next thing to do is to replace the sensors. We have them available here:
    http://www.spadepot.com/shop/Hi-LimitTemp-Sensor-Assembly-for-Balboa-M-7-Systems-32016-P9700C704.aspx
    If you replace the sensors and you’re still getting the error, the problem is in the circuit board and it will need to be replaced.
    Hope this helps!

  16. Hi Mike,
    Thank you for checking with us! I would make sure that both the 20 amp and 30 amp breakers are both on. If one is on and one is off, it could cause a problem like this. If both of the circuit breakers are on, the problem is likely a fuse or a transformer. The lights on the board don’t really help us in this situation. They’re saying there is a problem, and you have already identified that the problem is no power.
    Remove the fuses and check them with an ohm meter. If you find a bad one, replacing it should take care of the problem. If you do not find a bad fuse, you will likely need to replace the circuit board.
    Hope this helps.

  18. Hi us4raddants,
    Thank you for checking with us! The problem you are experiencing sounds like it may be a connectivity issue.
    Try disconnecting the topside controller, and spritzing the connector on the circuit board and topside with some electrical contact cleaner. Allow that to dry for about an hour, then plug and unplug the topside from the circuit board about 10 times.
    This will polish the pins on the connector to ensure good connectivity.At this point, you should be able to plug the topside in and and be good to go. If the problem persists please feel free to give our technical department a call:

  21. Hi Eric,
    Thank you for checking with us. Usually a tech would recommend replacing the circuit board at this point, but I do not typically see circuit boards causing a spa to heat over the set temp. Even though you just replaced the sensors, the new sensors or the connection on the circuit board could be causing the problem. I recommend unplugging them from the board and plugging them back in 6-8 times. That will help clean off the connection. If the problem is being cause by corrosion or dirt built up on the connection point, unplugging them and plugging them back in a number of times will clean them off. If that does not help, I recommend contacting the company you purchased the sensors from. It would be a good idea to try replacing them again prior to replacing the circuit board. If the new replacement sensors do not fix the problem, the problem is definitely in the board itself. Hope this helps!

  22. Hi Dermott,
    Thank you for checking with us. That would usually only happen with a dirty or loose connection. If the topside control was plugged in firmly, the board could have had a problem with it in the first place. As long as there is no tension on the new topside cord when it’s plugged in, a new board and topside should plug together firmly and prevent this from happening again. I hope this helps, and thanks again for checking with us.

    Like

  24. Hi Joe,
    Thank you for checking with us. The copper wires you’re referring to are bonding wires that typically bond the frame of your motors to the frame of the spa pack. Those will not have any effect on whether the hot tub runs or not. If you’re not comfortable testing live electricity, it is best to hire a spa technician to find the problem. If you are comfortable testing electricity, make sure you’re getting the right voltage coming from the house. If you’re getting the proper voltage into the spa pack, the problem is either going to be a blown fuse, or the transformer. If you have a multi-meter, you can test the fuses to verify which one needs to be replaced. If all the fuses are intact, the problem is likely the transformer. I hope this helps!

  25. I have a 1999 Blue Ridge Spa that we purchased new. In the past 18 months I have replaced both the heater and the circulation pump (they are separate). Today I notice that the breaker had tripped. I flipped it back on and the high-speed pump immediately came on and smoke started coming out of the spa pack. The board is burnt. I am assuming that the board has gone bad and I need to replace it or the spa pack. The shell and plumbing of the spa are in great condition. The only thing left to replace is the blower and spa pack so I am tempted to keep fixing it. Is there anything that could have caused the spa pack to burn up or is it just bad from old age. I had to kill the breaker manually. I’m a bit surprised that it kept running and none of the breakers tripped or fuses in the spa pack burnt out.

    Like

  26. Hi Denny,
    Thank you for checking with us. Given the age of the hot tub, it is likely due to old age that the board burned up. The heater and the high speed pump are the two things on your spa that pull the most power though the system. Over time that can weaken the electrical termination points. The fact that it was smoking and it did not trip the breaker does not mean your breaker or electrical run are bad. The GFCI will only trip if there is a ground fault, and any non-GFCI breaker in the electrical run will only trip if excessive amps are being pulled by the hot tub. I would still recommend having the electrical run inspected by a qualified electrician.
    If you would like our recommendation for which replacement spa pack you need, please email photos of the equipment in the hot tub to help@SpaDepot.com .

    Like

  30. Hi Jean,
    If the spa is heating and the only problem is that the spa overheats, the burn on the heater relay may have nothing to do with your current problem. Typically a burn on a heater relay would prevent the heater from working. If your heater is working, the overheating is either caused by the temp sensor (even though you just replaced it) or the circuit board itself. You might try replacing the temp sensor again to see if it solves the problem. If it doesn’t, you will need to replace the circuit board.
    Hope this helps.

    Thank you for checking with us. The likely cause of this problem is the temperature sensor. First, locate where the sensor plugs into the circuit board, then unplug it and plug it back in a few times. A dirty or slightly corroded connection could cause the problem, and unplugging the sensor and plugging it back in a few times will clean it off. If that does not help, I recommend replacing the temp sensor.

  34. Hi Ryan,
    Any indication of burning on your circuit board is due to an increase in resistance, typically caused by corrosion or poor connections. The damaged circuit board could be causing the topside not to work, but without a new circuit board to test the topside, its tough to isolate whether the topside you have is good or bad.

  39. Hi I hope you can point me in the right direction to help me get my hot tub back in action. Some quick facts, this is my first season with a used hot tub that was previously indoors, and i have it now outdoors. Its a bit old- 12 years but looked in great shape. First problem was cracked nut which i have fixed, but then trouble with the breakers has me stuck. First it tripped once, the next day, 2x, the day after, constantly tripping. Went online to see what to do and eventually disconnected each part separately to see what was causing trip. Stopped tripping when i disconnected the heater wires from the heat tube. Then I saw the test to see whether it is my heater or the circuit board. Not sure if i did this right but when powered up i got zero reading on a reader from the terminals and wires to heater. I did this without the heater being hooked up to the wires though- just the two wires loose- not sure if this matters. Looking at the heater core, it has no crust, rust or buildup, but some minor scratches. Did an Ohm test on it and got 14.6 on it consistently. Not sure whether to replace board or heater at this point. I did break one of the metal pins that connects the heater wires to the heater core pipe when opening it up, so I’m going to have to replace the heater core anyways. Was thinking to get the new heater core, hook it up and see before i buy a new board, but before i do: I don’t understand how my board or heater would suddenly start tripping the breaker out of the blue when it was working, the heater was working (but slow to heat) etc. Also, I was running the tub without the heater for a bit, and everything else, the jets, lights, control panel, etc were all working fine, so I’m confused that if its a bad board, why would all these things be working well- how can i be certain i need a new board? Also- replacing a new board- i tried pulling some of the wires that are there and didn’t want to pull too hard- are they sodered on or are they supponsed to be pulled by hand? If i have to go that route it would be helpful to know.. Anyhoo, some clarity on what you would do in my situation would be great….

  40. Hi Jim,
    In your case, I would recommend replacing the heater element first, as it definitely needs to be replaced due to the damage. I’ll also note here that in 90% of cases where the breaker trips, there is a short to ground on the heater element that is causing the breaker to trip. This is supported by the fact that when you disconnected the heater element, the tub ran properly (except it wouldn’t heat). Please replace the element and let us know if you continue to experience difficulties.

  46. Hi Robert,
    The symptoms you’re describing are indicative of a bad spa control unit. Intex integrates the pump, heater and electronics into the “tower,” and the only solution they have is to replace that component. That component is proprietary to Intex, and is available from their customer support center. Once you replace the control system, you should be back up and running.
    Thanks,

  47. Gents, I have a problem with my Balboa spa pack. When I turn the circuit breaker on the top side control does not come on but the pumps start working speratickly. If I unplug the topside controls the spa acts as if I just turn both pumps on and seems to work fine on its own. Is the circuit board bad or is it the top side controls?
    Thanks
    Eric

  48. Hi Eric,
    Thanks for reaching out!What you are experiencing sounds like a topside issue. Most Balboa circuit boards have enough programming on them to operate the tub through filtration and heating up to 80°. Replacing the topside controller would be the best place to start.
    If you need help finding the correct replacement, one of our hot tub technicians will be glad to help!
