Spa Repair – 10 Most Common Problems With A Hot Tub

These are the 10 most frequent problems with a spa, hot tub, Jacuzzi or swimming pool that we have found.

1. Water chemistry

This is mother of all spa problems. 99% of all problems arise due to lack of maintaining proper water chemistry in your spa. We would not be in business as a spa and hot tub repair company if the proper water chemistry was maintained by spa owners.
We understand that spa sales men happily will tell you about the maintenance free spa or hot tub, or that they will tell you have easy they are to maintain. Well….. there is no such thing as maintenance free spa. However, with proper instruction a spa or hot tub are quite easy to maintain. But again, it has to be done.

Again and again we find that spa owners rather pay for costly repairs than pay for less costly preventative service programs.

2. Heater failure

Most heater failures are due to low ph in the water. Any ph under 7.0 for an extended amount of time will corrode the heating element to the point of failure. This will typically manifest as a tripped GFCI breaker and the results are mostly to replace the heating element or heater

3. Circulation pump failure

Many modern spas and hot tubs have a 24/7 circulation pump. Water chemistry problems coupled with pump seal failure is a common problem

4. Flow or pressure switch problem

Both a flow switch or a pressure switch are mechanical components with a limit life cycle.

5. Burned circuit board

Very costly repair. A burned circuit board is typically the result of loose heater terminal connection screws. After a few years, those screws tend to vibrate and loosen up the connection to the heater. This results in heat building up and transferring to the circuit board. That in turn can result in relay or contactor failure on the board.

6. Mice or rats

Still very common. Mice get in and eat on wires and hoses.

7. Clogged filters

The first thing we ask a home owner that calls in saying “my spa is not heating” is, “Did you clean your filters lately?”. That takes care of 90% of those problems.

8. Tripped GFCI breakers

Many things can result in a tripped GFCI breaker. Spa pump, Hot tub heater, ozonator and many more

9. Pump seal leaks

Poor water chemistry is almost always the result of a failed pump seal. The symptoms are a small puddle of water around the equipment area

10. Ozonator check valves

The small ozonator check valve fail and as a result water travels into the ozonator and trips the GFCI. Sometimes the ozonator can be dried with a hair drier, and at other times it would have to be replaced.
