These are the Top 10 Most Common Hot Tub Issues/Problems


Over the years, we have seen problems in these areas:
  1. Flow or Pressure Switch problems
  2. Leaks in water lines or jets
  3. Burned circuit board
  4. Ozonator check valves
  5. Water chemistry
  6. Clogged filters
  7. Tripped GFI breakers
  8. Heater failure
  9. Pump Seal Leaks
  10. Circulation pump failure
Most of these issues can be averted simply by having us out for an inspection and service once a year.  Contact Us for more information.

Flow or Pressure Switch problems

1. Flow switch's and pressure switch's are mechanical components with a limited life expectancy. Newer systems may run out of calibration or connections fail, causing hot tub to shut down.

Leaks in water lines or the tub's jets

2. Water chemistry is may cause this problem and fail due to high pH corrosion levels making the silicon break down.

Burned circuit board problems

3. A burned circuit board is typically the result of loose heater terminal connection screws.  Over time, the screws vibrate and loosen the connection to the heater. Heat then builds up and transferring to the circuit board causing failure.  Another possibility is from the pumps drawing heavy amps - check if the windings are tight and not corroded.

Ozonator valves

4. Sometimes the small ozonator check valve's fail and trips the GFI.  You may consider drying the ozonator with a hair dryer.  Take a look at the parts we can sell, service and install.

Water chemistry out of balance

5. Almost 100% of all problems are due to lack of maintaining proper water chemistry in the spa. There is no such thing as maintenance free hot tubs.  However, with proper instruction, hot tubs are quite easily maintained once you know how do this properly and a regular routine is set up and followed. Don't pay for costly repairs when a preventative maintenance program and inspections can do the trick.

Clogged filter

6. When a hot tub is not heating properly or is has poor jet pressure, more than likely it is that the filter is dirty and should be washed out or replaced.

Tripped breakers

7. The pump, hot tub heater, or the ozonator, may be causing the tripped GFI. Most are triggered by a water chemistry problems, (High pH) that has caused these devices to fail.

Heater not heating or failure

8. 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.  The heater is made of metal and it simply corrodes and stops working.  Also, pump seals, rubber seal and gaskets and anything else can corrode in high pH water.

Pump Leaks (Seal)

9. Poor water chemistry is almost always the result of a premature failed pump seal. The symptoms are a small puddle of water around the equipment area and if unchecked could cause the electrical motor to short out from water spraying into the windings of the motor.

Complete circulation pump failure

10. All modern hot tubs have a 24/7 circulation pump. Water chemistry problems coupled with pump seal failure is a common problem with low pH, as previously explained with the heater failure. A simple inspection can catch this problem early before complete failure occurs with the hot tub water entering the electrical motor side of the pump, tripping the GFI and shutting the hot tub down.
