Troubleshooting Your Spa
Water Gets Too Hot
Checking Thermostat and Heater Contactor:
Find the heater contactor in the control box (see picture below).
If it is not arced/welded shut and moves up and down freely, then the thermostat needs to be replaced. Thermostats are located in one of two places on a spa, either on the top of the spa (spa sides), or in a control box where the equipment is. See "thermostats" in Parts section. Replace the contactor if it was arced/welded shut. See "contactors" in Parts section. In some cases both of these will need to be replaced.
NOTE: Contactors arc or weld themselves shut due to "chattering" caused by:
|
 |
Low water level in spa
|
|
 |
Pressure switch out of adjustment
|
|
 |
Clogged or old filter
|
|
 |
Solid state thermostats
|
ONE MORE NOTE: Leaving your jets (jet pump) on for a long period of time may also cause the water to over heat.
