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 will also cause the
water to over heat.
