TROUBLESHOOTING

The Pool Heater Is Not Running Or Stops Less Than 2 Minutes After
Starting Up
Heat pump control set to low. Raise temperature set point.
Desired water temperature is reached. Unit will automatically re-start when the water temperature
goes below the set point.
Main breaker is tripped. Reset it.
Pool pump is not running. Turn the pool pump on.
Filter is dirty restricting the water flow. Backwash and clean filter.
The Compressor Is Running But The Fan Is Not
If the unit was just installed and the compressor starts before you have programmed the desired temperature,
it is possible that the electrical hookup was made on the wrong side of the contactor (relay). Contact your
electrician.
The fan motor may be defective. Contact Waterco's service dept.
The Fan Is Running But Not The Compressor
The unit is in its 3 or 5 minutes time delay protection mode.
The unit is on defrost. The compressor will start again automatically a few minutes.
There Is Water Around The Unit
While your Watero pool heater is in the heating mode, a large quantity of warm and humid air passes over the
evaporator and causes condensation.
It is normal to see condensation dripping under the heater.
To verify that the water is really a water leak you will need to stop the heater and leave the pool pump
running for over 5 hours. If water is still coming out of your heater after this period you should call Waterco
for service.
