SECTION 7—TROUBLE SHOOTING GUIDE
Problem
Possible Cause and Solution
No hot water flow at tap.
Valve on old water pipe supplying water tank should be open,
faucet aerator or restrictor may be plugged with sediment.
High Pressure Limit switch . Repeat system purge operation
opens repeatedly
. Unit plumbed incorrectly, cold water on bottom of feed tank
connected to HPWH outlet
3. Defective circulating pump
4. Tank thermostat set too high
5. Defective tank thermostat
6. Inadequate water flow due to plugged water lines
Water on floor around the tank . Check plumbing joints and fittings for leaks
. Make sue HPWH is level
3. Check condensate drain line for obstruction
4. Inspect drip pan for obstruction
5. If leak continues after unit is turned off, there is an internal leak
requiring service
6. The leak may be from the water storage tank
Heat pump trips a house
. Circuit does not have adequate circuit breaker capacity
circuit breaker
. There is a short, or loose connection in field wiring
3. There is a short or loose connection in HPWH wiring
4. Check to be sure that dual resistance elements are not wired for
simultaneous operation. Total wattage must not exceed
5500 watts
Water is not being heated . Check tank top thermostat. A setting of 5º F. at the
thermostat should sufficiently allow for 0º F. at the tap
. A mixing/tempering valve in the house plumbing could be
mixing cold water with the hot. Close the HPWH cold water
inlet valve, and open a hot water faucet in the house. No
water should come out of the faucet. If it does, cold water is
coming from the mixing valve
Water is too hot
. Check the tank top thermostat and limit switch
. Check the tank lower thermostat and limit switch
3. Check the HPWH for proper response to the thermostat
Water is not being heated . Check to make sure unit is plugged in, turned on, and the circuit
at all
breaker/fuse is not tripped
. Check the tank top heating element, limit switch, and thermostat
Hot water runs out,
. Tank thermostats are set too low or are defective
(HPWH continues to run)
. Dip tube in tank is broken
3. More than appropriate water use for the tank size
4. The air filter or coil fins are clogged or dirty
5. The unit remains in defrost mode
