TROUBLESHOOTING CHART
PROBLEM POSSIBLE CAUSE(S) CORRECTIVE ACTION
NO HOT WATER 1. No power to the water heater (power
button not lit)
1. Check for blown fuse or tripped breaker.
Restore power to unit then press power
button.
2. Unit in standby (power button RED) 2. Press the power button to turn the unit on
(power button GREEN)
3. Unit in Vacation mode 3. Press Vacation Mode Button to exit Vaca­
tion mode and return to desired operating
mode.
4. High temperature limit switch open
5. Hot water usage pattern exceeds the
capability of the water heater in
current mode
4. Reset the high temperature limit switch;
see “Safety shut-off” section for more
information
5. Change to different mode or modify usage
patterns
6. Non-functioning upper temperature
sensor
6. Contact a qualified person for service
INSUFFICIENT HOT WATER/
SLOW HOT WATER
RECOVERY 1. Temperature set-point too low 1. Increase set point temperature; see
“Adjusting the User Interface Module”
section
2. Air filter dirty 2. Clean air filter
3. Hot water usage pattern exceeds the
capability of the water heater in
current mode
3. Change to different mode or modify usage
patterns (For example if in Efficiency Mode
switch to Hybrid Mode)
4. Water connections to unit reversed
5. Heat lost through long run of exposed
pipe
4. Ensure the cold connection is at the bottom
and that the hot connection is at the top
5. Insulate exposed piping
6. Hot water leak at faucet or piping 6. Repair hot water leaks
7. Non-functioning heating element 7. Call qualified person for service
8. Sediment or scale build up in tank 8. Drain and flush tank. Water conditioning
may be necessary to minimize build up
HIGH OPERATION COSTS 1. Temperature set-point too high 1. Decrease set point temperature; see “Ad­
justing the User Interface Module”
2. Air filter dirty 2. Clean air filter
3. Electric mode selected 3. Change to Efficiency or Hybrid mode for
reduced energy costs
4. Water connections to unit reversed 4. Ensure the cold connection is at the bottom
and that the hot connection is at the top
5. Heat lost through long run of exposed
pipe
5. Insulate exposed piping
6. Hot water leak at faucet or piping 6. Repair hot water leaks
7. Sediment or scale build up in tank 7. Drain and flush tank. Water conditioning
may be required to minimze build up
DRIP FROM TEMPERATURE &
PRESSURE RELIEF VALVE
(Warning: Do not plug or cap
T&P discharge pipe.)
1. Excessive water pressure 1. Check water supply inlet pressure. If higher
than 80 PSIG, install a pressure reducing
valve (50-60 PSIG is the recommended
pressure.)
2. Thermal expansion
3. Non-functioning Temperature &
Pressure Relief Valve
2. See “Closed System/Thermal Expansion”
section
3. Replace the Temperature & PressureRelief
Valve
OTHER 1. The water heater does not
immediately start
2. The heat pump does not run in
Efficiency mode.
1. When first started the water heater takes
about 8 minutes to complete a diagnostic
routine
2. Contact a qualified person for service
