TROUBLESHOOTING CHART

PROBLEM POSSIBLE CAUSE(S) CORRECTIVE ACTION

NO HOT WATER 1. No power to the water heater (power

button not lit)

2. Unit in standby (power button RED)

3. Unit in Vacation mode

4. High temperature limit switch open

5. Hot water usage pattern exceeds the

capability of the water heater in

current mode

6. Non-functioning upper temperature

sensor

1. Check for blown fuse or tripped breaker.

Restore power to unit then press power

button.

2. Press the power button to turn the unit on

(power button GREEN)

3. Press Vacation Mode Button to exit Vaca-

tion mode and return to desired operating

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. Contact a qualified person for service

INSUFFICIENT HOT WATER/

SLOW HOT WATER

RECOVERY

1. Temperature set-point too low

2. Air filter dirty

3. Hot water usage pattern exceeds the

capability of the water heater in

current mode

4. Water connections to unit reversed

5. Heat lost through long run of exposed

pipe

6. Hot water leak at faucet or piping

7. Non-functioning heating element

8. Sediment or scale build up in tank

1. Increase set point temperature; see

“Adjusting the User Interface Module”

section

2. Clean air filter

3. Change to different mode or modify usage

patterns (For example if in Efficiency Mode

switch to Hybrid Mode)

4. Ensure the cold connection is at the bottom

and that the hot connection is at the top

5. Insulate exposed piping

6. Repair hot water leaks

7. Call qualified person for service

8. Drain and flush tank. Water conditioning

may be necessary to minimize build up

HIGH OPERATION COSTS 1. Temperature set-point too high

2. Air filter dirty

3. Electric mode selected

4. Water connections to unit reversed

5. Heat lost through long run of exposed

pipe

6. Hot water leak at faucet or piping

7. Sediment or scale build up in tank

1. Decrease set point temperature; see “Ad-

justing the User Interface Module”

2. Clean air filter

3. Change to Efficiency or Hybrid mode for

reduced energy costs

4. Ensure the cold connection is at the bottom

and that the hot connection is at the top

5. Insulate exposed piping

6. Repair hot water leaks

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

2. Thermal expansion

3. Non-functioning Temperature &

Pressure Relief Valve

1. Check water supply inlet pressure. If higher

than 80 PSIG, install a pressure reducing

valve (50-60 PSIG is the recommended

pressure.)

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
