Kenmore 153.32118 Problem, Possible Causes, Corrective Action, No Hot Water, High Operation Costs

PROBLEM

NO HOT WATER

INSUFFICIENT HOT WATER/ SLOW HOT WATER RECOVERY

POSSIBLE CAUSE(S)

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.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

CORRECTIVE ACTION

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

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

DRIP FROM TEMPERATURE & PRESSURE RELIEF VALVE (Warning: Do not plug or cap T&P discharge pipe.)

OTHER

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.Excessive water pressure

2.Thermal expansion

3.Non-functioning Temperature & Pressure Relief Valve

1.The water heater does not immediately start

2.The heat pump does not run in Efficiency mode.

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

1.Check water supply inlet pressure. If higher than 80 PSIG, install a pressure reducing valve (50-60 PSlG is the recommended

pressure.)

2.See "Closed System/Thermal Expansion" section

3.Replace the Temperature & PressureRelief Valve

1.When first started the water heater takes

about 8 minutes to complete a diagnostic routine

2.Contact a qualified person for service
