Troubleshooting Checklist

Before calling for service, check the following points to see if

the cause of trouble can be identified and corrected. Reviewing this checklist may eliminate the need of a service call and quickly restore hot water service.

BE SURE TO TURN OFF THE ELECTRICITY (ELECTRICAL DISCONNECT SWITCH) WHEN CHECKING EQUIPMENT.

Not Enough or No Hot Water

1.Be certain the electrical disconnect switch serving the water heater is in the ON position. The pilot toggle switch on the cabinet should be ON.

In some areas water heater electrical service may be limited by the power company. If the heater operates on a controlled circuit, heater recovery may be affected.

The optional manual override switches on the cabinet front may be turned off, de-energizing the elements.

2.Check the fuses.

The electrical disconnect switch usually contains fuses.

The water heater has fuses located behind the cabinet front door.

3.If the water was excessively hot, and is now cold, the ECO high limit switch may have activated.

•See the Temperature Regulation section of this manual for more information on how to reset the ECO high limit controls.

Repeated activation of the ECO high limit switch should be investigated by a Qualified Service Agent.

4.The storage capacity and/or recovery rate of the water heater may have been exceeded by a large demand for hot water.

Large demands require a recovery period to restore water temperature.

5.Cold incoming water temperature will lengthen the time required to heat water to the desired temperature.

If the heater was installed when incoming water temperature was warm, colder water creates the effect of less hot water.

7.Sediment or lime scale may be affecting water heater operation.

Water Is Too Hot

Refer to the TEMPERATURE REGULATION section of this

manual.

Water Heater Makes Strange Sounds

1.Sediment or lime scale accumulations on the elements causes sizzling and hissing noises when the heater is operating.

The sounds are normal, however, the tank bottom and elements should be cleaned.

2.Some of the electrical components of the water heater make sounds which are normal ie. contactors will “Click” or snap as the heater starts and stops.
