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.

sounds which are normal ie. contactors will “Click” or snap
