BEFORE YOU CALL FOR SERVICE
_-----------------------------WARNING
TO GUARD AGAINST SEVERE BURNS OR POSSIBLE FATAL ELECTRICAL SHOCK,
BE SURE TO TURN OFF ELECTRICAL POWER TO THE WATER HEATER BEFORE REMOVING ANY PANELS.
HELPFUL HINTS CHECKLIST
If your water heater fails to work right, make the following easy checks. Often, you will find what’s wrong yourself and you won’t
have to call and wait for service and hot water. If you do not find what’s wrong when making the checks, then call for service.
PLEASE READ THE WARRANTY NOTES ON PAGE 16.
A. NOT ENOUGH OR NO HOT WATER
1. Used more hot water than the water heater holds, or faster than the water heater can heat the water.
2. Hot water wasted through leaking or partially open faucet.
3. If the water heater is newly installed, check the Installation Steps to be sure it’s installed correctly
(THIS IS A 240V WATER HEATER AND MUST BE WIRED TO A 240V SUPPLY).
4. Make sure the electrical supply is turned on and that the cold water supply valve is fully open.
5. Check for a blown fuse or popped circuit breaker (circuit breakers weaken with age and may not handle the rated load).
6. During winter months, the colder supply water takes longer to heat.
7. The temperature limit switch (Page 10) may have opened the circuit if water temperature reached the maximum limit.
8. Temperature controls for the heating elements set too low (Page 9].
9. Possible burned out element(s).
B. WATER TOO HOT
1. Temperature controls for the heating elements set too high (Page 9).
2. Temperature control thermostat not working.
C. WATER LEAKS
NOTE: Always check for condensation first as the source of the “leak”. Wipe all wet surfaces dry and check again. Also, the
temperature and pressure relief valve may have opened to vent high pressure or temperature. Points to check on the water
heater for possible leaks are as follows.
CAUTION: TURN OFF ELECTRICAL POWER IF YOU WILL REMOVE THE ACCESS PANELS. Before repairing a leak, turn off
the water supply and drain the tank (see Page 10).
1. Inlet and outlet fittings.
2. Temperature and pressure relief valve connection, or the valve itself (see Pages 4 and 6).
3. Drain valve, or drain valve threads to tank.
4. Gaskets around heating element(s).
NOTE:
Improperly installed heat traps could cause reduced
or restricted water flow (see Pages 4 and 5).
