BASIC TROUBLESHOOTING
SYMPTOM: NO HEAT AND THE POWER INDICATOR LIGHT ON THE CIRCUITBOARD IS “OFF”.
1)
Verify the heater is mounted to the wall correctly. “Single Point” has the brass fittings pointed
“UP”. “Flow Controlled” and “Thermostatic” have the fittings pointed “DOWN”.
2)
Verify it is plumbed correctly. The cold water INLET is on the “RIGHT” and the hot water OUTLET
is on the “LEFT”.
3)
No electrical power to the heater. Switch the breaker “ON”.
4)
Incorrect power supply. Make sure the heater is connected to the voltage specified on the rating
label on the front cover.
5)
Not enough water flow through the heater to turn the heating element “ON”. Check the inlet and
outlet ball valves to make sure they are open. Also check the inlet filter screen inside the inlet
fitting to make sure it is not plugged (see page 4). Clean or replace the aerator at the faucet.
6)
Still NO HEAT? Contact Eemax. Call
203-267-7890
or
800-543-6163.
SYMPTOM: NO HEAT, LOW OR INCONSISTENT TEMPERATURE WITH INDICATOR LIGHT “ON”.
1)
Water flow is too high. Reduce the water flow by slowly closing the OUTLET ball valve.
2)
Incorrect power supply. Make sure the heater is connected to the voltage supply specified on the
rating label on the front cover.
3)
Electrical heating element is burned out. Turn off electrical power by switching the breaker “OFF”.
Use an ohmmeter to test the resistance across the two threaded terminals at the end of the
element. The resistance varies, depending on the model of the heater, but should be less than
30 ohms. If it is much greater or fluctuating, contact Eemax for a replacement element cartridge.
If you need any assistance from our Technical Service Department, make sure you can identify this water
heater by having the model no:____________________ and serial number:_____________________.
