System Observation

For models with Direct Spark Ignition

Water Heater Fault: Water heater does not operate

Display Error Code: Water heater display does not operate - blank display

Check main power supply to water heater - fuse, circuit breaker, plug receptacle, line cord or wiring to water heater.

Check to make sure switch on front of

control panel is in the ON position

WARNING

120 volt potential exposure. Use caution

making voltage checks to avoid personal injury.

CAUTION

Use caution not to damage connectors when

making voltage measurements or jumping terminals

Verify Primary voltage at the

control board.

Verify Secondary voltage at the control

board.

Refer to Control Board illustration. Voltage at primary pins P2(1) & P2(3) will be 110-120. If not, check Line In pins P3(1) & P3(4). Check line cord with volt meter. Replace line cord if defective.

Refer to Control Board illustration. Voltage at secondary pins P4(1) & P4(2) will be 24VAC.

If not, check transformer. Replace

transformer or wire harness.
