Thermistors Troubleshooting Steps

Turn off breaker.
Unscrew cover.
Locate temperature sensors on inlet and outlet pipes. It is the nut with wires coming out of it.
Follow cable to electronic board.
Remove electronic board cover.
Disconnect from board.
Turn on breakers.
Turn on hot water tap.
Wait 3 to 5 minutes.

If water still does not heat up, further technical troubleshooting is needed. Volt meter is required.

If the water heats up, then the thermistors are bad. Just leave them disconnected (creating a bypass) until you can replace the thermistors.
