If the indicator light is illuminated, but water temperature does not get hot at the sink, test for a plumbing crossover as follows; shut off cold water supply to water heater and open hot water tap.

Unplug the water heater.

Open a hot water faucet to let hot water run out. Allow water to flow until water is no longer hot.

Turn off the cold water supply to the water heater.

Close the hot water faucet.

Disconnect the water heater from both the hot and cold water connections.

If possible siphon out remaining water.

Carefully detach the water heater from the wall.

Tilt the water heater to drain remaining water out of the heater.
