  If your dexPro Water Heater isn't heating and the indicator light is off, it could be due to a few reasons. First, ensure the main circuit breaker is turned on. Another potential cause is insufficient water flow; make sure the water pressure meets the minimum requirement of 0.05Mpa/0.5bar to activate the device. Finally, check that the water connections aren't reversed and that the inlet filter screen is free of any obstructions. Remember, the cold water inlet is blue, and the hot water outlet is red.

Why is my dexPro Water Heater giving no heat or little hot water, but the indicator light is on?

  If your dexPro Water Heater shows the indicator light is on but there is no heat or only a little hot water, consider these possibilities: The water flow might be too high; try reducing it. Also, verify that the device is connected to the correct voltage supply as specified on the rating label on the front cover. An 'E2' error indicates a faulty water temperature sensor, which requires replacement by contacting after-sales service.
