Why is my Waiwela Water Heater not getting hot?

  If your Waiwela Water Heater isn't heating water, first ensure the power supply is on and working. If the indicator light isn't on, push in the reset button, following the steps from the relevant section. If the light is on but the water isn't hot at the sink, check for a plumbing crossover by shutting off the cold water supply to the heater and opening the hot water tap. Continuous flow indicates a crossover. If there's no crossover, replace the heating element.
