Problem
Water does not get hot
1. Make sure the power supply is on and working.
2. If light does not come on, check that the reset button is pushed in; follow steps from previous
section.
3. 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. There should be no water flowing. Any continuous flow indicates a cross over which will
effect the temperature and will need to be corrected.
4. If there is no crossover, then replace the heating element (see previous sections).
