Water does not heat up
1. Make sure the power supply is on and there is power available.
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 works properly but the temperature does not get hot at the tap,
test for a plumbing crossover. Shut off cold supply to heater and open hot water tap.
There should be no water flowing. Any continued flow indicates a crossover which
will affect the temperature and will need to be corrected.
4. Replace heating element (see previous section on changing the heating element).
