Solution
Make sure the power supply is on and working.
If light does not come on, check that the high limit reset button is pushed in;
follow steps in section 7.1.
If the indicator light works properly but 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 effect the temperature and will need to be corrected.
Call a qualified service technician to test the resistance of the heating element (8-10
ohms). Heating element should be replaced if readings are outside these values.
If the light does not come on, but water gets hot, check for faulty bulb.
Check high limit reset button;
follow steps in section 7.1.
Brown or rusty water indicates a "spent" anode rod and possible deterioration of
the tank body.
Inspect the tank for leaks.
Check anode rod (see section on changing the anode rod).
Check water fittings and T & P fitting on top of tank.
Remove front cover and inspect heating element gasket.
If tank is leaking call for warranty claim if still within warranty period.
Check anode rod (see section on changing the anode rod).
