Ive been to this m/c 4 times and customer is complaining of no heat ,
each time i call it works 100{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} ok, ive replaced front and rear stats cleaned condenser checked wiring, she also said that tank full light comes on when tank is empty, any ideas on this one cheers paul.
I agree with Bryan. Look for a blockage in the float chamber. If it’s ok when you are there and the customer has mentioned that the full tank light is comes on too early, then it’s much more likely to be float chamber problem than a timer fault
