Had to change out my water pump as it would not turn on and the pump felt like it was getting warm, so I switched them out and found out from the mfg date that I had till end of this month May that it was still under the 3 year warranty so I sent it in and installed a new one.
But now back to my switch. I have noticed that since the old pump wouldn't turn on my pump switch the little red one next to the water heater switch just dims down when turned off. It comes on like always but when shut off it just glows dimmer and dimmer till it goes out usually 2 3 seconds, used to just shut off period. Anyone else notice this on their switch??
