ideal response 120 keeps tripping electrics ?
if it has the old style water pressure switch its more likely to be that.

simply put - it's Fkd
most likely cause is a failed heat exchanger leaking into the burner and shorting the electrodes.
Ghastly boilers is the only description.

Be careful or you will get Nickso asking Kevin how on earth the leaking CC can trip the house RCDs.

It was Kevin who did not explain how a leaking diaphragm could cause the system pressure to increase.
