Hot water and shore power

[corksailor]

The immersion was not working and borrowed the big spanner to remove it for replacement.We found 2 temperature probes the constant and the overheat.Using a small screwdriver we reset the little black pin on the overheat probe The immersion works again and no need for a replacement.The little black pin is hard to find and needs a small screwdriver to push in and reset,No need to remove or replace the unit Worth checking before replacing as a meter on the unit will show a non circuit.
