Hi, I have a problem with no hot water from the 105HE boiler. The pin that activates the microswitch on the front of the pressure differential valve isn't moving. The diaphragm was replaced only a month ago.
Is this the sole cause of the pin not moving or could it be another diaphragm within the diverter assembly?
Thanks for your help.
