I've discovered when the pump motor runs for about a second, the RCD trips.... replaced the pump about a year ago.....
The unit uses a electronic push button system,... so could this be the water level probe? or perhaps a relay on the control PCB? or would it be a solnoid?
HELP!!! I've not had time to look at it..... and not had a coffee for 2 weeks... come on guys have you seen this before?
.... actually the if I put the power back on, the pump works.... it;s only when trying to fill the boiler...
would the fill sensor cause this???? or the fill solnoid ????
