My son and his wife moved into a house about 7 months ago, they have had a new consumer unit and a new combi boiler fitted about 5 months ago and everything has been fine up until now. My daughter in-law phoned the other morning to say that the electric had gone off in the house and everytime she attempted to reset the rcd it would just trip straight off again…I told her to switch off all the mcb’s and then reset the rcd from there she turned every mcb back on one by one until the rcd tripped again and it was on the ring main that it tripped so I told her that there was something usually kettle or washing machine that is causing the rcd to trip…the last thing she unplugged was the combi boiler and then the tripping stopped and also the electric stopped on once the combi boiler was plugged back in. Later that morning I went round to pick our grand daughter up whilst I was there I just tried a few things but as soon as I turned the kettle on the rcd tripped…I said I’m pretty sure it’sthe kettle. Later that day she bought a new kettle, when I spoke with my son the next day he said it tripped again when she was hoovering and also when they used the new kettle one time???
The combi boiler sits in a utility room with the washing machine which are both plugged into a double socket. The following day I went round with my insulation resistance tester to check earth leakage on the boiler and kettle even though the kettle is brand new, but all was ok apart from the washing machine which was just over3MΩ. What I did next was to plug a rcd adapter into the plug socket then plug the boiler into the rcd adapter turned the power on and everything was ok then I turned on the kettle and then the hoover after about 30 seconds the rcd tripped on the mainboard as well as the rcd adaptor that the boiler was plugged through???It looks like a fault on the boiler…but I don’t understand… if there is a fault on the boiler why it isn’t tripping constantly and only tripping the rcd when other appliances are being used? I would be so grateful if anyone could help meunderstand what might be happening here, but be gentle it is my first post!!!
Also are thereany regs that state whether the boiler should go through a switched fused spur instead of being plugged directly into a double socket?
Thanks in advance for any help and advice given.
