got a job to go to tomorrow

lady has had someone come to service her boiler,
after he left boiler was making what she described as a horrible rattling sound, then it tripped the rcd on the fuse board. She went on to say now every time she turns up the thermostat the rcd on the consumer unit goes plunging her flat into darkness.

i know she has a conventional heating system with a f & e tank in thre loft, from her discription the boiler is fine when it fires for hot water, but as soon as it fires for heating rcd goes

i'm wondering what on earth this bloke could have done,
the only thing i think of which would cause this is he's re wired the room stat, but why you would do that on an annual boiler service

any other ideas of what could cause fore mentioned symptoms so i'm not lost and stuck for ideas tomorrow
 
Maybe an issue with a zone valve. Could have bled something and got water in there. Maybe a gravity hot water and pumped heating setup an he has played with the pump and knackered it.
 
an rcd will trip on an earth fault, so live or neutral going to earth. if this is happening only when you switch a certain item its going to be that item or something it puts power to at a guess.
 
sounds like water in either the pump or the motorised vale to me or even valve
 
turned up at pre arranged appointed time, but nobody was home :asshole:

looks like its will remain a mystery, i'll give people a second chance in the summer months, but when its winter and busy she can freeze to death
