Hi, I'd be grateful for some wisdom on the following so I can be an educated consumer when the pro comes calling (or maybe it's even something I can fix myself ).
Set up: Potterton boiler downstairs, hot water tank and Potterton EP 2002 upstairs, separate fused switch upstairs.
Display to EP went blank. Can't remember if main RCD was tripped, but fused switch would spark when switched on. Tried a couple of times to switch on, but could get no display to EP.
Called out plumber. He charged for an hour to change the fuse in the fused switch to 3 amp and 'diagnose' faulty EP. Said the fuse amperage was too low (but we didn't see what it was).
System worked for less than a day, then the EP went blank again. RCD definitely not tripped this time.
We decided to change the EP ourselves (to a Potterton 2). (Didn't call out same plumber as he said it would be £100 for the EP plus a further hour to fit!) Fitted it today in 10 mins. No display until we also replaced the 3 amp fuse. Display was on for a few minutes and then blank again. Main RCD not tripped. (Also a little confused as to why there's no display at all given there's a new back up battery in the new EP, but perhaps that's my ignorance?).
We're planning on calling out an electrician, but would appreciate some educated thoughts on the likely fault and fix. Thanks in advance!
