grams-
Thanks - hoping for the former but the area of the house it's in is a dodgy mould filled extension seemingly dug into the side of a hill so I won't rule out the latter. I guess I'll leave it switched off until I'm back later in the week and try a new RCD. It looks like this but reading there are type A, B and C:
If that doesn't work I'll call someone.
Perfect time (the night before traveling 7 hours to a job) to find out the washing machine never finished the cycle and has locked all my clothes for the week inside it... (have since stuck it temporarily on an extension to unlock it and hand washed but still..)
edit: hang about, is any paperwork needed for changing? I.E. is it a spark callout regardless?
CYOA
RCD has tripped for a circuit in the back of the house.
Fuse won't stay up. When I switched everything off / pulled plugs etc it remained up. As soon as I switched any of them on, it went straight back down (so it doesn't appear to be a specific switch/appliance).
New fuse for the consumer unit?
There's nothing in there we need (washing machine but can wait as am assuming it shouldn't run on a 10amp extension) but wondering if there is a checklist before calling electrician?
