My tumble dryer is tripping my new fuse box off, when I press the start
button it throws the trip for the whole house. I have tried it on the
house circuit as opposed to the extension circuit and it does the same
thing. Nothing has happened to cause this that I can think of except
it was running as I turned the sockets off to do some work.
Yep, it has a fault. Current is leaking from the live bits to earth - so
not all the current that flows in the live wire is returning on the
neutral wire - so the trip, trips.
Which is the protection stuff doing its job - without it, the current
could have been leaking through you..
Basically, AFAIK, there still isn't a lot in a tumble drier other than a
heating element, a motor and capacitor and a timeswitch. So, it may
easily be fixable by a DIY person who knows how to use a multimeter. It
could cost as little as a tenner in spare parts - or could cost more
than the drier is worth..
Depending on what work you have been doing, you could have added
something which is also leaking a bit of current to earth. The drier was
maybe leaking a little, but not enough to operate the trip. However,
now, the drier + the extra leakage is enough to trip it.
