I know what's wrong with the washing machine, it gets a bit damp because it
lives in an outhouse since its home in the kitchen got taken by a
dishwasher, and the damp causes a short occasionally. I learned that last
time I called out the repairman.
It's on a timeswitch to use cheap rate electricity, it clicks on at 2am and
trips the fuse.
Before calling said £85 repairman out again to remove a drip of water, any
thoughts on how I might do it myself? I can get the top off. Waggle a
hairdryer round for a while? Splash WD40 everywhere?
Any sensible suggestions appreciated. It's a Candy btw
Is it blowing a fuse or tripping an RCD? There is a lot of difference
between the two.
You could consider putting a very small heater under/in/behind the
machine. Just a few watts may make all the difference. I am thinking of
the sort used for keeping the damp out of pianos. A blanket over the top
would keep things cosy. Actually, almost anything that gives out a few
watts of heat will do, lol, even an old defunct Sky box..
If it is blowing fuses, it won't be long before it will need more
drastic repairs. If it is just tripping an mcb, you could possibly put
it on a fused supply or replacing the mcb with a wired fuse. I wouldn't
recommend it but it may work.
I had a washing machine that would trip an MCB on startup but not blow
an "equally rated" fuse. Hence the suggestion to try a fuse.
IIRC, MCBs use a magnetic "instantaneous" fault current trip and a
thermal "time-delay" trip. They are far more precise than an odd bit of
fuse wire so may trip, quite correctly, whilst fusewire may take an
overcurrent for longer than it "should" - if it is, say, in a very cold
and draughty fuse holder...
Long time ago, but i2t graphs spring to mind.
Never did work out whether my machine was tripping on thermal or
magnetic - I got a replacement instead. It was *very* elderly..
The discrimination rule
Which will react first? A 20 amp MCB or a 13 amp BS1363 fuse (the one in
the washing wachine plug)?
They are still there.
The reason I suggested that a MCB/fuse swap is irrelevant in this case is
that water and or damp will not pass enought current to trip either of them
instantly. It had to be an RCD trip or a short circuit in the machine.
