Our washer dryer (Hoover WDM 120) stopped draining. Following previous
postings here, I checked the filter and pipes for blockages.
Eventually I removed the pump (well, I think it is the pump - a small
motor on the back of the filter chamber. The paddles seem very small
though).

There is nothing obviously wrong with the pump, but when I connected
it to the mains (I was very careful it didn't do anything, not so
much as a buzz or click. As there are only 2 connectors, I presume it
should start to work when power is applied?

So, do you think a new pump will fix it? There is nothing else
obviously wrong, the drum spins (after manually draining it) etc. I am
just worried that the pump might have burnt out part of the controller
when it failed.

The machine is a little over 2 years old, but it has been used pretty
heavily. It could last a good while longer or the bearings might go
next week. I am willing to take a gamble if it is just the pump, but
if it is likely to be anything more serious I will probably have to
cut my losses.

As you might have gathered, I am not too experienced at fixing these
things. I've owned a number over the years, but they always seem to
fail catastrophically so I've never attempted to fix one before.

Cheers
