Same model as the one with the soap dispenser, as it happens...

Odd, this. SWMBO reported that the machine was making horrible grindy
noises while it was pumping out, but not while it was washing. But of
course, rather than switch off and wait for me to come home and take a
look, she lets it keep running until the end of the cycle and emanation
of what she described as an 'electrical' smell - I'm not entirely sure
which came first. Bless.

Anyway - sounded to me like a Foreign Body in the impeller, so I took
out the filters etc, unscrewed the cover in the sump, and sure enough,
found a hard lump of crud in the pump chamber where i'm sure it was
doing no good at all to the impeller.

Put it all back together, and the pump was clearly spinning fine now.
However, the machine now keeps running when you open the door; which you
have to do as all the controls are hidden on the top edge. I really
don't know what's going on - looks like a failure of some detector
switch or other, but what I really can't fathom is how this can be
related to the original problem of the part-jammed pump. Can't believe
it's coincidence??

Any thoughts
