Our washing machine I hope.  Woke up this morning to find it hadn't drained.  Did a manual drain and cleared a load of crud from the pump but it still wouldn't drain even though the impeller was working fine.
I'd already cleared the inlet so reckoned that a blockage in the pump outlet/hose might be to blame.  I put the machine on its back and found the pump is readily accessible from underneath and without taking the top, control fascia and entire front panel off - what joy!!!.  It's actually a two part pump and the main electrical gubbins part can be twisted off leaving the drain housing and pipework intact.  I couldn't see/feel any more crud in the housing so figured the flexible drain hose might be blocked.  After disconnecting it from the drain housing I was able to pass it out of the back of the machine into a large bucket.  It was then just a matter of connecting my garden hose to the other end and turning on the water.  I was amazed at how much smelly grey compacted slime came out - it was like a corrugated 8" turd 
 
 
Anyway rather than put everything back first,  I reassembled everything, filled her up and the machined drained beautifully with no leaks apparent.  The washing's on now as a test run to make sure everything works properly but the signs are good so far, touching wood...
 
The good news is that I now know how to replace the pump if that ever packs up.  It ought to be a very simple job.
