Are there any good dishwaher repair sites?
I've googled and googled but no joy!

Problem is Zanussi DW907 which is not doing as good a washing job as it
should.
Having listened to the cycle, it does not appear to be draining for as long
as it used to mid-program.
So far I have tried cleaning the filter out and, on the advice of a friend,
removing a small dome in the base of the unit and
removing/cleaning/replacing some U shape syhon pipes.
This friend suggested the trouble was likely a blockage effectively
preventing the full drain cycle and resulting in still-dirty-water being
used for the rinse cycle.

This does not appear to have solved the problem!

Can anyone advise on the following please:

Site for dismantle/repair instruction on dishwashers.
Likely cause(s) of the poor performance.
Other parts to be stripped and cleaned if my friend is correct in his
diagnosis.


Thanks in anticipation
