Hi all

We have (had) a working Zanussi DW907 dishwasher.
My daughter, bless her heart, decided to put parts of a juicing machine in
it on Wednesday, without any initial degunging of fibrous fruit debris from
said parts.
I believe that the machine stopped at the beginning of the program cycle and
SWMBO removed the offending items.
Since then, the programmer will not progress through its cycle - advances a
bit then stops and waits for human intervention.
Also, the main CU RCD tripped out 3 times when my wife tried to use it
yesterday.

The question:

Could putting loads of fibrous materials into the machine cause this much
havoc? I am particularly concerned by the RCD behaviour!
Where do I start to try and rectify the damage?
It is likely that we will be re-furbing the kitchen later in the year, so I
don't want to buy another unit that is unlikely to fit in with the revised
design.
If we can extend the life of this machine for a few more months it would be
a god-send.

TIA

Phil
