have looked at
Zanussi ZDT6053 prod No: 91139202/02
it appears as if the rinse aid dispenser is leaking when closed
it is difficult to see exactly where it is leaking from
the rubber gasket seems very soft and will not fit or hold in its recess on the dispenser lid
when dispenser lid is in the closed position, if you put door to nearly closed,re open there is a slight trickle of liquiud visible.
I suspect its the gasket but thought I would check it out as I have never come across a similar proplem in the past.
thanks for any help
Graham
