Zanussi ZSF6161 not cleaning correctly.
Had a phone call from a customer with a Zanussi ZSF 6161 that does not clean the dishes as well as it used to. She has used the cleaning tablets and checked the spray arms for blockages.
States that the tablets do not seem to dissolve completely as they used to in the drawer.
Dishes dry with lots of stains on them when the cycle finishes
Any quick checks before I set sail to have a look that are common with this model chaps. Partially blocked filter, sump/pump impeller etc.
