Removing rubber door ring from Zanussi Aquacycle 800

Unfortunately, once the door seal goes mouldy it is impossible to get clean. Only option is to replace seal. Once seal is replaced, you need to wipe it dry after each wash and leave door ajar to prevent reoccurence of mould.

YOU WILL NEED TO REMOVE DOOR SEALING RUBBER WHICH SEALS THE TWO HALFS OF THE DRUM THIS WILL ALOW YOU TO REMOVE SAID OBJECT

The problem is basically caused by doing too many low temp washes.

The scum you refer to is actually bacteria that is bulding up on the door seal.

To avoid this problem reoccuring, the best thing to do is to have the door seal replaced, and periodically do a high temp wash with powder in, but without clothes..
This is called a maintenance wash, and is recommended by most manufactures
Also, after each wash, clean and dry the door seal, this will help prolong it's life.
Hope this helps answer your question.

with both clips,< locking rings > removed seal it is removable by just working it off the drum slowly,< there is overflow tube in front bottom side to disconnect also>. It is very important when installing new one that you put it in the same positiont as old one and lock rings go on same as well.

Remove plastic clamp holding seal to cabinet and peel off the cabinet.push downwards on the seal close to the tub and the seal will come off - its just held by a spring round the periphery.

To fit new seal
Lubricate the slot which fits over the tub with washing-up fluid - essential
Starting at the top, press the seal so the flange of the tub enters the slot on the seal. Work your way round the using thumbs to force the slot on the tub flange.When slot is on the flange all way round, fit the spring which holds it on. The spring goes into a slot on the outside of the seal. this is quite difficult and you may need another pair of hands.
Fit the outside of the seal to the cabinet - this is easy and fit the plastic clamping ring.
Test for leaks before using in earnest. Use rinse to test as the water level is higher

Use tilex to remove the mold. Then see what happens. If the mold comes back right away it may be a problem with the rubber gasket not seating as it should. Let me know. And please rate my solution. thanks.

you have to check the electric door lock first open the door then take out the metal ring posted on the rubber seal then you have two scews on the font where the latch of the lock unscrew it and change the electric lock

Check your exit hose spigot, it may be clogged. This is if your filter is all clean. There should be air for passage in the standpipe behind. Your hose should not fit airtight into the standpipe and neither too deep into it. Snaking out your standpipe would be good too. Regarding the mould; keep your door open after yur washing is done, (means dont shut it tight) it will help to dry the insides & prevent moulding. Only see your cat is not inside before starting a new wash.
