Re: AEG OKO Lavamat 74630 update
Do you only use liquid detergents and low temperature washes. This would be the number one cause.
Try using powders and higher wash temperatures for your whites only washes, this will help. But once the door rubber has become discoulored due to mould it is almost impossible to get it looking clean again.
If it looks really bad then the only remedy is to change the door rubber I’m affraid.
Remember power off at all times and if your not too sure how to replace it, then it might be better to contact repairs@ for an expert engineer.
