Bosch Exxcel WFO2465

You are not alone with the grunge issue as most machines seem to suffer from this affliction.Trouble ,writing in a general sense,that in order to get the AAA energy grade the h2o level is too low which causes encrustation of sludge just above and including the door seal level;this combined with ,and i think your model is soley cold fill from memory only, rather than a mixed or hot fill ,depending on the programme setting, does not help the machine at all.Have been and still am a washing machine engineer for 30 years (grey hair proves it!) it seems the crux of the whole problem really lies in in the detergent and liquid detergent we all class,in the repair trade, as a killer,ie the machine slayer-no bleach in the product=smelly machine from bacteria that builds up after year 3 of ownership and everyone using bio detergent at 30 or 40 degrees.In very servere cases the fungal growth(yep,that`s what it is) attacks the aluminium spider assembly-the part you can`t see that bolts behind the drum that carries the bearing shaft-this part rots and then fractures and to all in tense and purposes writes the whole poxy machine off.I`ll agree with you that at the stage your machine has got to no amount of descaler is going to work now as it is too late;if your machine had had regular treatments or better still was run on softened h2o you would not have had the problem.You cannot wash modern fabrics without ruining them like you could wash and get away with with most stuff you wore back in the pre 70`s, sadly (in away!)times have changed; put it another way,if there was a G rated machine (the equivalent to a 1970`s built machine) that had high level water useage and was really bad on energy,though was hot fill from your water tank- just time things to coinside with bath night to kill two birds with one stone as it were!Then noone would buy the machine even though it would last alot longer(given also that 1000 spin speed is really the max and no faster for health of the bearings on a front loader)because of such a lousey rating grade.The whole thing is a total farce and a charade part manufacturer part detergent products part green agenda,but noone lisens,even the newspapers don`t understand the concept-or maybe they do ,but are not too happy being seen to attack the green agenda(which i support,but intelligently support that is!-i`m against wind farms for example as a complete waste of time and money in their present design form).So their you have it.It is somewhat more complex than this i have to say-molecular structure of the water tank material/ionic structure of h2o for instance and how ionic attraction between these two fundamentals and the detergent inter relationship,but i hope everyone who reads this gets an insight into the wacky wonderful world of the washing machine problem of ponging and their generally short life span.

I have the same problem and have had the tray out and given a thorough clean still not solve the problem, would never buy another bosch.
