I was going to treat my self to a matching washer dryer and dish washer when I moved last year. So in a dilema with mine as if something did get stuck and cause water ro stay in barrel them when problem is found maybe no repair needed. If it needs repair then I have 3 options rey fix it it me/mate. if not, then cost what a repair servive will charge.
Swap it for a washer dryer I have in the shed.
Sell both, buy new, but not needed the didh washer so far so not sure on that. :-/
Just as a bit of advice really..... a Washer/Dryer combined unit is probably the most unreliable bit of electrical kit in anyones home. Also, quite impractical. Say it has a 6kg load, you can wash upto 6kg of clothes.... but, the drying cycle will probably only be 3/3.5kg. Whats the point in that? You have to stop the machine, remove half the clothes and dry them in two stints.
They are also extremely inefficient (all dryers are, but Washer/Dryers are exceptional). The drum is foremost designed to wash clothes, with many holes in. A Dryer Drum will be pretty much solid, with very few holes.
Just generally a very bad idea. Even the extremely expensive, best brand Washer/Dryers (AEG, Bosch etc) are rubbish. 
If you need a new Washing Machine though, I cannot praise the later LG Direct Drive units enough. They are simply brilliant. Massive load figures, extremely quiet, quick and efficient.
A very fair point.
I hatewasher/dryers as suh, I bought this one 10 years ago as part a a set. Washer/dryer. seperate fridge and freezer frige since has packed up, a cannon gas cooker a sharp micro wave and electric kettle all for the bargain price of £220 Since sold the cooker, jettle and microwave still used daily as it the feeezer. Seller was changing it all to suit the colour of her kitchen, seems it is done evey 2 or 3 years.
In that 10 years I have used the dryer twice, I generally choose not to. The first time I was so glad it was there it saved me so much stress for a forgotton appoinment I had to attend.That was about 8 years ago. The last time was my cleaner takes the washing out and sorted it and tuned the dial to off. I hate anyony operating the washer and asked her not to do it agin, just take out or put laundry in, no proplem, when I went use the next time she had reset it and pressed the odd button, hene the dryer kicked in, was a surprise when I pulled out warm fluffy laundry rather than stuff slighty damp.
Still weighing idea's up, mine is a 1400 spin, so comparing 1600 washers and washer/dryers at the moment.
No major priory as I say regards as I very very very very rarely use a dryer, but still like it as an option, but 12/13 years with this hoover quattro has aprt from th squal been problem free till this door problem.
Single person, dont abuse technology and respect the overload/weight limits.
