Hi. Our Bosch dishwasher is 10 years old, and it does not heat the water, nor does it heat up during the drying phase. I think it will cost nearly 100 Pounds to get Bosch to send an engineer, and I don't want to do this if the likely response is 'beyond economic repair'.
What are the likely reasons for this particular problem, and are any of them fairly easily fixable?
Unless a wire has fallen off, it's probably a dead heating element. I think my Zanussi machine uses the same element for both functions - so yours probably does.
Is the £100 just a callout fee, or does it get you any labour? Either way, I doubt whether it gets you any parts. Looking on the web, an element for mine is 50-odd quid - so you're possibly looking at between 150 and 200 quid to get yours repaired. Bearing in mind that you can get a new Bosch dishwasher (don't know about model equivalence) for about £250, it may not be worth paying to have yours repaired. Fancy a bit of DIY? Or, have you looked in the Yellow Pages for independent repairers who may be cheaper - both for labour and parts - than the genuine Bosch variety?
Thanks for the advice. I would do some DIY, but there are no manuals available (that I can find), so it's going to be very hit and miss. I'll try a couple of independents. The nearest equivalent new one is nearly 400 Pounds, so it might be worth spending money on a repair (just).
GB coughed up some electrons that declared:
I found the Bosch dishwasher I have to be quite reasonable to work on.
One of the parts suppliers (this one IIRC:
has exploded diagrams of many models so you can locate the area you need to access and get the part number of the element.
It's a case of having a set of torx bits (Bosch like torx) plus your usual standard tools, a clear space to pull it out into and carefully taking bits off until you get there. Once you work out how to get the side panel off, or access underneath, they are not that complicated out of necessity, most things are laid out flat.
Then again, 10 years isn't bad...

When our office dishwasher broke last week, I went to the local Bennetts store and saw this:
Basic features but all you need for cleaning coffee cups.
Problem with the old dishwasher was knackered electromechanical programmer. Not worth repairing. Of course these days it's all solid state.
There's a generic Haynes manual. OK, it's a Haynes manual, but it is useful...
There is no heat provided during the drying process, it uses the residual heat from the wash cycle. It also fills up the matrix in the left hand wall with cold water to help the steam condense on the wall surface and drain away.
Does it have a hot and cold water supply, or is it cold-fill only ?
If there's residual heat from the wash cycle, the element would appear to be ok
That appears to leave only the program switch to blame, as any load switching apparatus sounds like it's working normally as it worked elsewhere in the cycle.
I've never taken a dishwasher apart though, so this might be complete b'locks.
One thing worth checking on a machine that old is that the wires to/from the Gubbins in the door have to run through the hinge at the bottom and get flexed every time the door is opened. After ten years or so the plastic insulation will have probably lost a lot of it's plasticiser and become hard and brittle, it can then crack and no longer support the conductors which work harden and break.
Worth checking.
