The only way to eliminate a pump issue is to actually remove the pump and check it internally, it doesn't take much to block them and also the impellers can come loose, It sound like you are handy with tools so i suggest removing the drain pump and while it's off check the hoses that run to and from the pump for obstructions and make sure the impeller is not loose.
Ive had this happen on mine too. remove the filters in the bottom. squirt washing up liquid into the space-- liberally dont be shy! Boil pans of water, boil the kettle. pour water into the space where the filters normally are. Fill the base of the dishwasher completely. Next close the door and repeatedly use the Reset feature. Eventually the pump will clear and kick back into life. Its a build up of fats, and sludge that causes the pump to appear to seize--the washing up liquid and boiling water see to that.
If it IS the pump, it’s often because some relatively minor item (piece of cocktail stick/bit of nutshell/etc) has found its way past the filters and is blocking the blades of the pump. It is relatively simple to remove the inlet hose to the pump and clear the blockage (a pair of grips to pinch and remove the retaining clip, then the hose will slide off the fitting on the pump).I did this several times on my previous (Hotpoint) machine – and suspect it is no harder on the Bosch (which I now have).If that doesn’t work, you are half-way to replacing the pump, which is not a difficult DIY job and I’m surprised any competent professional repair man wanted to write off a machine where the pump had failed. A new pump should cost around £40-£50 – less than a quarter of the cost of a new machine.DIY fitting would maybe take a couple of hours; a pro ought to do it in less than an hour.
I have a Bosch Classixx with what sounds the same problem.It would not drain properly and hummed even when the front door was opened.After a couple of days it ponged a bit.This is what I did.Sypnoned off yukky water with a short length of hose (fill pipe with water from tap don't **** on it!!).Cleaned filter under cutlery tray at bottom.Then put a TEASPOON of bleach if on main drainage or dishwasher cleaner if septic tank.Ran on a hot wash and see if it sorted problem-it didn't but did clean system. Syphoned off again -take care.Isolated electric and water supply.-Should do that first perhaps Pulled out from under counter undid drain hose at sink end and water at machine end.I then put machine on side and undid bottom silver plate.Note position of polystyrene float switch cover.I then followed drain hose to drain pump and undid it by twisting it like a bayonet light bulb undoing clip levering with screwdriver (not for feint hearted as easy to break) -I then checked little impeller for foreign object-found none so pulled off pump housing by rubber hose to bigger pump thing next to it and found small bit of plastic put it back together and hey presto problem sorted-I was told it might take two hours for the expert to do it once on his workhop bench-it took me about 30 mins plus a bit of head scratching and a yank and push or two which could have been rather expensive -I was lucky!
without a brand or model number its hard to be sure, but some types have a float cut out switch inside the washer. Its on the bottom inside and kind of resembles a plastic mushroom. The top should lift up and down easily. detergent will clog it up and keep it from moving. Just clean all the soap caked on it and move it up and down to see it it pushes a little switch underneath.
fault is that there is a leak. the tray at base of dishwasher is full of water which operates a float and turns on drain pump. tilt over 45deg and water will run out and then it will work or remove bottom front panel and mop out (better). then find leak
