Dishwasher Help Forum

It really is open it up time, however access to the internals on this Bosch produced machine is difficult, definately not a DIY job. Fault could be internal hoses gunged up or circulation pump impellor coming adrift. Plug out if you intend to proceed or try the link below to see if we have someone who can help.

I am suprised that the manual says that. The drain pump (which is most definately not the cause of your fault) can be accessed from the front, however that needs the door front panel and the large lower plinth and a few other bits removed to gain access. There is access to the flap valve of the drain pump from inside the dishwasher, under the filter but I say again, this is unlikely to be the cause of your problems. You cannot access the circulation pump without a major strip down involving removal of top, door, side panels and complete inner tub. There is a hose that often gets blocked that you can get at in the same way as the drain pump. it runs right across the left lower front of the machine but once again is really best left to someone with experience.
