Our 3 year old Bosch dishwasher has developed the following fault:
At the end of the cycle, the pump will run continually, even with the
door open. Tried a reset, by holding down two of the programme buttons,
and this has no effect, other than the "end" LED lighting up. Pulled
the unit out to have a look at the pipes etc, and this cured the pump
problem, until the end of the next wash cycle, where the problem showed
up again. Is the pump on a "timed" cycle at the end of a wash, or is
there some sort of sensor that tells the controller when the machine is
empty of water?

Cheers

Can't be of much help but we had exactly the same problem with our Bosch
dishwasher (only a few months old). Lifting the front of the machine cured
the problem until the next time. Called for help under the warrantee - the
engineer was *very* helpful. Took a few panels off and found water where it
shouldn't have been - that was why the pump kept going - he thought it was
a leak but couldn't find one. He then siphoned out the water and that cured
the problem. He admitted he hadn't found the cause of the problem and said
if it happened again to call again - it hasn't :-)

 I'm usually full of moans about customer service but can't fault Bosch
after sales service - or Comet where we bought it.

Its the anti flood system it will have water in the plastic base, remove it
find the leak and the problem will be cured

Thanks for the replies, pulled the machine out, drained the water, and
bingo! Does anyone know how the anti-flood system works? i.e. how does
the control system detect that there may be a flood problem?

there is a float that rises and operates a microswitch, have you found the
cause of the leak ?
