i have a bosh nexis 500 washing machine as soon as i turn it on in any setting it imediately pumps the water out as fast as it comes in anything i can do to fix it.
Dale look down several threads, Bosch Nextt 500 Washer Problems, Might be of some help.
Most new front loaders do this at start up, to flush out the sump water that could be sitting there for a while.
I will assume that eventually the pump turns off and your Bosch fills, if not call for service.
Does it have an AquaStop feature? Continuous draining usually means a leak was detected - dishwasher do the same. Or the software (board) might be faulty.
