Bosch 500 series wfmc3301 bosch washer does not stop running the water during a cycle . even will do it with the spin and drain cycle. Even attempting to turn the washer off it will still run and then once the door shot open with water being forced out all over the laundry room . The entire bowl had filled with water until the force pushed the door open . ( in off position ) so the door happened to be unlocked.

are you sure it only happens in the spin cycle? and is the leak comming from the bottom front of the washer? most front laoders will leak due to a tear in the belows. that is the rubber boot that seals the washer tub to the front panel. if there was a hole or a tear in the bellows it should have a leak inthe wash cycle also. but there are also other possibilitys too.but its strange to only leak in a spin cycle due to the washer is extracting the water and not adding it. so check and see if it leaks in the wash cycle to and get back to me and we can go from there. looking through my training manual i dont see what could cause a leak in just the spin cycle

possibly the motor brushes.
take back panel off. disconnect motor. remove bolts holding motor in and take out motor. check condition of brushes

during transport there are fittings installed to prevent damage to the machine. The shaft may have got bent but before panic sets in try to check 1. that there is a gap between the mahine and units
2. that the unit is leveled.

Joe, Thanks for the prompt reply. OK, it sounds like one of two possible culprits, 1) the belt has broke or spun off. 2) the brushes in the motor are worn...although the initial symptom of this is typically manifest in "no spin" so I'd lean towards a broken or spun off belt. You'll need to remove the rear panel for a visual inspection to confirm or dismiss either possibilities. Let me know what you find out. If the belt is off check for possible reasons "why" ? It can be a loose drive pulley, ( the large one, not the motor pulley ) or simply an unbalanced load on the previous wash, just a heads up since you're looking around in there anyway. Of course the belt itself may be worn ( stretched ) or broke and thus at fault as well. Good luck, I'll watch your post. macmarkus :)
