The drain motor on my Bosch dishwasher will not turn off. I put several gallons of water in the machine, and it pumped out fine - but the motor will not turn off when finished draining. The unit is about 5 years old. I cleaned the filters and tune off/turned on to try to reset. Nothing helped.
Answer Floyd, A model number for the dishwasher would have been more helpful. But the basic version is, the power to the drain pump motor is supplied directly from the timer or control board. So, you're going to need to check the wires to the drain pump motor and make sure theres no shorted wiring, check the timer or control board circuits for a "stuck" or shorted contact/relay.
Suds, many many suds at the end cycle and after many cycles without soap. It started about 5 days ago . Have historically used 1/2 the recommended additives. When the problem started reduced additives to 1/4. Detergent - 'Finish', Rinse Aide - 'Jet Dry liquid', Water Conditioner - 'Lemi-Shine'. Water level fills to bottom of door. Drains are clear. Water circulates very well in washer. At end of cycle there is approx 1" of water in the bottom (sump). I'm tempted to replace the drain pump. I've looked at it and the impellers look to be in good shape unless there is supposed to be soft rubber at the end of the blades. The blades of the impeller are hard plastic. I wanted to check the float and float switch but did not know where it was located. Any idea on the suds? Replace the drain pump? Thanks, Peter
Answer Hello Peter,
At some point, someone has put dish washing detergent for the sink in the unit. There is no way regular dish washing detergent can act this way unless WAY too much was added. Here's what to do to get rid of the issue. Put in one tablespoon of a vegetable based oil, (vegetable oil, corn oil, peanut oil, etc.), and let the machine fill and run for at least 5 minutes. This will kill the suds and allow you to drain it all out of the unit. Now you have to get rid of the oil. This is done by making sure the water filling the unit is hot and start the machine on a normal cycle. The first thing you will hear is the unit pumping out. Then you will hear a hissing noise which is the unit filling with water. Open the machine as soon as you hear the hissing noise and pour in 1 quart of white vinegar. Close the door, turn off the heated dry, and let the unit run through the complete cycle. This should get you back to where the manufacturers' recommendations will produce a satisfactory wash result without replacing the pump and motor assembly.
