Bosch 00171598 Pump To Sump Gasket OEM Part

Hearing a metal on metal noise and not actually circulate water cancelling cycle worked fine After some web research, I concluded it was highly likely to be the circulation pump, so I watched the video on AppliancePartPros.com and realized it was a lengthy repair (a lot of steps) but not technically difficult. I simply played and paused the video at each step and duplicated the steps. The biggest things to take note of: 1) take good pictures of the wiring to use when you re-connect. 2) Wear gloves when reaching down between the housing and the base when disconnecting or reconnect components. The sheet metal edge where the sump mounts is VERY SHARP. I cut myself several times. 3) Pay special attention to the rubber mounts used to hang the circulator pump assembly. As the unit is laying on its side with the base partially separated they have a tendency to release for their hanging positions. Make sure they are in position during re-assembly.

Watched AppliancePartsPros video, disassembled the dishwasher and replace impeller and seals.

I replaced the gaskets with products from this site which I would not have been able to do without the video on this site. Hard job. The leak was still there though, so I have some hints with this kind of washer. 1) There is a float switch on the base that turns on the drain pump when there is a leak, that is why the drain pump runs constantly, it prevents catastrophic flooding in many cases. The float consists of a little styrofoam donut that lifts an arm, all white. The arm is connected to a red stick that, when lifted, starts the drain motor. About 1/2 inch of water activates the pump. 2) The fill system is weirdly complex and can get clogged which can cause a leak, look in the left wall panel if you dare. 3) The water inlet valve also adjusts water pressure, with standard water pressure there will be too much water sent into the fill system and it will overflow. 3) Be persistent, you can fix these.

The pump impeller came apart so it was not pumping the water and making noise. The dishwasher came apart easy but the gasket to the sump assembly stayed attached to the bottom of the tub and did not pull it off. I was running my thumb around the gasket to see if it was in good shape or if I needed to replace it and sliced my thumb open on the sharp edge of the tub opining. So a $150 later for Emergency Room visit and a sore thumb I re assembled the dishwasher. Be careful of sharp edges in this dishwasher. I turn the water and power on but the dishwasher and pressed the power button and the pump motor as just running with no water. I check all the connections, the float and everything else I could. the pump motor would just run with no water entering the dishwasher. I turned out since we stopped the dishwasher in mid cycle when we heard the strange noise I remembers this even through a power disconnect. The power to the dishwasher was disconnected for 3 day and I still new it was in mid wash cycle. Once I press cancel. And re started it, everything worked perfect.

Rebuilt circulation pump. New rear housing, bearing, seals and impeller.
