Thread: SHE4AP doesn't drain

Hi. The usual dishwasher won't drain topic, but for a newer model. Installed less thn 6 months ago. Won't drain water out. Have used the SHU service manual to do diagnotic tests on it. The drain pump spins at the beginning of the diagnostic test, the washer fills with water, but then, drain pump won't spin to remove the water and fails. Could it have something to do with the dirty water sensor thing in the drain? The pump seems to not spin when there is a lot of water in the washer, like above the filter screen. I removed the drain hose from the pump itself, and when it drains at the beginning of the test, the water doesn't fly out real fast. Sort of dribbles out the pump. I tired blowing out the drain hose from the drain pump end and I even blew air into drain pump from inside of washer and couldfel air coming out the drain pump. Could there be a clog between the impellar itself and the drain hose? The impellar spins freely. Does the pump remove by just turning it clockwise to remove it?
Thanks,
