Pen for Model Number Kudc25chwh1

Answer Hello Pen, The impeller should just pull up and off shaft. There is not a puller for it. 

Ricky for Model Number DU943WKBO

Answer Hello Ricky. The relay is made onto the board 8530929. Test for power on the grey and the red/black at the motor during drain. If none there, replace the control. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html

Richard G. for Model Number du943pwkbo

Answer Hello Richard. The motor changes directions to pump the water out of the unit. You will need to check the drain hose and make sure there are no clogs in the drain system. Also, make sure the sump assembly is not clogged. Hope this helps.

Answer Hello. Check the pump and the drain hose, and make sure they are clear of debris or cloggs. If so, see if there is power to the pump, and the pump is running. Hope this helps.
