Impeller on the dishwasher drain pump went bad. Ordered 5304463777 and replaced the unit. Dishwasher still not draining. Verified no obstructions on intake or drain lines. Verified power from timer. Getting 21.8 ohms across pump leads and open to chassis ground. Any suggestions?
Answer Hello Ogre,
You will want to check the filter to make sure that it is not clogged and also check down in the sump to make sure that there is no obstuction in the sump that is causing unit to not drain. Check to make sure that pump is getting power at the pump. You have already verified timer sending power. Check for broken or loose wires.
Just had an incident. Dishwasher is not draining. I have read the posts only question. What position of rotation should I have the switch while testing for power to the pump?
Answer Hi Mw. Just before OFF- the pump will go into a 2 minute drain. Open the door and advance the timer clockwise to one notch before off. Have you're meter lead prongs already set on the pump connector (with the pump disconnected). If you ohm out the drain pump to 28 ohms and each lead to pump chassis to see if the windings are shorted. If they are shorted then replace the pump part # [AP43618633]. If the impeller is spinning loose on the shaft - replace it also. Disconnect the drain hose under the sink and see if the restriction is there at the sink end. Thank You.
