Bh for Model Number samsung WA422prhdwr/aa My washing machine gave a ND code, no drain... I emptied the water, took apart the drain hoses, and drain pump. There was no debris. tested drain pump seems to work sometimes in test mode, I can hear it but water does not always drain. tried a load of wash 3 times, 1st load was fine. 2nd load had to empty water again manually, but his time the water level was incredibly high. to the point I thought its going to over flow, the weight was too much for the washer to move in wash cycle. Third time, washed normally, then went into spin cycle for a REALLY long time. In fact the timer went up in time after 20 min of spinning I turned it off restarted again and water went to high. Is this most likely a control board, drain pump, or water pressure level sensor, any thoughts?
Answer BH, you may want to test the resistance of the drain pump motor as it should read between 13.5 to 16.5 ohms. Another thing to check for would be making sure that the drain pump impeller is in good condition. If the drain pump has an improper resistance or an impeller that is slipping, this can cause partial drains which would result in high water volume inside of the tub. You may also want to check the pressure sensor hose for any clogs as this can cause high water volume as well. Read More... Answered by AppliancePartsPros.com | Friday, April 26, 2019
