Hello Bunny. You might just need to blow through the pressure hose and check it for cracks. Also, don't use to much soap. This can cause overfilling. Hope this helps.

Joel O. for Model Number cw20t5w

My washer wont retain the water that is pumping in it. Unless I hold the drain hose up in the air and let it drain untill it gurgles and then and only then will it hold water,and sometimes I have to do this process 4 to 5 times before it will work. Just to be clear it won't fill up with water at times it just runs straight through and drains out,hope you can help me. I've ordered a lot of parts from you guys and never have you been wrong so i'll put it in your hands now and wait for an answer. Thanks

Hi Joel. Your machine is siphoning back into the standpipe because of a couple of reasons. If the drain hose is more then 6-8" inset into the drain pipe it will create a air lock and allow the issue. Use the drain hose retainer part # WP22003814 to bend the hose accordingly to help. Make sure the standpipe is at least 2" circumference and is higher than the unit. Today's pumps (past 10 yrs) have high output capabilities so you do not spend as much time in the dryer (efficient).Make sure there is a air gap so the drain hose does not take the full inner circumference of the standpipe.Thank You.

Hello Eric. It sounds like the water valve 35-2374N WP21001932 is bad and will need to be replaced. We will need your serial number to determine which valve is the correct one for you on this washer. Hope this helps.

Hello Susi! Check the pressure hose switch to make sure it is clear and not kinked. If that is ok, check and replace the pressure switch. We will need your appliance serial number to verify the correct water level switch part number. Thanks!
