Question about Whirlpool Duet GHW9150P Front Load Washer
At the end of the wash cycle and both rinse cycles, the washer pump extracts the water from the machine, but then continues to try and pump water for several minutes, even though it is empty. I believe the extractor pump is now pumping air and it makes a horrible thumping noise that continues for several minutes at the end of each cycle. The washer is located in our kitchen and I have to leave the room because of the noise. I had the unit replaced shortly after I purchased it, and the second one made the same noise. I had two repairmen come who both initially thought the unit had a problem, but after discussing it with the Whirlpool technical staff, they told me it was 'normal'. As an engineer, I can't believe the unit could have been designed this way! Can you help? Thanks.
Believe it or not, this is normal. The pump runs until the water is extracted and begins to cavitate as it pumps air. These pumps will make some noise. As long as it is draining properly, and your clothes are coming out pretty dry, I would not replace it. However, if you are experiencing louder than usual noises, you may have something caught in the pump reservoir. You do have to clean the pump occasionally. The following link explains how:
A new drain pump will run you in the neighborhood of about $70 to $80. You can order them online at searspartsdirect.com. If you've already had two repairmen look at it, replaced the unit once and it did the same thing, AND had the Whirlpool staff tell you this is normal, you may want to consider that there's nothing wrong with your unit. I know its hard to believe that someone would design something this way, but the manufacturers aren't perfect. I've worked on these units numerous times with similar problems and had to either tell the customer that there was nothing wrong with the unit and basically deal with the noise, or replaced the pump at their persistence. I just thought they were throwing their money away on something that probably will not change. I hope this gives you some answers, and hope it will help you in some way.
