My machine has a strong odor of musty or mildew i run a load with bleach and this helps but it comes back the next day
For model number WM3431H
Hello Christine, thank you for your question. That smell usually comes from the front door gasket. If you remove it and clean it and reinstall that might help. The best option is to replace it. The part number is Part Number: PS3524984. I hope this helps.
Removed the top of the washer by removing the 4 back screws and 2 small brackets. Then I removed the front panel, this was actually the hardest part, 2 screws and 8 tabs that you pop out carefully from the top of the panel. I only disconnected the power button and was able to rest the panel on top of the washer. The rest of the washer came apart quickly just moving down the front of the washer and removing the door, latch, tub gasket, drain cover. Removing the pump was just a mater of disconnecting the drain hoses, and one clip under the drain assembly. 3 screws attach the drain to assembly to the pump and only 2 wires that are clearly marked. Reassembly is just going back through in reverse order of disassenbly. The best thing about this is that it all comes apart with a standard phillips screwdriver.
Thank you for the very helpful YouTube video. After watching the video, I was able to diagnose the problem, buy the part from your website, and complete the repair. This is my personal machine - I am not a professional repairman.
There are two pumps in this system. I turned the washer on its side and took off bottom plate. There are several screws holding this on. I then took the entire pump assembly off. There are 3 screws holding each pump on the brown plastic body. Each pump has a positive and negative lead. I switched out the pump and reassembled. The hardest part is getting the 3 "shock absorbers in place with the rubber sleeves. I think the book suggest getting to the pump from the front side but I went through the bottom. Worked good. I did wonder however if the other pump was working. Do you need two pump working to get flow? By replacing one pump I went from no flow to good flow. Cost me $75.00
