Washing Machine Drain Pump

Part #4681EA2001T
The drain pump and motor assembly may also be known as the washer drain pump and is a part for your washer. The drain pump helps expel water from the washing machine. The drain pump is activated after the spin cycle speed is maintained for a specific period of time. To make this installation you will need a Phillips screwdriver, a small flat-blade screwdriver, a pair of needle-nose pliers, and a pair of slip-joint pliers. Note that the pump casing is not included. This medium-difficulty repair may vary, but can generally be started by disconnecting power, then removing the top of the washer by taking out the four back screws and two small brackets. Then, remove the front panel by taking out the two screws and eight tabs that should be taken from the top. Moving down the front of the washer, remove the door, latch, tub gasket, and drain cover. Disconnect the drain hoses and clip from under the drain assembly, and install new assembly from there. Reassemble parts in direct reverse order -- taking photos during disassembly and keeping parts clearly organized can help here. Despite the number of steps, you will only need a standard Phillips screwdriver to complete this repair.

Water Inlet Valve - Hot
★★★★★

(18)
Part #5220FR2006H
This hot water inlet valve is designed to regulate water flow into the washing machine during operation. Featuring a standard hose fitting inlet and a single water outlet, it opens as needed to allow hot water into the appliance. If the valve is defective, you may notice slow filling, no filling at all, or water leaks. A simple way to test the valve is to unplug the washer when the issue occurs—if water continues to flow, the valve is likely faulty and should be replaced. The part measures approximately 3 inches in length by 3 inches in width and is sold individually.

Washing maching wouldn't drain

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 cam e 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 h ardest 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
