I first removed then catch on the pump housing and found it was full of a collection of 13 year old solidified detergent and other junk (including 5 coins incrusted in the junk). I then cleaned the trap and replaced it back in the pump housing. I ran the washer several times and still got the error 2 out of 3 times. I then ordered the replacement pump from Appliance Parts Pros. The pump arrived in 2 days. Yeah!
I had previously watched the video on how to replace the washer pump. Unplug the washer and shut off the water. Remove the bottom cover by unscrewing the 3- T-20 screws. Flip up the power connector cover and remove the power connector. At this point, get a towel and place it close to the hoses connection before you remove the first hose. Use channel lock pliers to remove the hose clamps on the pump. Expect a rush of water out of the first hose you remove from the pump. I found a shorter handle channel lock pliers worked better to get in position to remove the hose clamps.
My pump had a #2 philips head screw in the front of the base holding it in the washer. Removing it I was able to remove the old pump. I had to use the smaller rubber bushings on the back of the pump to fit my washer. On the front of the pump, I had to remove the bushing an use the grommet and brass bushing. I was then able to install the new pump. Make sure the bushings on the back of the pump are correctly inserted in the holes in the washer. Reinstall the hoses, the power connector and then the bottom cover and you are done. Congratulations.
I did a tear down of the old pump. The impeller was partially worn away and would wobble and jam on the pump housing. Definitely a bad pump.
