How to Troubleshoot & Replace Whirlpool AP6008659 / WP35-6465 Washer Drain Pump Assembly

18 year old Maytag Atlantis top load washer had a load knocking and rattle sound with excessive vibration when the tub was spinning, but not when it was agitating. They was no water leaking. I took the front panel off and carefully listened while I ran a cycle and the loud sound sounded like it was coming from the drain pump. So I took off the drive belt and noticed that it was glazed and that there was belt material on the drain pump and tub transmission pulleys. I removed the drain pump and notice right away that I rock the pulley side to side and make the type of noise that I'd heard. The pump pulley did not turn quietly and I found a ball bearing under the washer. So it had to be a worn bearing in the drain pump. Also saw a fair amount of white shavings on the base of the washer, so I decided to replace the snubber ring and the suspension springs together since the cost was not excessive. So I ordered the drain pump, a new drive belt, in addition to the springs and snubber. I took the whole tub assembly out and left in upside down for a couple days in the kitchen as I waited for the new parts from Appliance Parts Pros. They got here within a couple days. Replaced all of the aforementioned parts after viewing a couple videos produced by Appliance Parts Pros (which I had watched very early in the process as part of the problem diagnosis). I had never repaired a washer before, but the videos made me confident that I could do it. That ended up being the case. It works like a charm now and my wife is happy it works again all within a few days. The most difficult part of the process was removing and re-installing the suspension springs. I used locking pliers to do it, but it still requires a lot of force to stretch those springs. I did it, but it took a lot of energy. 

Watched a few You Tube videos about the noise. Most came to the conclusion that the drain pump bearing was going out. Ordered the pump and watched Appliance Parts Pros video on changing out the pump. Easy as pie. 

Washer would not spin when loaded. Would go through all cycles unloaded and wet. Flipped it over and the pump pulley had aluminum shavings and belt dust. Replace belt and pump pulley assembly. Works fine. 

Acualy sounded and looked major but with a littel help with you tube the job only took 30 minutes. 3 bolts for the water pump pulley broken pulley poped off new one klick into place simple belt install good to go. Parts saved me $40 and where here in only 2 days. I couldnt be happyer. 

Washing machine is about twelve years old. I could not determine where the high pitched squealing noise was coming. I began by changing the belt but the noise continued. Changed the snubber ring and the noise continued. The water pump was the next suspect. There was a fine black powdery residue all around the pulley and bearing area of the pump. Changed the pump and the squealing has stopped. It appears that it was the bearing in the pump that was making the noise. 

After listening to a few videos, it sounded like the drain pump had gone bad. I watched a few youtube videos to figure out how to remove the front panel, since there was no access panel on my Maytag Atlantis MAV7200AWW. I removed the drain pump and spun it and heard a grinding noise so I figured that was the problem. The t/w a pro person at Appliance Parts ran down the correct part and I ordered it. When it arrived (next day) I installed it, replaced the clamps with radiator hose clamps, put front panel and belt back on and the machine ran like a charm. Only caveat was that I had a heck of time getting the belt back on the three drums. Best way was to put it on the smaller drums, then keep working it until you get it around the center drum... in other words, exactly the way you take it off. That and prayer, got the belt back on. 

The man with Appliance Parts Pros was very helpful with diagnosing the problem. We received the part promptly, and installed it without any problems. The washer is quiet, and peace has returned to our home. 

Replaced it with one ordered from this site. Hardest part was just getting the washer apart. 

Replace the water pump 

Ordered a new water pump and that fixed the problem. Now my wife still has a washer with a large(tall) agitator.
