Uneven grinding whirl sound during certain parts of the cycle
The first thing I did was to pull the clothes washer away from the wall far enough that I could access the back side. My model has a small 15 inch square access panel towards the bottom that allows one to access the interior where the wash basin, drive train, motor and pump are located. After watching a few of the very helpful fix it videos online, I also noted that the pulley and drive belt were located on the under side of the washer. So I oriented the washer away from the wall so I could lean it back and also take a look at the underside to inspect the belt. The sound that I was hearing was something between the noise you might hear from a car whose belt has gone bad, or the sound that a large rolling commercial cabinet with big caster wheels would make when its wheel bearings are shot. The later being more of a grinding noise where the former is more of a whirl or squeal type of noise. Based on what the sound reminded me of, I naturally was interested in any parts of the washer where there might be a belt and things that turn with bearing like parts. Upon inspection of the belt under the washer I noticed that the belt was delaminating in a small 1/2 inch section, which suggested that this was an easy diagnosis and fix - it needed to be replaced. However, the sound the clothes washer was making also had a hint of grinding that was uneven in nature, suggesting the real problem was more metal/mechanical in nature. I returned the washer to its upright position and ran a small load with the cover to the access panel off, so I could see the wash basin, drive train, motor and pump in action. I was particularly interested in seeing if I could more clearly identify where the grinding whirl sound was coming from and what part of the cycle it was being caused by. The sound happened at certain times which also provided some clues as to what might be causing it. After listening and watching a cycle through the access panel, I determined that the sound was not the motor and didn't seem to be associated with the drive train or the basin. All that was left was the drain pump. At this point, I returned the washer to its normal location and ordered both a drive belt and a new drain pump from this site. A few days later the parts showed up on my doorstep earlier than promised. I then returned to my washer and pulled it away from the wall again so I could easily access the back and the panel. I also positioned it so I could lean the washer far enough to access the under side where the belt is. The belt drive is made up of the motor, the basin drive train and the drain pump. That is to say that the motor spins a pulley to which the belt is attached, which in turn spins the basin pulley or the drain pump pulley depending on the direction the motor spins. The first thing you must do before you start poking around and removing anything is to unplug the unit from the wall. Don't be stupid and choose to die on a laundry room floor. Once unplugged, leaned the washer so I could remove the old belt. I recommend watching the belt video as it shows the technique for removing and installing the belt - it is super easy. Takes less than 20 seconds. Before installing my new belt, I leaned the washer back to the floor. The belt creates some tension on the drain pump since they are connected by way of the pulley under the washer. It is necessary to remove the belt before attempting to remove the drain pump. Removing the drain pump is slightly more difficult than the belt, but completely doable for most anybody. Again, I recommend watching the very helpful drain pump video offered online with this site. The hardest part is dealing with the hose clamps. Using an adjustable pliers you have to simultaneously pinch the clamp while sliding it up and off or over the hose. Once you do that you are half way there. You can then slide the hoses off the plastic pump inlet and outlet. I recommend making sure you have run a full cycle so that your basin is as drained as it possibly can be. My pump was working well enough to do this before I started the repair job. Even then, when you pull the hose off the inlet or outlet of the pump, you will have approximately 3-5 cups of water drain out of the hose. Not a big deal if you preposition a few towels around the base of the inlet and outlet of the pump. The second source of water is the water in the pump itself, which will spill a little as you start to remove the pump. To remove the pump you simply need to loosen three screws with a socket and driver. It can be a little awkward to get your tools in a position to loosen the screws, but there is enough room to do it. Once the screws are loose, you simply lift the pump off the floor and with it comes the drain pump pulley that the belt underneath is connected to. The next step is to install the new pump doing everything in reverse. Place the pump in the floor hole (new pump comes with new pulley), attac
