W225 - Overview

I found the water pump bearings were going bad from humidity. I replaced the pump with a new one and it runs quiet again.

I used a flat screw driver to push in on the releases so I could raise the top of the machine. I then used a torx tool to remove both parts of the hinge, and then used a #2 phillips screw driver, on the new screws I'd also ordered, to re-attach both of the hinge parts. Every thing went just as anticipated.

First unplug the washer for the electrical outlet. You will need to tip the washer back to get to the bottom of the machine. There you will see the belt that drives the transmission and the water pump from the motor. Remove the belt and set it to the side. Then you will need to gain access to the top side of the machine by gently using a screwdriver to pry the front of the top up off the front panel on both sides then hinge it back out of the way. Use a nut driver to remove the two screws on the inside edge of the front panel and remove the front panel. Once the front panel is off you will see the water pump on the right hand side as you face the front of the machine. Remove the hose clamp on the water pump with the flat head screw driver or nut driver and use a pair of pliers to remove the compression clip on the water pump. Remove the 4 bolts holding the water pump in place. Reverse the entire process to put it back together. This job was very easy and I was only without a washer for 2 days because of partselect.com.
