MVWB450WQ1 Maytag Washer - Overview

Disconnect power, hot/cold supply and drain hose. Tip washer onto front side, expect some additional water to leak out. Remove the cracked drain pump, 3 screws, hose clamps, and electrical plug.

Tip washer back up, use the putty knife to pop the top cover up (clips are about 6.5in in from sides). Unclip the white plastic cover over the outer and inner tubs. Pop the center cap from inside the inner tub, exposing the bolt holding the inner tub down. Remove bolt, pull inner tub up and out.

At bottom of outer tub remove 2 screws from drain access cover, should find some change under there (or in the pump).

Re-assemble using new pump.

Note:
Before new pump arrived I was able to use some silicone sealant, epoxy, and black tape to temporarily fix the cracked pump housing after pulling it out.

You better be confident in your repair abilities before you try this. Get the washer to a large open area, like your garage, because there are a lot of parts. Take off the back, pop the top, unsnap and remove the top ring off outer tub, take out the agitator, take out the inner tub, disconnect the pumps and electrical wires, take screw out of rotor on bottom and remove rotor, take out 4 bolts to remove motor magnet ring, and now you may be ready to unhook the outer tub from the 4 supports (springs) and lift it out of the metal frame. Then unscrew the bottom nut on the shaft, use blocks to hold the tub in place, and carefully tap the old shaft and bearings out. The instructions that came with the kit helped. The shaft and top seal comes out the top first. Then you can tap out upper bearing and then the lower bearing and spacers.Instructions called for a special tool to install the bearings but you can carefully tap them in. You will need blocks to support the tub while you tap them. First block under the tub and install top bearing, then flip over and use several blocks to hold tub while you drop the shaft, spacers, and tap lower bearing in. I did not need to tap on the inner ring of the bearings, just the outer ring. Be very careful not to damage the seal in the bearings. That's why you must tap them in careful and slow. Them install the nut on the bottom. You need to hold the shaft with damaging it while you tighten the nut. I used the hard nylon gear from the inner tub which I was replacing with a new one. Then put it all back together.

The actual install of the pump was extremely easy. I removed the back cover, (After unhooking water, drain and electricity. I laid the machine on its front ( USE CAUTION WHEN DOING THIS, THERE ARE SHARP EDGES on the FRAME) After bandaging my cut fingers, I used a nut-driver/screwdriver to remove the screws, pliers to remove the Spring clamps, unhooked the wiring( its a single plug in) and reverse the procedure for installing.

I saw where a person had put the screws in the filter below the tub. I had to find the clips on the front of the machine, (about 7 in in from the sides) I removed the nut cover on the agitator, used a socket to remove the agitator, tub, and a nut driver to remove the filter. I found 3 areas where coins could get through the drain filter, and I used self tapping screws to make an obstruction that water could get through but not the coins. I reinstalled tub. Before re installing the agitator, I got some fiber glass window screening and cut a piece to go over the drain slots in the bottom of the tub but under the agitator, then reinstalled the agitator.

I noticed that the new pump had more re enforcing at the areas where the 1st pump broke. I doubt that it will break, but I am not taking any chances. I put the screen in to prevent the coins from getting to the drain filer 1st and the back up was the screws in the drain filter.
