MDB4650AWS Maytag Dishwasher - Instructions

I wanted to get the dishwasher cleaning better and thought that maybe the accumulator needed to be replaced. I figured that I'd swap out all the spray arms as well, just for good measure.

I needed Torx screwdrivers (T15 and T20, I think - not 100% sure on that) and patience because there's really quite a lot of screws to get the accumulator out. Finally got to it and it didn't look damaged, but replaced it anyway.

The spray arms are easy - they just snap in except for the lowest one, that had a plastic nut. I ordered a replacement nut just in case I broke this one (you know how that goes) taking it off. Well, it took pliers, but it came off ok.

In the end, my dishwasher is happy and cleans much better now.

The original brackets that hold the water distribution manifold to the back and top of the tub came off the "X-shaped" plastic posts on the tub walls. That caused the upper wash arm to sag down into the travel of the upper dish rack and was broken off when the rack was pushed in.
I bought 2 new brackets and a new wash arm. The new brackets had a smaller aperature than the originals and fit tightly onto the plastic posts, holding the manifold firmly in its proper location. Replacement of the brackets and the new wash arm took less than ten minutes and required no tools!

disconnected unit (electrical, water, and waste) un mounted from countertop, removed from under countertop, unscrewed hose clamb, cut off wire tie. Attached new hose and wire tie (not included) reversed above steps. Done in about 15 minutes

Not being very computer literate, the most difficult part of the entire venture was navigating your web site. But I finally found the part I needed. I paid on line with a credit card, and received the part within a few days. I popped it in the dishwasher, and it took three days before my son noticed it.
He was surprised and I was proud to say " I ordered it on line."
All's well that end's well.
I would difinately use your service again.

I unscrewed the door panel. removed the plastic cover protecting the dispenser. unscrewed the dispenser (6 screws). I removed the old dispenser and put the new one on and put it all back together. It was pretty easy.

First replaced rubber seal around door, which did not stop the leaking.
Then ordered insulation foam strip and replaced old one, which fixed problem. Put new strip over the old one because tub was slightly warped.
Very pleased with order speed and cost.

This isn't a how to fix it....it's what part was bad. I had originally contacted the local Maytag repair center and the owner swore up and down that our problem had to be the thermostat and not the heater. He said he had only replaced maybe 5 heaters in 15 years. But our heater looked like heck, with hard water deposits and all, and it wasn't that old, but we went ahead and ordered the thermostat from PartSelect, which came in a day. The problem wasn't the thermostat, so we ordered the heater from PartSelect (again, only one day delivery) and our dishwasher is working again. The heater coil actually had a hole in it from some sort of corrosion. My 18-year-old son did the repair job in a jiffy.

Unpluged the electric, Disconnected the water line and the drain line. Removed the dishwasher. Removed and installed the new water inlet valve and the float switch. This was a very simple repair. Reinstalled the dishwasher and connect
the water and drain line. Pluged in the power line. Turned the dishwasher on and it worked perfect. Thank you for the correct parts.

After replacing the door gasket and seeing that this wasn't the problem, using the schematics found at partselect.com I finally realized that it may be the insulation foam strip. I ordered the product and received it very quickly. Installation went fairly quickly. It was easy to remove the old foam strip and install the new one. The only problem was that the foam strip was about 1/4 " too short and it didn't cover the entire bottom. I improvised a little bit and cut off some of the old strip and covered the gap. So far the leak seems to have been fixed. In addition to the foam strip I had to buy a torx screwdriver for $11 at the local hardware store. The total spent was around $25.

All that was broken on the old detergent dispenser was the door but the door can not be ordered without buying the whole detergent/rinse aid assembly. When I got the new item I just removed the old door and replaced it with the new door that I had taken off the new one. I still have the new detergent/rinse aid assembly that I can keep if I need to change it in the future.

Used torx bit to remove screws on door and removed the back of door. Removed wiring from switches (2) on broken latch and removed latch. Plugged in switches on new latch and placed latch in position. Screwed back of door into place and that was it! Very simple task and new latch looks and feels much more sturdy than old one.

Turn-off the dishwasher power at the circuit breaker. Open the dishwasher door flat. Remove the 11 screws around the perimeter of the door using a t-20 torx bit (available at any hardware store). The latch assembly is held on by the top middle two door screws. Pull latch assembly out from top of door. Remove the black and white cable assembly connectors from the latch assembly making sure to note which side each color is on. If you have trouble sliding the connector off, use a flat screwdriver carefully to pry it, but do not pull on the wires. Install cable connectors onto new latch assembly making making sure the black and white cables are on the correct sides. Position the door at a 45 degree angle and place the latch assembly into position while putting the white inner door over it. Reinstall the 11 torx screws around the side of the door being sure the screws are snug, but not overtightened. Test the operation of your dishwasher. The new latch assembly seems to be built better than the factory original.

Removed the basketsThen removed the bottom spray arm with nut driver. Removed the cover and spray tower assembly. removed screw holding broken impeller. Replaced and reversed process. Really easy. As an aside. This dishwasher has been a major disappointment. lots of things not holding up. Didn't go cheap when buying it. Nice to find a site with good prices for parts

1. Fully opened door of dishwasher.
2. With star driver, removed 11 screws from the insde edge of door.
3. Outside front panel of door then is separated from inside panel slightly to again access to, latch assembly.
4. Verified that replacement part matched existing part.
5. Lifted out damaged latch assembly and disconnected the two electrical leads by gently pulling on the insulated connectors.
6. Connected the electrical leads to the coresponding connections on the new part and replaced in the reverse order of above.
7. Total time for repair was 15 minutes.

The repair is simple open the door and remove the perimeter screws and lift the door panel up. Be careful of attached wires. The handle only requires that you remove two electrical connectors and reconnect to the new latch handle and realign it with the screw holes in the door panel. The seals are not as easy to change they are attached with spring clips that I had to snipe through to get the old seals off. The new seals did not come with new spring clips, so I flattened the clips and reused them, they did not hold as tight, but seemed to work. Then just reinstall the panel.
