MDB4000AWB Maytag Dishwasher - Instructions

Removed the 6 screws holding the pump and motor assy. Disconnected the two hoses and wiring connector. Removed the motor and pump, removed the pump parts to get down to the impeller. Removed the old impeller (one screw) and installed the new impeller. Put every thing back together and it worked fine. Every one is happy!

I first removed both lower front shields,(4 screws)
I then shut off water supply to inlet valve from hot water supply. I removed the water hose from inlet valve,two electrical terminals,( I put tape on right side terminal and lettered with an R as not to mix up the two terminals)removed the hose clamp,removed valve from frame.I reins ...

My handy husband was able to take it apart easy, and then your online site was great at showing us exactly which parts were needed to replace. Then a few mintues to put the 4 pieces together and now I've got all the room I need for the extra dishes!!The whole experience was so easy and very helpful!! thank-you very much!!

I first removed the bottom access panel and 2 upper screws holding the dishwasher to the counter. Be sure to remove the standing water in the bottom tray. I pulled the chassis far enough forward to reach where the top shower hose attaches ( the supply line and wire had enough slack to move the chassis ). Not knowing how the rotating sh ... Read more ower arm attached, I unscrewed the ribbed retaining ring above it, and found the whole assembly came loose - freeing the upper end of the shower hose. Put a shallow tray under the lower end of the shower hose to catch the remaining water and loosen the hose clamp to free the remaining end of the hose. Transfer the rubber washer at the top end and the hose clamp at the bottom, to the new hose and install. A quick repair, but one that shouldn't be needed on a 4 year old dishwasher.

I removed the old door gasket and thoroughly cleaned the track. I placed the new door gasket in place- no problems.
I had to remove the 7 screws from around the door to access the old, crumbled gasket. This was accessed by removing 2 screws with a socket wrench. The old gasket pulled out and the new one slipped right in.

Just snap the new spray arm into place. One minute or less.

Although the (top) dishrack assembly included the nylon wheeles, it was easier to replace the old one by disengaging it from its wheels and installing the new rack on the old wheels kept in the slider track. The snap hook that held each wheel to the old rack was popped loose (finger pressure) and the old rack removed. The new rack was he ...

The most difficult part of the 'repair' was removal of the handle from the old silver ware basket. I used screwdrivers to simultaneously pry the four tabs of the halde out of the slots on the basket and pulled (hard!) the handle off. It snapped easily into place on the new basket.

Turned off water at valve, removed float switch, removed water inlet vlv. Replaced and reassembled. Still not water going into the machine. I have no voltage to the valve or float switch. I then took the door apart to find there were burnt wires as well as a burn mark on the control panel. Upon closer inspection, it looks like the do ...

I simply connected the two hoses to the valve plugged in the two wires and it was working!

Unscrewed the inside door panel. Removed the reservoir assembly. Disconnected the wax motor. Replaced it with the new motor. Replaced the new o-ring. Done. The hardest part was finding out why it was not working and how to fix it. Google for a long time in order to find some idea what to do. Then took the door apart to see the reservoir a ...

The problem was the rubber end on the upper shower head pipe at the pump. Not to hard . Slide dishwaser half way ouy the ptpe is on the right side.The bottom end is is just a clamp the top drops in from the top, inside there is a nut above the upper shower head. You can unsrew the nut with your fingers, it is right above the upper shower ... Read more head.There it a washer at the top of the pipe that should be replaced that doesnot come with the pipe

The top and bottem spray arms plus the secondary filter located on the bottom of the dishwasher were 80% blocked with dishwasher soap which would not allow water to rinse the dishes completely.
The upper spray arm had fallen off, so I was able to quickely replace it with the new arm and clip by simply inserting the clip into the sp ... Read more ray arm and pushing it into place.
The lower arm came off easily by turning the large knob on top off it and pulling it off. After removing the arm I was able to access the three screws that release the secondary filter cover. The screws required a set of star sockets to turn them.
I then put the filter cover on and replaced the screws. I placed the lower arm assembly back on and ran the dishwasher. It worked like new again.
The photos and descriptions in the parts catagories made it very easy to find the correct parts that I needed. I highly recommend Partselect to anyone who is a do-it your-selfer!

Reading the other stories really did help me get some idea of what needed to be done

I went to take the bottom front panel off and ended up dropping the screw down behind the baseboard and then found that I did not need to take the panel off. The broken end of the float was not obstructing and I was able to just drop the new float in place. I spent more time looking for a replacement screw than any thing else. Ran it a ...

I followed instructions of others that were posted. Door seal was simply removing old seal, cleaning track and pushing new seal in,making sure it was even all around. Removing the door cover to get at the Dispenser grommet was simply removing all 7 hex nut screws. Had to go out and buy the proper hex nut screwdriver . I did not remove the ... Read more wiring, just turned cover over to remove the two nuts holding the dispenser. The nut on the left was a little hard to get off, had to kind of force the socket onto the nut. Otherwise all went well and simply removed the old grommet and installed new one. Finding the right tools was the part that took the longest. I had hard water before putting in a water softener so that was probably hard on the seals plus the machine was an older model. No problems now and saved having someone come in and do a repair.
