MDB6650AWS Maytag Dishwasher - Instructions

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 I installed the spray diverter,then I installed the discharge housing nut and tightened it down. Last I snapped on the spray diverter cap.

Took off bottom plate for access. Slid part that holds bottom of spring forward so I could reach it without pulling dishwasher out of position. Hooked spring to bottom attachment, then connected door spring linkage to holder that is attached to the dishwasher frame. Adjusted the tension with the tension screw and buttoned up bottom plate.

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.

Replacement parts were an exact fit. This always a concern when part numbers have been replaced with a new part number. Removed torx screws from door. Separated door shell, unplugged two micro switches, removed old latch and handle, replaced with new. Previous on line advice was helpful, but repair easy and quick.

The only tricky part was fixed by reading another post on this website -- removing the plastic endcaps on the steel sliding brackets. This is a necessary step before replacing the wheels because the bracket needs to slide between two fully installed wheels.

To remove the endcaps, you must push the flat end of the endcap (the side of the endcap facing you) sideways toward from the dish carriage, with your thumb. Once that slides sideways, the entire endcap can be easily pulled from the bracket. Not much force is required for either step in removing the endcap. If you look closely at the endcap, there is an arrow to show the direction in which to slide the flat portion.

The wheel can be bumped onto the wheel axle by placing a wooden block against the outside of the wheel and then applying a gentle tap of a hammer to the block. Use a flashlight to make sure the wheel hub rests against the washer tub sidewall.

Most difficult was figuring out how to release the top rack...just flip the end pieces to the side and out they come. Next was removing and reinserting the spray head in the bottom rack...just twist and take out then align and twist into place in the new rack.

1. Removed the torx screws around the metal liner
2. Pulled back the metal liner being careful not to disturb the connected wires
3. Pushed scissors into the latch actuator (part that pushes into the the catch on the dishwasher cabinet) until it sprung into position to simulate closure - you can't get the handle on easily without doing this.
4. Placed the end tab of one side of the handle into the slot on the side of the latch actuator.
5. Applied pressure on the other side until it snapped into place.
6. Pulled on the handle to release the catch.
7. Replaced the torx screws.
8. Works perfectly!! (until it breaks again)

I first removed the washer arm. Be careful because it is screwed on with the large center plastic piece with right hand thread. That allowed me to take the arm and disc off.

Next I took 6 screws loose with the allen wrench. This allowed me to get to the filter ring. I removed it and that allowed me to get to the three screws holding the discharge. I used a 5/16th socket to remove them.

A plastic disc that was part of the upper pump came loose and caused the noise. I replaced the upper discharge housing (with upper pump as part of it) and upper discharge housing gasket and reversed the order to reassemble.

The exploded diagram was a terrific help

Figured out that the only thing that could be causing this was a bad inlet valve. Repair was really easy. Didn't even have to pull machine out from under cabinet. First removed kick plate. Then placed towel under the old valve. Undid the power connections and water lines (in and out). removed the to screws holding the valve to the body of the washer. With the valve free, removed the brass elbow and installed it on the new valve. Reinstalled the valve and all connections. Works like a charm.

Took the replacment rack out of the box and found that it was the proper one. Had to rotate out the water director tower from the orignal rack and install it in new rack which took a few seconds to figure out . it was time to discard the ailing rack! Apparently the dish soap can attack the rack materia if there is any metal exposed and rot it out like rust so when this happens time for a new one. Otherwise there are no pins to support the bowls and plates in the lower section.

I took the bottom rack out of the dishwasher. I then took the filter guard and bottom spray arm out. Then I took the screws out of the filter guard to get to the rinse arm. I took the filter guard off, took the old rinse arm out and put in the new one. Have to make sure it is completely resting inside there. Then I put the filter guard back on. Put the screws back into the filter guard, put the two arm seals down around the rinse arm, put the bottom arm spray with guard back into the notches, put the screw top on so it can screw back in and the dishwasher is ready to go. Just make sure that you don't have a lot of soap built up, it will not clean the dishes right nor will the spray arms move. I had to call my appliance person out, and I have so much built up from soap, that I had to order a new filter guard and top and bottom spray jets. I now know to switch back to powder or liquid soap, because the tablets make a huge built up of soap... I have these parts on order now. In the meantime, I am cleaning out the jets with dishwasher magic and vinegar while I am waiting for my new parts. I now know how to put things back together so when I have this happen again I will know how to do it to save me the 63.00 office call and parts. I am happy that I know where to get my parts when I need them or break them by accident on trying to put my dishwasher back together again. Thanks.

I did not move the dishwasher out. It is a fairly tight space underneath, but the water inlet valve is located toward the front, so it wasn't too bad. The steps were:

1) unplug the power and turn off the water to the dishwasher.
2) remove the 2 wire connectors.
3) use the nutdriver to remove the 2 screws that hold the valve to the side of the dishwasher.
4) use a wrench (5/8") to remove the nut where the water goes into the valve. This takes some patience since you can't turn the wrench very far in the tight space.
5) remove the water outlet hose by using pliers to squeeze together the clamp and move it up the hose. Then twist the valve to free the hose and remove it from the valve. The nibs on the clamp are small and take a little time to get them squeezed together. If the hose has been on there a long time, you will have to twist the valve a few times to free it up.
6) now you will have to remove the sleeve that the nut was screwed onto. I had to take the valve to my vise to hold it. Then it wasn't too hard to remove.
7) use teflon tape before you reassemble. Just go in the reverse order.
8) hope there isn't a leak. Mine didn't.

The new water inlet valve seems to have fixed the problem!

Took off old, snapped in new.

It takes about 5 min. to disassembled the lower jet system. As you disassemble, make sure you clean all the filters, and asses the integrity of the filters. If they are broken, you need to replace. Once you get to the impeller, you know it is broken because the lower part is loose. To replace you need to firmly hold the impeller as you unscrew the top screw. If the housing gasket is broken or too loose, replace. Otherwise you will have leak. Refer to your models diagram for proper assembly.
