MDC4809PAW2 Maytag Dishwasher - Instructions

Repair man said I needed a new pump and would cost $350 to repair. This dishwasher was only 5 years old and we only use about once a week so didn't think the pump was gone. Went on this website and read some stories. this model has a mini garbage disposal with a chopper and screen which gets clogged up and prevents water from circulating. You can clean the screen without removing the dishwasher. Remove the cover plates on the bottom with 4 screws and the smaller cover plate underneath. Remove screen, clean and replace. If the chopper is broken you can order a replacement for $21. There is another story on this site with a lot more detail so I wont repeat here.

Killed the power and shut off the water. Unhooked and unplugged power, hot water and drain connections to move washer to middle of floor for easy access to all sides. Taking out the the main pump/motor assembly (the "Assembly")required taking out the flat white hot water tube that feeds the upper and middle sprayers. So, I started by taking out the two trays. Then, took out the lower, middle and upper sprayers. Then, tipped the dishwasher onto its front and disconnected the hoses and several electrical connections from the Assembly. Also, unhooked the drain pump motor and impeller from the Assembly since these are not included with the new Assembly. Took out the three sliding retainers to release the Assembly from the bottom of the dishwasher. Took a little gentle coaxing to release the seal between the Assembly and the tub bottom. Took the Assembly apart and found that the problem was the shaft bearing (ball bearings) between the motor and the impeller had rusted and subsequently failed. Therefore, buying just a new motor would have not helped. Inserted the new Assembly into place from inside the tub. Because of the tight seal, the Assembly had to be carefully placed into the tub opening and the seal gently pushed into place by working all the way around in 1 inch intervals. Took about three trips around the seal of the Assembly to ensure a tight, even fit. Otherwise, working unevenly around the perimeter will bind the Assembly and you'll have to remove it and restart. Once in and seated evenly in its place, reconnected the hoses and electrical connections. Installed the drain pump motor and impeller onto the new Assembly. Tested the unit for proper operation and leaks. Found no problems. Then re-installed the water tube, sprayers and trays inside the machine. Helps to jot down steps taken to disassemble so you retrace steps to re-assemble.

Turned off the power at the breaker, turned off the water supply, disconnected the water line, removed all three racks, pulled dishwasher out from under the counter, laid the unit on its back, removed the flat plastic water lines from inside the dishwasher, disconnected the hose and all wires (plugs) that were attached to the motor & pump assembly, removed three plastic wedges that held the pump assembly to the bottom of the dishwasher, tried to remove the motor & pump assembly from the inside of the dishwasher but it wouldn't fit through the hole, removed two parts from the motor a silver cylinder with two wires attached to it and a white plastic piece with copper wound wires and magnets in it so that it would fit, once the entire assembly was out removed one screw that holds the motor to the plastic pump assembly, twisted the motor counter clockwise the pulled it straight off, after installing the new motor I removed the silver cylinder (maybe a capacitor) that was attached to the motor leaving the two wires attached to it so that the assembly would fit through the hole in the bottom of the dishwasher, cleaned the rim of the hole and the rubber gasket on the assembly, put the assembly through the hole in the bottom of the dishwasher, installed the three wedges to hold it in place, then put it all back together. When I ran the dishwasher it was as quiet as when it was new.

Used bowls in upright position in upper shelf determining no water to upper shelf after running in rinse cycle. Added a cup of Vinegar in rinse cycle. Performed bowl test in upper rack & still no water in bowls. Dismantled inside of unit by removing both spray arms & found lower seal deteriorated & upper seal in need of replacing. Replaced seals & redid bowl test & found no water getting to top rack still. Found utube vid showing removing garbage disposal portion of unit. Requires removing screen in bottom of dishwasher. One screw attaches garbage disposal cover. Found non food items & food by broken garbage disposal. Repaired disposal, removed debri & reinstalled all components. Redid bowl test in upper shelf & bowls were overflowing!!????Dishwasher works GREAT now & can hear garbage disposal operating along with massive water being sprayed!!!

I took the valve off and actually hooked 110 volts to the vale and tried to blow through it and it would not let air pass through it. I replaced the the new valve in about 15 minutes and it works fine

I had a common issue on many dishwashers, the final drain cycle was not draining but the pump was trying to turn. Also, the drain pipe was clean. This issue caused a burning smell, like a circuit board heating up. Half plastic smell, half electrical. I bought a replacement pump, followed the pump replacement video instructions from PartsSelect, and it was replaced in under 15 minutes without any tools.

I have a new faucet so I remove the screen then I used an extender ring put on your adapter an got the washer to run.

Pulled washer out far enough to put 2x4’s under front feet. Removed front panel, I clipped wire connector and unplugged it. Pushed plastic locking lever in and twisted unit counterclockwise. Wiped inner rim and reversed above procedure to assemble.

Pull dishwasher out a few inches. Disconnect spring from plastic connector with long nose pliers. Remove connector. Replace friction sleeve. Replace connector.Reconnect spring to plastic connector. This completes repair.

Ordered a new pump (after a online diagnosis). Followed the instruction video on the website...also took the time to replace the discharge hose due to residue buildup...tested dishwasher (one cycle). Slide dishwasher back into opening....DONE. Works perfectly. THANKS

removed kick panel with screwdriver, 90 degree turn of screw. Put towel under drain pump. Disconnect drain hose by loosening spring clip with pliers to provide access to pump. released spring clip on old motor while turning counterclockwise to separate pump from drain reservoir. inspect drain reservoir from inside machine to remove any foreign objects. Installed new pump by indexing attachment flanges to notches in reservoir and turning pump clockwise until locking tab makes audible click. reattach drain hose insuring hose is contacting "stop" ribs on drain hose pipe. Run wash cycle on machine to insure there are no leaks. Re-attached kick panel.

Very simple just remove the rakes and then unscrew the covers and pop out the old chopper assembly and replace with the new and then just put all cover back and it works great.

Rather than just replacing the motor and seal, I figured it would be just as easy to replace the sump and pump assembly also. It makes sense because the extra cost is minimal and I have a completely new unit now. The repair is quite simple. Just three clips holding the sump and a few electrical connectors and the unit comes right out.

Purchased and installed new faucet attachment. It arrived quickly and very easy to attach. Thank you !

Rubber friction sleeves on each side of the door provide resistance to prevent the door from quickly opening when unlatched. Over time the friction sleeve may crack and fail. Two friction sleeves are required for repair. Install a new sleeve on each side of the dishwasher door near the spring connector at the bottom.

Open dishwasher door.

Remove the screw from the left and right bracket at top of dishwasher door opening. Brackets secure the dishwasher to the countertop.

Gently pull the dishwasher forward to expose the door spring on each side of door at bottom.

Unhook the plastic spring connector from the left door spring hook by pulling the connector slightly forward and lifting from the door spring hook. Remove the old friction sleeve if still in place by sliding over the door connection hook. Discard the old sleeve.

Insert the new friction sleeve over the door spring connector hook and push until the friction sleeve is in position completely past the spring hook. Reconnect the plastic spring connector to the door hook.

Repeat for right side of door.

Close and latch the dishwasher door. Unlatch the door. The door should remain in the nearly closed position held in place by the friction sleeves.

Slide the dishwasher back to the original position under the counter top.

Insert the screws in the top brackets to secure the dishwasher.
