DDW650B Dishwasher - Instructions

I removed the four screws of the filter frame exposing the check valve (piston and nut assembly) . I unscrewed the old check valve and replaced it with the new one.

Removed old rack with left hand; installed new rack with right hand.

I received my dishwasher as a hand me down, my Aunt never liked the way it cleaned. After it sitting for about 2 years i installed it in my house and found that it leaked all the time from where motor shaft went into the pump housing. After disassembling everything and scouring parts sites online, I found the parts, ordered them. 3 days later i had the parts, and the next day I had a fully functioning leak free dishwasher.

22 Year old dishwasher . . . Not worth repairing I thought so I pulled it out to dispose of it. Before I did, I went online to see if any parts were still available. . . To my surprise partselect. Com had it all! My problem was a plugged chamber located on rear wall of unit. A 20 minute repair once the new part arrived. Part arrived in 3 days but was broken inside of pkg. I called and the operator apologized profusely. . . She told me to keep the defective and explained my cc would temporarily be charged for replacement but as soon as they received a credit from supplier my credit will appear on my cc stmt. I had a replacement the following day. . . What a company!!!!

Read about somebody else with the same problem and ordered the check valve. 4 screws off, twist out old valve, twist in new valve, 4 screws back in. Now dishes are see-yourself clean.

Pulled dishwasher out. Unscrewed 4 screws holding body valve, disconnected 2 hoses and replaced valve, put machine back together in reverse order.

The hardest part was figuring out how to disassemble the door to replace the baffles and door gasket. No pictures or clues on the internet or my owners manual. I figured it out myself and the rest was a piece of cake. When the 7 screws were removed, the door liner lifted right out and new parts fit right in.

I simply detatched the broken old roller and snapped in the new one. It was very simple and I did not need any tools.

I opened the D/W door, used needle nose pliers to remove the old baffles. They come right out. I cleaned the area using paper towels and installed the new baffles. They just sit in the corners with nothing holding them. Simple job.

first, I removed the screws holding the dishwasher to the countertop.Then I removed the dishwasher from under the counter. I turned the dishwasher on it's back and loosened the three hose clamps securing the water connections to the pump assembly. I then removed the electrical plug to the motor and the screw holding the support rod to the motor. Then I worked the loosened water connections apart and removed the pump and motor assembly.
Then I removed the hose clamp and plug from one of the orifices on the new pump, and aligned all of the water connections and wiggled the new pump assembly into place. I tightened the hose clamps, Installed the new screw and support bar to the motor, and connected the electrical plug. I then turned the dishwasher upright, reconnected the power cord, water supply and drain lines and started a wash cycle to check the new system for leaks. I found that the extraneous drain solenoid that came attached to the new pump was loose and rattling, so I secured the solenoid shaft and linkage to the pump housing with electrical tape to stop the rattling.

I replaced the top filler tube. (The $65 price for the filler tube is outrageous. Glad I didn't have a service man fix it. With mark-up it would have cost me over $100 for a 3 foot plastic tube. Crazy!)

While I was add it, I replaced the corner tub baffles.

Removed the dishwasher, turned it over, removed 3 hoses, 2 clamps, 2 wires and one support. Installed new pump and reconnected. Done!

Shut off circuit breaker to dishwasher and shut off valve to dishwasher under sink.Remove bottom access panel screws on both sides of panel. Remove both screws holding dishwasher to counter.Place old mattboard strips under legs to prevent scratching floor & slide out from under counter. Use a Shopvac to remove water and spillage. Have rags and paper towels handy. Carefully disconnect wires, drain hose and water line to free dishwasher. Fold old rug runner in half to place dishwasher on, turn on side and then gently upside down on rug to access motor. Remove butterfly clamps, hose clamps, electrical connections, and support bracket. remove old motor and pump and place in box to discard. Position replacement motor and pump according to diagrams. Reconnect all clips, hoses and connections. Since replacement motor and pump is smaller, use longer support bracket from adapter kit. Return dishwasher to upright position and reconnect wiring using wirenuts, drain hose and waterline. Reposition mattboard strips under legs and slide back into place. Attach screws to counter top. Turn on power, water and do a test run to check for leakage. Replace bottom access panel. Pat yourself on the back since you've saved yourself hundreds of dollars for a repair or replacement of your dishwasher.

I made this replacement more dificult because I removed the old motor/pump earlier. Should have done it at the time I installed the new unit to be sure all hoses where installed correctly. I hooked the drain hose to the wrong port and when I started the dishwasher I found my error. Once I corrected the problem and started it again - the wash and drain cycles were perfect and there were no leaks.

Before ordering the parts I read the posts by other do it yourselfers and found them very helpful. I ordered the seal and shaft nut from Parts Select and was impressed the parts were delivered in a couple of days. I removed the two lower panels from the dishwasher to expose the leak and the shaft. I turned off the electricity at the circuit breaker box and disconnected the wiring harness to expose the area I would work on. After cleaning the water deposits from the shaft I pried off the small lock washer and removed the plastic cam from the selenoid. Next step required removal of the push on nut. This was the most difficult part of the entire procedure. It required a bit of gentle but firm pulling with pliers and a couple of screwdrivers, sacrificing the nut in the process. It was better ordering a new one originally then trying to save the old one. Having experiencing these nuts in previous work, I knew a new nut would be a cheap fix! Once off, the old seal is easy to remove. Place the new seal on the shaft as per the included instructions, place the new push on nut and reassemble as originally taken apart. (I used a socket set to push on the push on nut.) I then ran a load of dishes to make sure there was no leak before reinstalling the lower panels. I had no leak but pay close attention to placing the seal and push on nut. The seal must be in the exact place.
