Dishes were not cleaned properly, residue

I had removed this part several times before, it had clogged from sediment, so I had practice. That issue was resolved, but I determined the water level during the wash and rinse cycles was low, and the valve appeared to be the culprit. The trick is to remove the valve from the bracket, removing the single screw, and sliding the unit so the tangs on the bracket can be pushed to the rear and then towards the front. When you disconnect the electrical connection, then the valve can be pulled out towards the front for better access and to disconnect, if your supply hose is long enough. That makes swinging the wrench easier. Other wise it is tedious. Make sure to reapply thread tape after reconnecting the supply hose.

Lid wouldn't close on detergent dispenser

Thanks to the previous review of this part, I was able to figure out how to do the replacement myself and saving $150 on a service call. The part is super easy to replace. Remove the screws on the door, lift the outside piece of the door up and off the hinges and then unplug the old piece. I had turned off the electricity to the dishwasher to avoid getting shocked. There were 4 hex nut screws holding the part in, removed those & popped out the old part. Installed the new one, put the door back on and the screws, turned it on and no leaks. This part was so easy to replace, even for a 52 year old woman like myself!

Heater element had shorted out and began to smoke

I released the heater element from the clips on the bottom of the waaher tub. I pulled the unit out from the wall and disconnected power. There are two slip on wire terminals on each end of the heater element accessible from the back that need to be removed. One of them was badly rusted from leaking water, which had caused the short, and had to be replaced. These terminals and the crimping tool to install them are available at any home center. I removed and discarded the old plastic nuts since one of them was damaged by arching from the short circuit. Moving around to the front of the dishwasher, I removed the old heater and installed the new one. I had ordered new rubber washers, but the new heater came with them already installed. Since one of the old ones failed and caused the leak, they are a good thing to keep around as spares anyway. I installed the new nuts and tightened them to enough to ensure that the washers made a good seal. I reconnected the wire terminals to the heater, reconnected power and moved the unit back into place. The circuit opening when the heater failed caused a "call for service" error and the controller would not allow the unit to run. You will know you have this by the "CLEAN" LED flashing seven times. Clear the diagnostics by pressing the buttons for "HEATED DRY", "NORMAL", "HEATED DRY", "NORMAL" and after the controller resets, the dishwaher is ready to run. It's worked like new ever since.

Part that attaches the sprayer arm was broken.

Removed first part of the broken part from the top rack of the dishwasher from below.

Removed the screw from the bottom of the sprayer arm to release the second half of the broken part.

Threaded new part in sprayer arm and replaced screw.

Attached part to top rack of dishwasher from below. This part was difficult. (The part appeared to be a little larger than the original.) It was a two person job, one person pushing down on the rack and the second pushing upwardand inward on the part it click to click it into place. Dishwasher now works great.

Pulled everything out the front, and dug down to find a thrashed chopper assembly (like a little garbage disposal). The previous owner just tossed anything in; pop tops, plastic cutlery, etc.
Didn't pay attention to the exact installation of the chopper as I pulled it out, but, it turns out that it only goes in one way.
Used pictures and instructions I found online as a guide and didn't have any issues.
Replaced the check valve because it isn't expensive and I was in the neighborhood.

Dishwasher was making a loud noise during the wash cycle and it was getting worse with time. The bearing nearest the pump impeller was failing.

Disconnect the water supply, the drain line, and the two screws that go up into the cabinet frame, then pull the dishwasher out from under the counter. Tip the unit onto it's face and the main pump/motor is facing up. Turn off the power then unplug the electrical connector from the motor. Remove the single bolt at the base of the motor then turn the whole motor ~1/4 turn counter-clockwise. A firm pull will remove the motor/pump at this point.
The new motor/pump has a new seal. See that the arrows on the pump volute and the motor frame are lined up before inserting into the housing. The new motor/pump slides into the housing easily and a 1/4 turn clockwise will pull it in tight. Re-install the locking bolt and revers the rest of the steps to get running again.

Disconnected the power and hot water supply.
Removed mounting screws under the counter, and the lower panel screws to expose the leveling screws.

Walked the unit out to where I could reach the back side.
Disconnected the two power wires from the heater coil (slide off)
Unscrewed the plastic nuts holding the heater in place and removed the heater coil.
Replaced the heater coil and nuts.
Reversed the process above to install.

The dishwasher would not turn on

  • Customer: Mary Ellen from Fairfield, VT

Very simple. We had to remove the screws holding the metal cover on the inside of the dishwasher to access the electrical panel. Then we disconnected the wires that were connected to the fuse kit, unclipped the kit from the panel, clipped the new one on, and replaced the wires. Then all we had to do was screw the metal cover back onto the inside of the door and it worked just fine.

Dishwasher would not pump water

  • Customer: Gerald from Simsbury, CT
  • Difficulty: Easy
  • Time to Complete: 1- 2 hours
  • Tools Required: Nutdriver, Pliers, Socket set, Wrench (Adjustable)

.The easiest way to complete the impeller and chopper motor replacement is to disconnect the power, water and drain line, remove the dishwasher from the cabinet, set the washer on its back.

From this point everything is visible, pump housing, motor, etc. and it's a matter of disassembly and reassembly. Make note or a drawing of where all the wires are connected so you reconnect them in the right spots.

Reinstall water lines and power and check for leaks before replacing shield or kick plate.

Discovered through internet that it may be a bad chek-valve, Opened washer up and removed inside covers. Actually found that the chopper assembly was bent and non-functional. Ordered new assembly plus ordered a new check valve since the other was 8 years old. replaced both at the same time. Dushwasher works like new once again.

My 2 parts were delivered very quickly. We had been putting off the repair, mainly because any time you hire a capable repair man, the charge to "walk through the door"is very high. I actually thought about buying a new DW for this reason . . . Then I googleD PARTS, And was lucky to find PARTS SELECT. I was most impressed with the graph layout of the parts, which enables the buyer to actually measure the part being replaced to be sure the correct item is being ordered. The instructions were excellent, and this grandmother took care of the repair, easily.

My dishes were not being cleaned

I looked up the most common problem with this model and it was the chopper assembly. I removed everything down to this. Sure enough, mine was broken off and the screen was completely clogged with debris. It was not difficult to replace, but it did take me a few minutes to slide it in to place. Ladies, you can do this. No need to call a repairman! Look up the repair manual and see where the assembly is. I had no idea it was even there. My dishes are spotless now.
