replace door seal

  • Difficulty: A Bit Difficult

Remove old seal by pulling out tabs one at a time.

To install new seal, I had to remove the front control panel and door panel to access the back side of all of the slots that the new seal tabs go into. Using needlenose pliers i pulled each tab individually until they were locked into place.
Replace door and control panel.

I had bought the portable dishwasher from an add in the paper and unfortunately I was unaware that they require faucet adapters and it was not given to me along with the appliance.

Detergent Cup would not open during wash cycle

This repair is very simple. Partselect.com sells a repair kit for this problem that you can use but for simplicity the entire unit is not that much more. First remove the four outside lower philips head screws on the inside of your dishwasher door. Support outer door panel while removing screws. This will remove the outer door panel to gain access to the detergent cup. Remove panel by pulling out bottom first then slightly pulling downward. You will then see the detergent cup. Unplug the two leads that are connected to the unit keeping in mind their orientation. Remove the five screws that hold the detergent cup in place. Remove the cup assembly and gasket. Clean gasket area and install new cup and gasket. Reinstall five screws (do not overtighten) and plug leads back in. To reinstall door panel position door panel at a slight angle and install top first sliding upward into place under control panel then push inward at bottom. Reinstall the four philips head screws on the inside and you are finished. The complete repair will take you less than 30 minutes.

I attempted to fix it about a year ago. Took apart the screen center stem and water spinner.
I could not find anything wrong. The machine was used very infrequently over the years. Recently my wife approached me again to fix it and knowing I didn't find any thing the first time: I took the lower panel strip off and found the translucent belt broken. I found your site matched up a belt size and ordered it. Three days later it arrived, I installed it and everything seems to work. The water drains and I'm back in business. It was so easy I was embarrassed I did not fix it the first time.

I pulled the dishwasher out & watch it complete 1 cycle : water was leaking at a through hole used to secure the upper dish rack roller to the cabinet : the nut & seal holding the roller was loose allowing water to drip down the outside of the cabinet under the insulation.: water dripped onto the belt causing belt to slip : many water marks around the pump ; as a precaution i replaced the pump bottom seal & the pump to chassis gasket : I also checked the other 3 rolles ; replaced cracked top flange & installed a more flexable water supply hose .

Right Side Door Springs Broken

  • Customer: Rock from Freeport ME

  • 10 of 12 people found this instruction helpful
With the dishwasher door open remove the 3 srews connecting the top of the dishwasher to the bottom of the kitchen counter top. Remove the lower access panel from the dishwasher and lower the dishwasher about 1/4 inch in the front and back of the dishwasher). Once you have lowered the dishwasher enough slide the dishwasher out about 6 inches (enough to gain access to the door springs on the left and right side). Remove all broken spring parts and replace using new springs. The left side of the door contained a single heavy duty spring and the right side of the door contained a heavy duty and light duty 'helper' spring. I replaced only the right side springs since the left side spring was in excellent condition. When the springs are installed slide the dishwasher back into its original position and raise the dishwasher back up to its original height using the front and back adjustment screws. Replace the 3 screws holding the top of the dishwasher secure to the bottom of the countertop. Ensure that the door opens, closes and latches smoothly and then replace the lower access panel. Job done.

Lost the faucet adapter

I had to replace the faucet in the kitchen sink orignnally. However since I use a porteable dishwasher, its hose connects to the kitchen faucet. The new faucets aerator is threaded differently than the old so that the dishwasher adapter would not screw in. I had misplaced the adappter kit that came with the dishwasher last year, so I ordered the adapter from partselect.com. when the part came a few day it was a simple as screw out the old aerator, screwing in the new adapted and then putting the modified aerator from the old faucet back in so that the dishwasher can be connected as needed.

No spray-arm motion, no drainage (broken belt)

Getting the new belt installed is a bit tricky; it seems too small to span the pump and drive pulleys.

Nevertheless, start with the belt positioned in the drive pulley and stretch it so one side fits into the slot of the pump pulley. Using both hands, crank the pulley over until the belt "rolls" into place. It may take several tries as the workspace tends to be rather tight. Good luck.

the coupling for the water hookup for my rollaway dishwasher was very badly damaged. After looking everywhere including authorized dealer and repair places, on-line at the manufactures parts website, I finally broke down and ordered the entire hose assembly. When it arrived, I simply used a toothpick to carefully remove the new gasket from the new part and put in the the old one. It took about 30 seconds and works perfectly. I paid 60 bucks for a tiny little washer, but I have an extra hose assembly if something should go wrong in the future.

Detergent Cup did not work

  • Customer: Reavis from Asheville NC
  • Difficulty: Easy

I would recommend getting the entire unit. I could have replaced the electrical component only, but the other parts were deteriorating.

I removed the 4 screws in the lower side of the door and removed the front.

I lossened the 6 screws holding the detergent cup. This was done with a small hex wrench.

I replaced the dispenser and connected the wires back onto the electrical sensor.

I put the front back on the door and tested the repair. Worked fine

I will be replacing the door gasket next. I found evidence of leakage when I removed the front of the door to replace the detergent cup.

intake water valve was stuttering causing water hammer

  • Customer: roy from cambridge MA
  • Difficulty: Easy
  • Time to Complete: 30 - 60 mins
  • Tools Required: Nutdriver, Pliers, Screw drivers, Wrench(Adjustable)

First I shut off the water intake. Then disconnected it from the valve assembly. Then disconnected the hose on the other side of the valve assembly. Then removed and replaced the valve assembly, disconnecting and re-connecting the 4 wires attached to the 2 solenoids. Then re-connected the water intake and hose. Then turned the water back on.

Then, noticing it leaking slightly, had to do it all over and include a small amount of teflon tape on the brass fitting that screwed into the valve assembly.

Phew.

belt broken, dirty water remaining in washer

  • Customer: james from smithtown NY
  • Difficulty: Really easy
  • Time to Complete: 15 - 30 mins
  • Tools Required: Socket set

I had already loosened the motor from inside the tub....so it was fairly easy to wrap the new belt around the motor/pulley system.... even though the old broken belt was 2 inches longer than the new belt(probably as a result of age and use, but the new belt is obviously the right size!) Once in place, I did have to take some care in screwing down the seal from inside being as it wanted to go more to one side than the other from the pressure of the tight belt, but all in all, it wasn't so bad. Unfortunately for me when I put the dishwasher on, I thought the dirty water problem would go away, but I soon learned that I also had a clog in the plumbing. I guess I'll never know if one thing caused the other or it was just 2 things going wrong at the same exact time. But everything is perfect now. Also, the part I ordered was at my doorstep in less than 36 hours!!!! That's fantastic!

Needed adapter to connect faucet to portable dishwasher

  • Customer: susan from muncie IN

  • 9 of 19 people found this instruction helpful
The adapter still needs another union to fit to the faucet . I have tried Ace Hardware, Lowes, Menards, Danco, Price Pfister and many online plumbing supply and hardware stores and am not able to find a union or combination of unions to fit.
I need an adapter with two 55/64-27 male ends.
