Works great
This was exactly what I was looking for. A few years ago my rinse aid cap melted & I never replaced it. I have a Kenmore dishwasher & they no longer exists in Canada. I finally took time to search the web & found a replacement. The part works perfectly! And delivery was only a few days. Wish I'd done this earlier.

broken drawer slides
open door, remove food from shelf, remove drawer,remove drawer, pry up and remove slides, instalation is reverse
Simply put the items in place...was very please with the parts. They were excactly as advertised and fit perfectly. The delivery was also very timely...thank you very much.
After de-installing the old ice-maker, I noticed that the rotating commutator was broken. Therefore, the electrical rotor was not making contact. The old "working" ice maker plus" system was easily adaptable to the new ice maker unit. The new replacement box came with plenty of spare cable adapters for multiple ice maker settings.
Cap had loosened and fell onto heater coil and melted.

Recently ordered rinse aid cap. (there was a clump of rubber material underneath the old one preventing it from screwing in; we assumed this was the lower portion of the cap which had rotted) the new cap fits but the indicator doesn't register now; also new cap has come off during the cycle once. Are we still missing a part? Namely, whatever the rubber stuff was under the cap. Thanks!
For model number DU1145XTPB3 and Serial: FS2508820
Hi Kathy,
Thank you for your question. I do not think your rinse aid cap would hinder your indicator. It sounds like you may have to replace your whole detergent dispenser assembly. I hope that helps. Good luck with your repair.

Changed heating element and thermostat and dishwasher still not heating or drying
For model number WDF520PADM5
Hello Sol, thank you for contacting us. The heating element would be the main part that creates the heat. If you have a multimeter you can measure the resistance of your heating element which should read somewhere between 15 and 30 ohms. A reading above 30 means the element is faulty and will need to be replaced. If the resistance reading is OK then check the wiring and control board for damage. Hope this helps!

Hi, my dishwasher has every once in a while after a cycle is over will just flash clean with the Green light and am unable to clear it. I recently found online a way to re set which is heated dry and normal 2x but i am wondering if there is more wrong that i should worry about. I recently ordered the cap for the dispense to maybe that will help. It seems my dishes are not getting as clean as they should and the soap not all the way breaking down. Do you think ordering the new cap will solve that issue? I have gone without one for month and just started recently having this problem more often.
For model number GU2400XTPS6
Hi Marissa,
Thank you for your question. The lights will blink on your dishwasher if your dishwasher detects an error. In this case there is a cleaning error. If the dishwasher is not cleaning the dishes correctly, you will need to check the chopper assembly, the spinner kit, the spray arm seal, the sump pump check valve, the spray arm seal, the impeller and seal kit, the heating element, the water inlet valve and the circulation pump. Also, the water may not be hot enough to dissolve the soap. Before running a cycle, turn the hot water on and let it run for a few minutes and then run a cycle and make sure there is good water pressure. If the dishes are not getting clean, the dishes may be loaded in a way that prevents all of the dishes from being cleaned. Try arranging them so that the water can reach all of them. Try varying the amount of soap used as well to see if that helps. I hope this helps. Thank you and have a great day!

Rinse agent not being dispensed...solenoid works to open the little trap door for detergent dispensing and is supposed to work again to open plunger to dispense rinse agent after final rinse is heated...rinse agent level does not go down so not getting in to wash area. rinse agent cap appears perfect, o-ring fits well and solenoid works at least to flip the detergent door. when we blow air through the outlet it comes through one of the tiny holes below the rise cap. What do you think?
For model number DU1055XTVS0
Hello Earl, Thank you for the question. This woudl be an issue with the Wax Motor on the back of the dispenser, PartSelect Number PS11750654 or the control board PartSelect Number PS11748221 not telling the dispenser to open the rinse aid. I suggest starting with the wax motor and test it to see if there is continuity and if so the board might be defective. Hope this helps!
