Why won’t my dishwasher drain?

+11
Answered
The dishwasher stopped being used some time ago. It stopped draining the water out. I think it is attached to the garbage disposal or sink drain. But there was half a gallon of water in the bottom of the dishwasher we hap to dip and sponge dry. The dishwasher was turned off a couple of times after that, and the water would not drain again Does anybody have ideas on how to fix this? It’s an old dishwasher with no exposed drain lines or valves. The dishwasher is built-in. Thank you ☺️

      Thank you so much. My dishwasher has all the moving parts hidden inside the machine except the sprayer. I watched this video and it’s not helpful in my situation, but I’m looking for more videos. ☺️

      If I can get to it, I will check it. We have never pulled the dishwasher out from the cabinet to see behind it. Thank you. ☺️

    Check the float. It's on the bottom of the dishwasher, on the right. Make sure it's not clogged. If you go to the library, get a book such as Reader's Digest on home repair, it should illustrate the float and how to clear it.

    My husband installed a new garbage disposal in my sons house and then his dishwasher quit draining. I'm not sure exactly how he fixed it, but he said it had something to do with the installation on the disposal. He googled the type of disposal and turned out there was an added step that this certain type of disposal required to work with the drainage of the dishwasher. Try googling the disposal and check that it was installed properly

      I had the same issue. Its an easy fix...IF you know what to do. There is a small punch out medallion of metal that you use a screw driver to poke out. (Its only being held in by tabs so is not too hard to push out with a screw driver) This medallion must be removed or the water can not drain from your dishwasher. I bought a home with an older dishwasher. It did not however have a garbage disposal. I had the disposal installed and the repairman did not punch the medallion out despite assuring me he had. Rather then checking it, I took him at face value so assumed the old dishwasher had bit the dust. I got a great deal on a scratch & dent dishwasher but it had the same issues. Now I am assuming that it was damaged internally but that was not the issue. I finally broke down and bought a new dishwasher when the Memorial Day sales were on. When this brand new dishwasher had the same issue it was time to go back to square one. This is when we found out the punch out for the dishwasher had NEVER been removed from the new disposal and so my old dishwasher actually worked just fine. Now regarding the first question asked...if the garbage disposal is new then this could be the issue. If the dishwasher and disposal have worked together properly in the past then I am sorry that I can not add any additional information.
