Jon Grella : Hello
Jon Grella : myHello my name is XXXXX XXXXX I am an authorized frigidaire service tech and I can help you today.
Jon Grella : you problem is common believe it or not
Jon Grella : what does the drain hose drain to? The sick drain under cabinets under the sink or to a disposal under the sink?
I can believe it. I have Googled this and found many other people having similar issues, but so far nothing has worked for me.
Jon Grella : i know for sure we can work together to fixThis. And fix it quickly and cheaply
The drain hose is connected to the sink drain pipe (no garbage disposer), about 4 inches below the sink drain itself
Jon Grella : where do you have the machine draining to?
Jon Grella : Ok great.
Jon Grella : Does the drain hose just go down then up to the sink drain
Up, then down, actually
Jon Grella : ordrain or does it get hooked to the top of the underside of the counter top under the cabinets?
Jon Grella : does it go up about a foot abovethe drain in the sink?
Yes, about a foot above the drain into the sink. There is no air vent to the countertop, just the hose.
Jon Grella : ok. Thanks. That was my next question. Does the drain have a check valve? But you just answered that. It doesn't ,and that may be the problem
Jon Grella : please do this for me.
Unless the dishwasher pump has a check valve built-in, then no
Jon Grella : It shouldn't. And actually they fail all the time. Especially if the drained water is being siphoned back into the machine. It would force the drain check valve back and allow the water to comeback into the machine.
Jon Grella : do tis for me
Jon Grella : uninstall the dish drain hose under the sink and allow the water to flow into a large bucket
Jon Grella : and let it wash and drain normally
Jon Grella : if it does then we know the drain hose installation is the problem.
how big of a bucket will I need? I have a couple 5 gallon ones, I assume that'll be big enough
Jon Grella : My guess is that the force from the drain pump is causing a syphoning issue. Which happens often. It will drain most the water out and at the end of the drain cycle it will back flow into the tub and wash with the rest of the dirty water.
Jon Grella : yes. Five gallon is good
Jon Grella : just keep an eye on it.
Jon Grella : if it runs fine with draining into the bucket install a check valve at the end of the drain hose
Jon Grella : if it doesn't help the replace the drain pump
if this does turn out to be the issue, what could I do to fix it? I've read that an air gap to the countertop is the only sure way to prevent siphoning
Jon Grella : i am sure it is the drain hose though. Just get back to me here if not and I will help you more
alright, will do. Thanks for your help so far.
Jon Grella : the check valve at the end of the drain hose will fix the syphoning. And if you want to install the air gap as well that would help
Jon Grella : your welcome.
