I was able to elevate the line going into the garbage disposal as much as possible. There actually was a little opening at the top of the thin backing, or backside, of the cabinets. So, the dishwasher drainage hose was actually going upward and through a small hole in the back of the cabinet, then, just about straight over to the garbage disposal. So, I pulled a little bit more of the slack that was in the hose through the small hole in the back, and used a heavier duty plastic fastener to attach it to the primary (sink) drainage pipe going out of the house. The dishwasher drainage line now goes down and has to ascend back upward to the garbage disposal. Now, I have more of a loop in the line going into the garbage disposal from the dishwasher. I have run the dishwasher cycle twice and it looks alot better. Still not totally clear, but, I might be out of the woods. I think the builder probably put in the cheapest dishwasher he could find to save a few dollars. Maybe I have bought myself another year, at least, on getting some use out of what I have?! Thank you very much Big Jon for your assistance with this. It is very much appreciated. By the way, I had no luck in finding the installation manual for a GE Nautilis dishwasher, the GSD 2200. User manuals are easy to find, but installation manuals? - no luck. If you find one, I'd love to have a copy. Thanks again Jon.

We don't have an air gap - when we did have one in our kitchen (before remodel), we would also have backup sometimes from the dishwasher....I don't like how icky the mineral build-up gets around those air gaps and I didn't want a hole in the graniite for the metal airgap. Our installer looped to the top of the underneath part of the counter the drain from the dishwasher into the garbage disposal....the kitchen is 3 years old and there is absolutely no back-up ever, no noise when the dishwasher drains - it is absolutely perfect....I will never have another one of those noisy, messy, ugly silver thingies again.

Now because it never closed you need to run straight bleach through it...like 1/2 cup in the water. You might have gunk built up on the check valve not allowing it to close since it probably never really sealed like ti should have. After doing that and it's still does it I would question the check valve.

Now tell me Jon, where exactly is the check valve located? As part of the disposal or part of the dishwasher? In other words, which end of the hose? I don't have an installation manual or schematic picture of the set-up, plus, this is only the third dishwasher I've ever had not to mention the first I've tried to work on.

Should be at the DW side of the hose. If you take the front bottom panels off where the hose connects to will have the check valve in it. Without knowing a model or brand that's about as close as I can get. The height of the water helps force the valve shut......If it's level the only for being applied is the height of the hose it's self.....if it's 20 inches high you have the total weight of that water forcing down on the check valve.

Pretty rare for one to go bad IMO but not having the high loop may have lead to it if it's truly bad.

I have a GSD 2200 - General Electric dishwasher. The hose has always been at a high level because it runs from the bottom of the washer through that hole in the back of the cabinets. I just added an extra downward loop, so to speake, before it went into the garbage disposal. So, I am not sure it really helped. Maybe my checkvalve is bad? I guess I could always call the customer support number in the manual but I need a installation manual to try and do it myself.

Default Check valves

Which check valve do you recommend? Looks like two different ones? Will either one work. Doesn't look like they attach to the hose but maybe they do?

Probably inside a housing you may have to take it apart to see which one for sure. I never worked on one of those models.

Before all that thought make sure the GD is clean and clear also. Put about 6-10 cubes of ice in it with a little bleach and dish soap and turn it on then run hot water till it goes down.
