Question about GE 24 in. GSD2120C Built-in Dishwasher

Not draining properly, leaving film, debris, & soap, draining through air gap

I have read through many of the solutions on this site, but nothing quite matches my problems. Our dishwasher was new when we moved into our newly-built home 5.5 years ago. After about 6-8 months of use, I noticed the dishwasher was leaving the granuals of the detergent tablet we were using (or some other sand-like debris others have mentioned). I went from using the hard tablets to the soft gel packs and things were better for a little bit. I recently read about the water hardness needing a different detergent that I can control the amounts, so I bought some gel detergent. I haven't used it yet, waiting to finish my soft-gel-pack detergent first. Also, our d/w drains through the air gap. I can't remember when this started, but I think it was around the year-mark. I know it shouldn't do this. We checked the drain lines and replaced the air gap & lines even though they were fine. Sometime later, I noticed that the d/w started leaving soap on the dishes during some cycles; I just rinsed them off using the sink and let them air dry (I rarely use the drying cycle). As time progressed, I noticed on the cycles that left soap was on the dishes, soap was in the tub, too. And when I would open it up after the last rinse to air dry, it sounded like a bubble bath because there was so much soap/water left. When this happens I run it through another rinse and that solves the soap issue. Then I began noticing the interior of the dishwasher was not clean when done w/washing; a film of chocolate milk or rust or soda sits on the interior. It comes off immediately w/a paper towel. Now the dishes have a film on them. It looks like hard water or like I've run the d/w without detergent - milky on glasses, cloudy on bowls/plates, and cloudy/spotty/dirty on flatware. If I use a finger, I can wipe of the cloudiness on some areas of the dishes, but not others. I even took some Goo Gone and white vinegar (not at the same time) to a bowl w/o success. Handwashing glasses w/a scrubber sponge and immediately drying helps. My father is a handyman and is going to look into this problem in the next week or so. I just thought I'd ask what he might be looking for. It seems so obvious that my problems stem from a draining problem, but why that is I don't know. Maybe there is more than one thing wrong. And by the way, I have never, ever been able to load dirty, non-pre-rinsed dishes in any dishwasher I have ever used and get clean results. Given that these newer dishwashers are supposed to clean w/o pre-rinsing, I was wondering what this was all about. Thanks!! :)

    I ALWAYS pre-rinse my dishes before loading because the couple of times I tried not doing so the results were terrible.

    I use Electrosol gel packs. I used to use Electrosol tabs but the granuals left behind on the dishes were bothersome.

    Temp is set right, I load all dishes properly, the rinse aid is full, and the spray arm is functional and never blocked. There is no visible blockage. And the airgap was replaced with no change in how it drains.

    Still need help.

I would add that you also need to check your hot water temp coming in to the dishwasher.if water is coming thru.your airgap then that part needs replacing.discontinue putting dishes in dishwash.full of food it will rectify slow drainage.also check the hardness of your water.please pre.rinse.

    i might also add that you shoul go easy on the gel type detergents.this will also help in alleviating a leaking airgap problem.

You wont get clean results if loading a dishwasher up with dirty plates, the food debris will circulate around with the water and keep reistating itself on the plates- as it may not get through the filters. try a powder wash with rinse aid topped up and the most important thing is that the salt bottle is topped up. you may also want to check that the spray arms are not all blocked up with debris.

Moved into new house with Smeg Dishwasher Model number SA 425, but no intruction manual.

I found a site that has many, many manuals for Smeg Dishwashers. None are what you asked for. Perhaps you have the wrong number.

Check the site out, maybe there is one there that will match your machine. Good Luck.

High oitch noise during wash

As motor bearings wear out, they can become quite loud when the motor runs. They wear out quickly if they frequently get wet, because the water washes away the motor bearing grease. Bearings can get wet if the spin seal is defective. Then there will also be water leaking onto the floor beneath the dishwasher. Replace the seal if it leaks (read about the main tub seal in the "It leaks" section, later).If, from beneath the dishwasher, you can see a round, plastic disc that's mounted to the top of the motor (a "slinger"), it may have broken free of the motor shaft. If so, it could be rattling around the shaft while the motor is running. If that's the problem, you need to replace the motor.
If the heater fan bearings are rusted or worn, they may squeal, or scrape loudly during the drying cycle. If this is the problem, replace the fan motor. Alternatively, the fan blade may be loose. If so, you need to replace it.

Brand new GE profile dishwasher doesn't get the dishes clean.

The problem is hard water. There is a new product out called the dishwasher filtration system. It filters the water before it enters your dishwasher. It works amazing and has a money back guarantee. You will love the way your dishes look after the first load. It is also very affordable (like 70 bucks). Go to to find out more info.

Bosch dishwasher

I had this same problem and in addition as it ran water dripped out the bottom while the dishwasher was running just before the tap light came out. Check the outlet hose is not blocked. Ours was blocked at the T junction where it met the sink outlet. Once the blockage was cleared we hit another problem - the pump kept trying to drain - even when the door was open. Found an excellent solution to that on this site. It had occured as the previous problem had casued the flood switch to be triggered. We had to tile the sihwasher back 45 degrees to fix it. Now its workig fine again.
