Dirty dishwasher problems

I have a 2 year old dishwasher that doesn't get the dishes very clean any more. I have noticed that the soap under the flap doesn't get all the way empty anymore. I've even ran the dishwasher empty to see if it was something in the load but the soap has the same problem. Is there a possible problem with the spray arm that I can fix? I also seam to have a film on the dishes now that wasn't there before. I cleaned all of the drain pipes and nothing was clogged. Thank you for your help.

I just put a lot of cleaning into my washer as it came with the foreclosed house. It was extreme hardwater soap scum build-up that not even Tilex could clean on every part I took apart. I used a jet sprayer in and out of the house to clean the heavy stuff. Otherwise you have to use like a toothbrush. Using the pictorial above, You can pretty much take out every starbit stainless screw you see until you get to the bottom and even expose the food chopper. When you put screws back always go in reverse til the screw drops to match the threds. Take off the back to upper water line that comes from the pump. You can pull up the black #5 one way valve by pinching it. Snap apart #1 from the lower carefully with flat screwdriver. I did not see the #12 screen which bums me out. Use lots of Limeaway and CLR to clean up. To drain while flushing water with your sink hose, take out the door latch by slipping a butter knife into it to loosen it, it will snap back on. Now you can hold the latch into the door switch to fake the machine. Everytime you cancel the wash it drains, so flush with moving fresh water. Now with a perfectly clean washer you can watch if there is a specific problem other than build up. Perhaps the oneway rubber valve is not perfect looking and thus backflow will happen. Actually we used the LimeawayCLR last after reassembly but did a hell of a jet spray job first for the heavy film. A lot of people don't realize the build up down below. The last machine I had needed bleaching every other wash and had backflow problem permanently new. In my opinion the water should be clear during the last rinse,so just before it drains check it out. Imagine if it backflowed just 3% each draining. How concentrated dirty would it be after 10 drainings? Thus it could be normal but denied and instead you have to manually flush it an extra time with or without cleaner to clean the drain pipe that rises to the sink. If that's so I like bleach but then you have to flush the bleach

Could be a a couple different issues.. Not filling with enough water or food chopper broke or food chopper filter screen clogged.

Check water level:
Run the DW and wait for the main wash to start (water will fill. pause then complete fill) The water should be no more than 1/4 inch below the heating element. If not there..replace water inlet valve.

Inspect food chopper:
Remove lower spray arm and rear water supply tube to upper spray arm. Remove torx screws that secure the sump cover. Remove the rounded cover on the left side to expose the chopper assembly. Inspect for breakage of blockage. There may be an additional plastic screen to remove first.

Hello, our Whirlpool dishwasher is about 3 years old. It is not cleaning the dishes; I don't think the arms are turning because the door is always dirty, so no water is getting that far. Also, the cycle...


Hi

If you are noticing that the dishes are not clean, then there are a few things to check for. Check the soap powder if it's kept in a dry environment. Also try replacing the powder with something like a gel or liquid. Next thing to check for is the water pressure and fill valve. Check if the water is filling in and the spray arms are throwing the water with enough pressure. Try and listen to the sound if you hear a proper spraying action sound.

If it seems as a low water pressure then check the fill valve. Now, check if dishwasher is draining the water or not. While the dishwasher is working check whether the dishwasher is draining and there is not much left out water after the cycle is complete. Try cleaning the spray arm with a soft brush. The water temperature plays a major role in cleaning of dishes. The temp should be between 125 and 150 F for dishwasher to clean the dishes. Hope this helps...

Go buy a product called Lemi-shine and run it thru your dishwasher empty to clean out any hard water and soap deposits. If you can try using only about 2 table spoons of detergent and stay clear of the premeasured tablets. Most of the dishwashers being sold are low water usage units and it is very easy to overwhelm them with soap. It also helps if the oils from the foods are still on the dishes. People tend to clean the dishes to much before loading them and then the enzymes in the detergent have nothing to attach to. Basically this leaves the soap nothing to attach to except the dishes and hence you get cloudy dishes with soap stuck all over them.

Dishes not getting clean


Check the following to address this issue.


1. No water
Make sure you get water to the dishwasher. Check to see if the water shut-off valve (located under the sink) is open. If you get water to the dishwasher, but there is still no water inside during the fill cycle, the problem might be with a faulty water valve (located at the bottom of the dishwasher, behind the kick panel, on either side), in which case replace the water valve.

2. Not enough water
If there is not enough water, the dishes would not get cleaned. This could be caused by a partially closed water shut-off valve (located under the sink), or a faulty dishwasher water valve (located at the bottom of the dishwasher, behind the kick panel, on either side).

3. Clogged spay arms
There is usually two, sometimes three spray arms in a dishwasher. Make sure there is no debris blocking the holes inside each spray arm.

4. Water temperature is too low
To get the best results, the water has to be at 120 degrees Fahrenheit when entering the dishwasher.

5. Not enough soap
If you only fill one part of the soap cup, try adding soap to both parts.

6. Smoky film on dishes and glasses
This problem occurs due to excessive calcium build up inside the dishwasher. Try cleaning you dishwasher using a dishwasher cleaner.

Dirty dishes


plugged jets, possible
more likely it is leftover food reminance left in the pump area. and on certain dishwashers it could be a swollen check valve, not allowing the evacuation of the used dirty water.
does your soap dispenser open?

If you have a water softener, you should use about half the recommended amount of soap. Never use a wet or paste detergent. As mentioned before, this unit should be under warranty.

Although I previously posted with the same problem of a film on the dishes after cleaning, I did find a section in the owner's manual which solved my problem. Lift up the rinse aid cap on the inside door - the factory setting is on "4". The rinse aid works in conjunction with your local water, which has variations in it's hardness or softness. When your dishes are streaky, lower the rinse aid setting to 1 or 2. If your dishes are spotted, raise the rinse aid setting higher.

Top rack dishes are not clean


My Whirlpool dishwasher is only 2 years old and I started having the same problems. I dismantled everything I could and washed and scrubbed the entire unit with EVERYTHING..to no avail, dirty dishes!! But I discovered a remedy! Try using Lemi-Shine for about a week with your regular wash-soap. If you are using the tablet form of soap, stop and try the powdered form. Follow the instructions on the Lemi-Shine container. You can find it just about anywhere for around $3.50. I was within "5 seconds" of replacing my 2 year old Whirlpool dishwasher when this caught my eye and I figured why not try it too? After the first wash I noticed a big difference the cleanliness of the dishes..and now it is running GREAT after 2 weeks!
