Question about Kenmore 15121 Built-in Dishwasher

Open Question

Hi, I have a Kenmore Dishwasher with a soil separator. I have food particles on my dishes after every load. No idea what I need to do. I suspect I have to clean the soil separator somehow.... but don't know where to start. I've taken screws out of everything and can't seem to figure out how to access where the food blockage would be. Any help would be appreciated.

Dishwashers need cleaning too :) Take a look inside your dishwasher: Click here http://www.appliancepartspros.com/partsearch/model.aspx?model_id=41284 then click on PUMP AND MOTOR diagram on the left. Number 47 on that diagram is a filter. Make sure that filter is clean. Then, using a dishwasher cleaner (see below) run your dishwasher through the entire cycle on empty. This should help, post back if it doesn't. Dishwasher cleaners: 1. Vinegar - good cheap solution, if you don't mind the smell :). Dump a gallon inside an empty dishwasher tub and start up the regular wash cycle. 2. CLR - I've been told it works, but never tried myself 3. Dishwasher Magic - This stuff works pretty good. One bottle per use. http://www.appliancepartspros.com/accessories.aspx?part_id=2675393&cat=62&rdr=%2faccessories.aspx%3fcat%3d62 Hope this helps, APP tech http://www.AppliancePartsPros.com

SOURCE: Redeposits material on dishes

We had the same problem and we have managed to resolve it for the most part.  We have found that the detergent makes a huge difference.  Our experimentation found that Cascade Complete powder did the best job.  Also, our old glassware was wide at the bottom and narrow at the top which I suspect made it difficult for the spray arm to get water up there so we bought new glassware and that helped a lot too.  It still happens from time to time but it is pretty rare.

SOURCE: FOOD PARTICLES ON DISHES

Hi

If your dishwasher is cleaning poorly, check these:
Water-inlet valve Most cleaning problems are caused by the dishwasher not getting enough wash water, so the water-inlet valve is often to blame. This valve is usually at the bottom left or right of the dishwasher, behind the lower access panel. It's the device with the main water line from the house, a rubber tube to the dishwasher, and two wires attached to it.

When a water-inlet valve is defective, you may hear the sound that's usually referred to as "water hammer." If the water-inlet valve is defective, you need to completely replace it.

Internal filters Every dishwasher has some type of filter to keep large food particles and foreign objects away from the pump assembly:

  • Most modern dishwashers have self-cleaning filters that don't need any routine cleaning.

  • Some have filters in the bottom of the dishwasher that you need to periodically clean. You don't need any tools to remove the filter, and cleaning it is easy. Consult your owner's manual to determine which type you have and its maintenance requirements.

If your filter is clogged, it may be causing the cleaning problem.

Drain valve Some dishwashers have a valve (or gate) that should open only during draining. If debris lodges in the valve, it can't close properly, so water drains out during the wash cycle. Most dishwashers drain into the garbage disposer. If yours does that, listen for water flowing into the disposer during the wash cycle. If you can hear it then, the drain valve may be clogged.

Spray arms There's a spray arm at the bottom of your dishwasher--it may have a tall spray tube mounted to the center of it. There may also be a spray arm located directly beneath the upper rack of dishes and/or above the upper rack.

If debris is blocking the holes in the spray arms where the water comes out, it could cause cleaning problems. Regularly inspect each of the spray arms and clean out the holes as necessary.

Water temperature To get the best cleaning results, the water entering your dishwasher needs to be hot enough. Try running the hot water in your kitchen sink for about 30 seconds before starting the dishwasher, to pre-heat it. Also, if your dishwasher lets you select a higher wash or rinse temperature, try that to see if it helps.

To check the temperature of the hot water that comes from your kitchen faucet use a waterproof thermometer. If the water isn't 120 degrees Fahrenheit, your dishwasher may have trouble getting your dishes clean. You could increase the temperature of the hot water to the whole house--and therefore the dishwasher--by adjusting the hot water heater thermostat.

Warning! To lessen the risk of scalding, don't set the hot water heater temperature higher than 120 degrees Fahrenheit.

Detergent cup Dishwashers don't perform their best if detergent is introduced only at the beginning of a cycle, so add detergent to both parts of the cup.

If the detergent cup isn't opening, see the "The detergent cup doesn't open" section, below.

SOURCE: Kenmore elite dishwasher leaves food particles on dishes

If someone is putting dishes in the washer and obstructing the spray ams that would cause food to stay on dishes. After loading dishwasher and pushing in baskets make sure the spray arm doesnt hit any of the dishes causing them to not clean properly. If that doesnt work or is definately not your problem try removing the spray arm and seeing if it has food inside of it. Some times they get food build up in them and need to be flushed out.

SOURCE: food particles left on dishes

There are various things suggested to avaid this:
Firstly-make sure your filter is clean-empty out any old food residue and replace it nice and clean.
Secondly, rinse off loose food bits under the tap before loading into the dishwasher.
Then use the rinse program before using the main wash.
If you do all of the above you should be getting clean dishes. People often forget their filters and the muck gets back on the plates then dries on with the heat.

Glasses and frying pans not clean at end of cycle. Residue on glasses and cups,food particles on frying pans.


it's generally not a good idea to put really greasy items in a dishwasher along with relatively clean items such as glassware and plates and cutlery, as most recent good quality dishwashers come with a soil sensor that ends the wash cycle once the dishes appear clean, and all the grease from your frying pan will cause the soil sensor to take longer to detect clean water.

Crud & crumbs left on dishes


Most dishwashers have a soil separator which separates the soil from the water while it's washing. When a wash cycle is over a valve opens in the separator to allow the soil to go down the drain. If it's not working properly the washer will leave a film or food particles on the dishes.

Here are your diagrams and parts. I noticed a filter and trap which could be your problem. Make sure the water is spraying out the spray arms good.

Food particles remaining on dishes after cycle is complete.


Hi

While putting dishes in the washer and obstructing the spray ams which causes food particles to stay on dishes. After loading dishwasher and pushing in baskets ,be sure the spray arm doesnt hit any of the dishes causing them to not clean properly. If that doesnt work or is definately not your problem try removing the spray arm and seeing if it has food inside of it. Some times they get food build up in them and need to be flushed out.

However the other causes for this problem are…

Not enough water entering dishwasher (check level after fill... Should be slightly below bottom wash arm)

Water filling but draining during wash cycle. Check toward end of wash cycle but before drain. See if water level is diminished from start of wash cycle.

New 'water saver' dishwashers are notorious for having smaller water jets, and thus easier to stop-up jets. Check the jets on all wash arms to be sure they are cleared of food particles.

Another way to check the wash arms is to manually position them at specific locations, momentarily run the dishwasher for a few seconds, then open the door to inspect the location of the wash arms. Do this three or four times to eliminate the possibility of coincidence.

If the wash arms do not move from the location that you put them, the most likely cause is food particles stopping up the water jets. These jets not only clean the dishes but also the water pressure they generate turn the arms inside the dishwasher to properly distribute water pressure on the dishes.

Sometimes you can dislodge and remove food particles stuck in one of the jets with a toothpick or other small probe. Others require that you remove the arm(s) and get a little more creative. I use compressed air to clear mine, but not everyone has access to compressed air, so use whatever you can to remove the food particles.

Simply dislodging them from the water ports is usually not effective... As soon as water pressure is applied, the particles return to the jets and stop them up again. The real fix in this instance is to completely remove the food particles from the arm if you can.


Let us know if you want to know something more else please accept the suggestion.

IT is leaving food on the dishes


You do not have to prewash your dishes before loading them. In fact, by prewashing, you actually defeat the purpose of most dishwasher detergents. These detergents are activated by the grease and oils in food and work better. You should only scrape your plates of solid materials that are not recommended to go into a dishwasher (i.e., celery, popcorn kernels, tough chunks of meat, gristle, etc.).

If you are getting food particles on your dishes, this is known as "redeposition". Most commonly it is caused by food particles trapped in the filter of the main wash pump. You will need to remove the lower spray arm and access the filter screens and clean them of all debris.

If you need further assistance on how to disassemble your dishwasher to access the filter, please post back with your MODEL NUMBER. I hope this information is helpful to you.
