SOURCE: KitchenAid Dishwasher fill up with water after use

Is the water clean water or dirty water? This may sound like an ignorant question, but it can make a difference. If the water is clean water, it sounds like you could have a bad fill valve. If the dishwasher is filling with water when it is not running, chances are the fill valve is leaking. The valve is closed when the float switch senses the tub filling to a certain level. The valve is also closed when not energized by the control board during drain, drying and off cycles. However, if the valve diaphragm is not seating properly when closed, it will continue to leak by. That's probably why you don't notice it while is running and it has a chance to fill during the night when not in use. Here's what to look for: With the dishwasher off, take a towel and dry the tub as much as possible. Now, locate the fill port where the water comes in (usually on the left hand side of the tub). Watch this fill port closely for several minutes to see if water is running in. It could be as minute as a trickle or drip. If any water is coming in at all, the fill valve should be replaced. Now, another problem that can occur is when you notice dirty water staying in the tub or overflowing. This is usually caused by a bad check valve in the drain pump that's allowing water to leak back from the sink into the tub. Or, you do not have a high loop in the drain line. Here's what to look for: Check to make sure the drain line has a high loop as it leaves the dishwasher and before it gets to the drain pipe at the sink. That is, make sure the drain hose is looped above the trap in the sink and not laying under the sink somewhere. You can also try filling the sink with water and open the dishwasher door. Drain the sink to see if anything is getting fed back into dishwasher. If you see water starting to fill in the tub, chances are you could have a bad check valve. Some dishwashers have a check valve in the drain pump, while other models have the check valve located in the drain hose itself. Some don't have one at all. That's why the positioning of the drain hose can be important. Good luck to you and I hope this may help. If you determine a cause, post back with comments if you need advice on how to replace anything.

Many dishwasher have their drainlines tied into under sink disposers. If a person caps the sink drain while dishwasher is running, it can back the water back to the washer keeping dishes dirty and backing up water

SOURCE: Kenmore Ultrawash Quiet Guard 5 making buzzing/grinding noise

I have a very similar dishwasher, with a very similar problem. I fixed it by removing debris from the water evacuator pump located towards the front of the bottom of the machine (the last motor before the drain hose. In my case, grape stems had clogged it up. Once emptied, it purrs once again. NOTE: don't disassemble the motor, just flush it out, there is an o-ring gasket that is a bear to re-install.

Hi, Your dishwasher may pre-heat the water. If so, and if the water entering the dishwasher is cool, the heater may take up to half an hour to heat the water. To avoid the wait, increase the incoming water temperature before turning on the dishwasher. Do that by running the kitchen sink faucet until the water runs hot. Or increase the temperature of the hot water to the entire house at the hot water heater.
Timers don't often fail. But if every other part of the dishwasher seems to be working properly and the timer knob seems to be stuck in one place--doing one function continuously--the timer may be at fault. Dishwasher timers can't be repaired. If yours is defective, replace it.

7-8 year old KitchenAid washes dishes on bottom, but not on top


Position the spray arms in a certain position. Activate the dishwasher for a few seconds and then examine the position of the spray arms. If the upper spray arm has not moved, then either there is no water coming to the spray arm or the spray arm is clogged.

Dish washer fills and then drians without washing


If you're sure it is heating the water, then it sounds like the wash motor/pump has failed. If you've worked on washing machines and/or dish washers before, this is potentialy a DIY job - the Haynes Dishwasher manual is very good, and parts can be found on the internet.

The reason for cheking it is actually heating the water is that the symptoms sound very similar to those of a failed heater = fill, pause, empty, stop usually accompanied wth an error code. Error code will be presented by a number of flashes of a lamp, or a number on a display panle depending whch machine you've got.

BUZZING SOUND WHEN RUNNING


It sounds as if there is something in the bottom part of the dishwasher arm (it sprays the water around the bottom of the dishwasher). I would suggest that you take out the baskets and then remove and clean all of the parts that water comes out of as well as the bottom drain. If this works or does not, I would also suggest that you run an empty load using 1/4 cup vinegar. Hope this helps!

Dishwasher Repair


Ebers, you have a seperate wash and drain motor on this model. When you remove the bottom panel the drain pump will be on the right and the circulation (wash) pump will be in the rear. You are going to have to verify that you have power getting to the wash motor. Sometimes this is difficult without removing the dishwasher. The motor may have a quick connect harness going to it that you can check voltage there. If you have voltage to the motor during the wash cycle and it's not running, well, there's the problem. If no voltage, then it's probably a timer issue. Catriver..post back
