SOURCE: Whirlpool dishwasher is not fully draining after cycle complete

THE PROBLEM SOUNDS TO BE WITH THE INSTALLATION OF THE DISHWASHER ITSELF. YOU NEED TO MAKE SURE YOUR DRAIN HOSE IS NOT KINKED AND ALSO THAT THE DRAIN HOSE FORMS A LOOP. IN OTHER WORDS IT SHOULD GO STRAIGHT UP BEHIND THE UNIT AND THEN DOWN INTO THE SINK OR DISPOSAL.THIS SHOULD TAKE CARE OF YOUR PROBLEM.

SOURCE: My frigidare dishwasher won't drain the dirty water

Look at repairclinic.com for your model. If the motor shows a reversing valve, that may be your culprit. Some D/Ws like Whirlpools drain by reversing the motor direction via the timer mechanism. Also look for a destroyed pump impeller/diverter that is keeping it from pumping water out. Check exit hose for obstruction, even at disposer or air gap.

SOURCE: Bosch smu2046uc doesn't drain completely (water

check the following parts for their operational value. replace any failed part.


1. Air gap / Drain hoses
If there is an air gap (located in the sink, near the faucet), check to see if it is clogged. Unscrew the top cap and see if there is anything blocking inside. Note: If there is no air gap installed, the dishwasher might not drain properly.

If the drain hose is clogged, the dishwasher would not drain. If there is an air gap installed, it is very common that a hose going from the air gap into the garbage disposer is clogged. Remove and clean the hose. Make sure to reattach the hose before starting the dishwasher.

Note: If you recently had a garbage disposer installed, it is common to overlook removing the drain plug.

2. Broken belt
Some dishwasher models use a belt to drive the pump. Replace the belt if found broken.

Note: Sometimes the belt would just come off the pump. Even though it might not be broken, it is recommended that you replace the belt, because it is probably too stretched out.

3. Pump
Some models have two impellers inside the pump - one, wash impeller, takes care of the wash cycles, the other, drain impeller, drains the water out. If the drain impeller is broken (broken blades, shaft), the dishwasher would not drain. Replace any broken pump components.

4. Drain solenoid
Some models (for example most GE dishwashers) use a drain solenoid to drain water out. Sometimes the solenoid gets stuck, preventing the water from draining out. Try to free up the solenoid. If unsuccessful, you might have to replace the pump assembly.

5. Motor
If the motor is stuck, it is sometimes possible to free it up by manually spinning the motor.

Replace the motor if defective.

6. Timer
Replace if defective (note: uncommon problem).

Hello,
After you the drain to discharge the remain water and the tub is visibly dry of water,then you open and load it do you see standing water after you have drained and know it was gone??
If that is the case what i believe your trouble is that where the dishwasher drain connects to disposer under the sink the drain hose is only leading from that nozzle downward,if that is so what is happening is the dishwasher is draining ok but backfilling whenever water runs through the sink. To fix that use a string on plastic zip tie and attach a portio of the drain hose so at one point the drain hose under the sink is higher that the nozzle and water in the sink will longer run into the hose and run upward since water is only going to drain down and wont ever rise on its own.The drain pump is powerful enough to push the drain water up that "HIGHLOOP" very easily.

Good luck i hope this has helped you to fix your dishwasher,
Gene

1 Scrape and rinse dishes before putting them in your appliance. Small food particles, grease, sauces and bones clog up the system, keeping the dishwasher from properly rinsing your dishes. You don't need to prewash the dishes but be sure to rinse off any solids.
2 Use a toothbrush to clean around the dishwasher door.
Clean around the seal and hinges of the dishwasher. This area often is forgotten and holds a good deal of bacteria and food splash. A tooth- or bottlebrush is the best way to get into the crevices.
3 Clean chunks of food out of the screen and drain at the bottom of your dishwasher, recommended The Family Handyman. If the drain is plugged, the dirty water can't be washed away and ends up back on your dishes. Nut, bean and seafood shells, bits of plastic and small dishes can lodge against the drain, keeping it from doing its job.
4 Unclog the holes in the sprayer arms. If the holes are blocked by food or soap, water cannot freely spray inside the dishwasher to thoroughly clean the dishes. Leftover food on the dishes can make the dishwasher smell.
5 Keep space around your dishes. Overloading a dishwasher keeps it from running efficiently, allowing gunk to build up around the drain and the spray arms.
6 Run your dishwasher as hot as possible to break down food and grease. The recommended temperature is 120 F.
7 Run the dishwasher with vinegar added to neutralize odor. Empty the dishwasher, place a dishwasher-safe cup filled with white vinegar on the top rack, and run a cycle at the hottest setting. If you prefer, use unsweetened lemonade powder or baking soda in place of vinegar.

Doesn't drain on final rinse cycal, leaves 1" of clean water in bottom of machine.


Make sure your drain hose is attached securely to the underside of counter/sink area. If you have a air/gap, make sure it isn't clogged. Both will cause water to backfill back into the dishwasher especially if you're garbage disposal is clogged or restricted.

if the soap/detergent isn't completely rinsing out of dispenser, it sounds like water isn't directed the top spray-arm. possible a defective vario motor; as it directs water to the water channel that supplies water to the middle and upper spray arms.

Non return valve


Has it always done this? If so it was an install issue. The tech should have put the drain above the drain with a loop to prevent backfill.

Food particles are on dishes after washing


Try adding bicarb of soda/baking soda and vinegar in the detergent dispenser. Bicarb fizzes off hardened particles and vinegar strips off grease and aids rinsing.

Dishwasher keeps tripping electric


Two things to consider....clean water or dirty water?
Clean water usually indicates the fill valve is not shutting off all the way and the fill valve is "weeping" water in all the time = new fill valve time!!
Dirty water usually is not a dishwasher problem but more of a plumbing issue. Often the sink drain that carries the sinks water outside is not fast enough and some of this sink water is backing up into the drain hose and filling up the dishwasher through the drain hose. The drain from the sink to outside needs attention as this type of a problem indicates a slow house drain for that sink.
The dishwasher drain line should be clamped to the top underneath part of the counter before entering the sink drain plumbing, this may help the water from coming back inside the dishwash
If the cycle doesn't complete, check these:

Water-heating cycle
Timer
Water-heating cycle Many dishwashers heat the wash and/or rinse water to a higher temperature, as the cycle calls for it. In these cycles, the dishwasher pauses after it has filled with water, waiting for the water to reach the pre-set temperature. What happens next, depends, as follows:

  • On some units, the pause is timed and the unit continues after the allotted time.


  • On others, the cycle can't continue until the water reaches the higher temperature. If you have this type of dishwasher and the water isn't being heated (say, because of a problem with the heating element or thermostat), after the unit stops at the heating cycle, it never continues. When you repair the heating-system problem, the "cycle problem" is fixed too.


Timer 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.

Remove the backpanel of the machine, and look if there is water at the bottom of the machine. If so, use a towel or so to dry up the water. This should solve the prob.
