Some water, usually one to two cups, remaining in the bottom of the tub is normal. However, if water is covering the bottom of the tub, the dishwasher is not draining properly.
Check for paper or large objects covering or blocking the sump area in the rear of the tub.
Make sure that the right type and amount of detergent is used:
Using the wrong type or too much detergent can cause sudsing that can
prevent the dishwasher from draining. Only detergent specifically
designed for automatic dishwashers such as Electrasol®, Cascade® or Cascade Complete® should be used. If you find suds in the dishwasher.
Check disposer plug.
If a garbage disposer has been recently installed, it is possible the
disposer drain plug was not removed. The drain plug is a plastic piece
in the disposer that blocks the hole where the dishwasher hose

Installation Instructions, will be the procedure for removal of the
drain plug. You may also check with the installer.
Be sure the kitchen sink drain is not clogged.
The dishwasher typically drains into the kitchen sink drain or a
garbage disposer. If the dishwasher drains into a garbage disposer, run
the disposer to clear the drain system. Do not put hands into the garbage disposer. Serious injury could result.
You should always turn on your garbage disposer prior to running the
dishwasher to clean out any food or debris within the drain system.
Check drain hose where it connects below the sink for blockage or a kink in the hose.
New dishwashers come with a white corrugated drain hose, which should
be used. Re-using old, worn out drain hoses may promote kinking and
blockage. If it is neccessary to extend the length of the corrugated
drain hose, be sure the total length does not exceed 120 inches and the
extention used is not kinked or crushed. See your dishwasher
installation instructions for details.
Check the air gap if one is installed. It could be clogged.
An air gap (not part of the dishwasher) is usually located on top of
the sink. Some state or local plumbing codes require the use of an air
gap between the built-in dishwasher and the drain system of the home.
This plumbing device is used to prevent the possibility of back flow
into the dishwasher in the event of a clogged drain system. This item
is not a part of the dishwasher and, therefore, the dishwasher warranty
does not cover costs related to cleaning or repairing a drain air gap.
Typical air gaps are easy to inspect and clean. Be sure the dishwasher latch is in the OFF
position or unlatched prior to removal of the drain air gap cover.
Simply lift off the cover (usually chrome, could plastic) and unscrew
or unsnap (depending on type of air gap) the plastic cap below. Remove
any material that may have accumulated and replace the plastic cap and
chrome cover. This simple procedure should be followed any time the
dishwasher fails to drain properly.
Sometimes perceived "no drain" problems are not
"no drain" problems at all, but back flow of water from the sink or
some other device into the dishwasher:
If you notice dirty water building up over time in the bottom of the dishwasher and do not have an air gap,
make sure you have a high drain loop. A high drain loop is created when
the drain hose is makes a loop at least 18 inches above the floor.
Usually this is accomplished by attaching the drain hose to the
underside of the countertop. Without a high drain loop or air gap,
dirty water from the sink can flow into the dishwasher. The high drain
loop prevents back flow of water from the drain into the dishwasher if
an air gap is not installed.

Make sure the drain screen is not clogged at the bottom of the dishwasher or that you water drianline is not pinched or clogged behund the dish washer. if you are confidant in doing this you may be able to troubleshoot it. It possibly could be a water pump issue too.
There may be some food debris in the drain tube where it connects to the drain pipe. It would be easy to detach and do a visual check, and see if you can clear the clog. If that doesn't work, please don't hesitate to message back with more details!!

OK. Try these steps. -If hooked up to a food waste disposer, be sure the "knock out" is removed from the disposal inlet. -Be sure the drain hose is ELEVATED at least 32" so water cannot siphon back in the tub. -Check for a food obstruction in the drain or disposer. -Check drain hose for a kink. -Check your home's circuit breaker or fuse box. -Check that the cycle is completed. Hope this helps you!
try running it empty there is usually a drain hole in the bottom check if anything is in it or try a dish washer wash solution I bet the drain or drain line is cloged let me know if this dont work. Hows your sink draining
I first checked the water valve in the dishwasher. It was working properly. The overflow or water level sensor had become stuck in the 'high level' position, thus telling the washer that it was already full of water. I corrected that and it began working properly. As for water in the bottom of the dishwasher that didn't seem to be draining completely - I turned the timer to a point in the cycle where it would drain, making sure I turned the washer off before it cycled back to the 'fill or rinse' cycle. I think the water had accumulated because of the timing of the cycles getting out of sync with the water level in the washer.
So it sounds to me like it is your "pump" I work for an appliance parts dealer and it looks to me like the pump you need is originally part# 99002750 but then it changes to #6-917641....It runs about $57.00 and you can find this product at www.allbrandonline.com
Hope this helps! www.appliancepartsonline.net
you have a blockage somewhere probably. if the drain hose plumbed in under the sink, check there is no blockage in this area. also check the drain hose for blockages.
if all clear, the fault is probably the drain pump itself
