Many dishwashers use a drain valve with an electric solenoid. When electricity flows to the solenoid, the valve opens and diverts the water to the drain. Sometimes the solenoid, or the diverting lever, sticks and prevents the dishwasher from draining or filling properly. Try to free up the solenoid to lubricate the lever. Otherwise, you may have to replace the solenoid or pump assembly. With these systems, the motor always rotates in one direction. When it's energized, the drain valve diverts the water.if there is problem with above process anywhere some water will be left out.-------

Hi
Thanks
for using FixYa. Dishwasher not draining properly or not draining at all issues
can arise due to different reasons. Usually, these issues are related to
kinked hoses, knocked out disposer unit (if connected with the dishwasher drain
hose) & clogged drain pump & filter. Also note that dishwashers do not
drain completely after a finished cycle and this is normal. Dishwashers are
designed to leave some water in the unit to ensure that the heating element
doesn’t overheat. If you suddenly begin to experience a large amount of water
being retained in your dishwasher, you have a problem. Some of the most common
reasons include that the drain hose isn’t working properly, the drain pump
isn’t working correctly, or possibly there is a plumbing problem in your home’s
drain lines.
First
check whether the drain is not clogged or blocked and the line is not kinked.
Check all the hoses for blockages & also clean the air gap. Has the
disposer been replaced recently? If so, chances are the knockout is still in place.
Simply remove the drain hose from the disposer, and knock out the plug. If the
disposer has not been replaced, try removing the drain hose from the disposer
and use a wet-dry vacuum (prepared for water, of course) to **** any water (and
hopefully anything else) from the drain line. Then reconnect the hose, and test
the unit. If you have checked the air gap and the drain hose and can’t locate
the problem, then it is an issue with the drain pump of the dishwasher.
Please do
accept the solution if the issue is resolved or else revert for further
assistance.
Thanks

Most of the time its a bad piston valve.inside and in the back of the dishwasher there is a filter with four screws holding it in,remove them and lift it out. in the middle is a hole and a valve ***. that you can unscrew. remove it and look at it is the rubber rotted out? if so replace it. what happens is when it goes into rinse cycles the worn out valve allows water to come back into the machine.good luck!

My GE Triton dishwasher has a drainage issue. After any of the "washing" cycles, the drain pump runs for 30-35 seconds and the water in the tub is removed. However, after the "rinse cycle" the drain pump only runs for 2-4 seconds and 2 inches or so of water is left in the tub when the cylce is complete. I have cleaned all the filters and checked the high drain for clogs. What else can I do? Is there a timer for the pump that may be amlfunctioning during the rinse cycle? Thank you in advance for your help.
The tech that came out said my dishwasher has two (2) pumps and the one that controls the rinse cycle drain was malfunctioning. They wanted $600 to fix it....so I bought a new one. Thanks for your help.
