Question about Whirlpool 24 in. DP940PWP Free-standing Dishwasher
Out dishawasher of the make above will run and drain fine up until the second (rinse?) cycle and then doesn't drain. If, at the end of the cycle, you press the cancel/drain button it will drain the standing water left from that last cycle.
This sounds like a bad timer. The timer is what tells the pump to drain at specified times. If it gets a bad contact, that timed cycle won't happen.
PS: Do you know for sure that the drain is occurring in mid-cycle? If not, you may just have an obstruction in the drain and/or anti-siphon valve (where the hose connects under the dishwasher.

FYI, for anyone else with the same symptoms. I took mine apart and found that the seal on the motor shaft failed and over time corroded the motor shaft bearing causing it to failed. I ordered full motor assembly from the parts store.

Try cleaning out the air gap. The air gap is not part of the machine, and is located on your sink. If this becomes clogged, it may cause the machine to not drain properly. Also, I know you said you checked the drain hose and cleaned as far as the filter and chopper blade, but have you checked the lower filter? There is a filter located underneath the machine that should periodically be cleaned. To check this, you need to access the machine from underneath by removing the bottom vanity cover. Hope that one of these helps!

SOURCE: My diswasher does not drain.
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. If you have checked the drain hose and can’t locate the problem, then it is an issue with the drain pump of the dishwasher. Please do rate the solution if the issue is resolved or post a comment for further assistance.
