5-year old maytag dishwasher will not drain unless the control is manually turned to the drain cycle. The pump activates and expells all water efficiently.
If allowed to go thru the entire wash cycle unattended, the water from the wash cycle accumulates thru the rinse cycle, floods the floor, and remaining water is left in the pit.
Not draining the water out....
Check to make sure which style d/w you have as outlined above. The direct drive dishwashers have a drain solenoid attached to the motor and pump or a separate drain valve that must be checked with a ohm or voltmeter. The drain solenoid and valve energize and opens the drain port to allow the water to pump out. For a "no drain" problem, always start with the common stuff first...a kinked or clogged drain hose. The drain hose must be checked and cleaned out and if you have to, remove the drain hose(s) to fully check and clean them. Don't forget the drain system sometimes consists of a self cleaning bodythat also can get clogged and stop the dishwasher from draining. If your drain hose needed to be lengthened a hose connector was probably used, these hose connectors are slightly smaller than the drain hose and food bits often get clogged there, also the tail pipe piece that connects the drain hose from your d/w to the house drain is also another popular place to get a clog. On the forward/reversing style of dishwashers that won't drain, make sure the motor is reversing to drain the water out. If the motor does not reverse to drain, the motor, wires ( especially where the doors bends to open and close ) and timer will have to be checked. If the motor is reversing and running, the pump impellor inside the motor and pump assembly may be damaged and is incapable of pushing the water out to drain. If the drain solenoid or drain valve checks ok on the direct drive motor and pump, the impellor inside may also be damaged as mentioned above.
Always check the drain spout under the sink for a d/w that will not drain, also if the Air gas is leaking ( see Fig1A ) this is a clogged air gap or drain and normally not a d/w problem. These are some typical drain hook ups....if you have a drain question, may be a good idea to refer to one of the figures so we all know which style you have :-)

This will help. Thanks please keep updated.please do rate the solution positively .thank you for using fixya.
When refitting, the hose must be tightened properly. If the pump/valve does not work even with power then it must be replaced. If there is intermittent power to the drain valve/pump then the program controller unit is a suspect.
