Realistically, a 10-year old Maytag is nearing the end of its usual life. The pump may be leaking at random times during a wash cycle. If you put 50% of the cost of a new one into repairs, it is time to thing seriously about replacement of the machine.
Check the drain hose and clear it from any debris that might be blocking the water from draining out completely. If the drain hose is clear of debris, check and clean the pump. Disconnect the machine from the power outlet before servicing for safety purposes.
Remove the rear access panel to access the pump and disconnect the wiring harness from the terminals of the drain pump and the pressure switch.
Loosen the clamps holding the drain hose and the tub hose to the pump assembly. It is a good idea to spread a towel under the pump before loosening the clamps.
Remove the hoses and rotate the pump assembly counterclockwise to release the pump assembly support legs from the keyed slot in the base of the washer. Remove the pump assembly from the washer.
Clear the pump impeller from any debris that might be causing it to work improperly. Clean the tub and the drain hose.
Reassemble the pump, the hoses, and reconnect the wires to the terminals of the pressure switch and the drain pump. Reinstall the rear access panel and run the machine.
Replace the pump (part #25001052) if water still do not drain out completely.
Remove the plastic bag covering the pressure switch. Press in the locking tabs on the back of the pressure switch and pivot the pressure switch off the pump bracket.
Grasp the pressure switch and lift the nipple of the pressure switch from the pump cap.
Install the pressure switch into the new pump assembly in reverse of the steps above.
More than likely the filter is clogged,remove the spray arm(there is a threaded cap in the center of the arm twist it to the left,then remove the # 15 or 20 torx(star shaped) screws out of the filter cover(around the edges)The filter is round and runs around the outer edge of the pump housing it lifts right out,clean it and reverse the process.It's the most common issue with not draining on this model.
It is as efficient as any dishwasher made today. It is also mechanically better than most made today. Keep it running as long as you can. Under the sink find the dishwasher drain line,using a piece of wire or string tie the DW hose up under the sink so that there is a rise in the hose from the disposal drain outlet.This way drain water will not go back down the hose.
I would remove the drainhose from sink and try draining in to a pale.if it does not then you will need to remove drain hose and clean out.Also you may need to clean out all screens in pump just remove with torx screwdriver easy when you get into it
you could go to lowes and buy an air gap to install on your sink run hose from washer comes up to air gap then down to drain if you clever could install under sink just get it high up as you can then down to drain
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
