How to Drain a Dishwasher
Faults with the kitchen dishwasher are hard to diagnose -- there isn't much to see when you open its front. The machine's filters and waste pipe may be blocked with residue, and the dishes will still be dirty, if the dishwasher is not draining properly after the wash cycle is completed. Check the water drainage pipe at the back of the dishwasher to make sure it isn't kinked or bent. Remove the dishes and the dishwasher's sliding racks before you start draining.

Place an empty bucket directly under the wastewater pipe, located under the kitchen sink. Pull the dishwasher drainage pipe off the wastewater pipe. The drainage pipe is usually ribbed and is located at the back of the dishwasher. It simply pulls off. This will cause the water to drain out of the machine and into the bucket.
