Check the power source to the washer and make sure that the washer is plugged in. If a fuse has blown or a circuit breaker has tripped, replace or reset it. If the fuse blows or the circuit breaker trips again, call an electrician to find out if the problem is in your wiring.
Open the lid of a top-loading washer and see if the load has shifted to one side of the washer. If the load is unbalanced, the drum can't spin and drain. Redistribute the clothes in the drum and close the lid. Restart the washer.
Examine the drain hose; look for kinks. Unkink the hose and reinsert it into the drain according to the manufacturer's instructions. Restart the washer.
Find the end of the drain hose and examine how it is inserted into the drain. There must be an "air gap" between the hose and the drain for the washing machine to drain properly. If the hose is stuffed down into the drain, a washer cannot empty itself. Adjust the hose and restart the washer.
Make sure the end of the drain hose that goes into the drain is bent into an inverted U-shape just before it enters the drain. If it is not, put the drain hose into the correct shape and use cable ties to hold it in place.
Check the household drain to find out if it is clogged. You can do this by turning on faucets in the house and wait to see if the sinks and tub drain. If several of your drains are running slowly or not at all, your main household drain probably is clogged. If the other fixtures are draining well, the washing machine drain may need to be cleaned out.
