Turn the washer off and unplug it.
Extend a garden hose from the spigot outside, through the window and into the washer. Push it all the way to the bottom of the washer.
Turn the water on for a minute, just until the water flows into the washer. Turn it off and detach the hose from the spigot. Allow the water to siphon into the flowerbeds or onto the lawn.
Remove the wet clothing. Continue siphoning the standing water out of the washer. Siphoning the water may take an hour or more, depending on the size of the garden hose and the drop, or distance, between the level of the washer and the far end of the hose.
Pull the washer out from the wall. Turn the hot and cold water faucets off, and then detach the hoses. Take the drain hose out of the drain pipe, and place the end in a bucket to drain the rest of the water from the pump.
Check the washer's belt. If the belt is broken or the pump is frozen, remove and replace the broken part or call the appliance repairman.
Take the wet clothes to the laundromat to rewash and dry them.
