Check that the drain hose is installed properly, according to the instructions included with your machine, if the washer will not spin after the first drain cycle.
Pull the drain hose out and inspect it for blockages. Remove the drain hose from the machine and look through it. Remove any clogs with a clothes hanger.
Press the rinse/hold button to see if the machine is paused.
Remove the clothes load from the washer and try to wash again with a smaller load. If the load is too large or off balance, the machine may not drain properly.
Check the lid switch on the machine and see if it is broken or bent. The lid switch give the washer a signal that the machine is closed.
Call a service professional if the issue continues after you've tried all of these troubleshooting methods..
