If the washer’s power cord is loose in the power outlet, it can result in the machine stopping during a wash cycle. The power cord must be secure in a grounded three-prong outlet. Give the power cord a push to confirm it is securely in the wall outlet. If it was not loose, the cause of your problem is something else.
If your power has gone out, blinked or gotten a short, it can cause the washer to stop running. Usually this happens because a fuse blows or a circuit breaker trips. Checking out your household fuse box or breaker box can confirm if this is the cause of the washer stopping. If so, reset the breaker or replace the fuse.
Unplug any extension cords you have in use with the washer. Using an extension cord with the washer is not recommended by the manufacturer. In fact, it can cause the machine to stop during the cycle. If you are using an extension cord, plug the washer directly into a power outlet instead.
If your washer continues to stop and blow a fuse or trip a breaker, the cause of your problem may be a household electrical one. It is also possible that the wall outlet for your washer is no longer working properly, also a household electrical issue. Test the wall outlet by plugging in something else to see if it works. If it does not, you have a problem with the outlet. If you suspect an electrical problem may be to blame for the washer stopping, consult an electrician.
