I'm sorry to hear that you're having trouble with your GTW720BSN1WS washer. There could be several reasons why it won't turn on. Here are a few things you can check:
Power supply: Ensure that the washer is properly plugged into a working power outlet. Check the circuit breaker or fuse box to see if the circuit has tripped or the fuse has blown.
Control panel: Make sure the control panel is functioning correctly. Check if any buttons are stuck or unresponsive. If the control panel is not working properly, it may need to be repaired or replaced.
Door/lid switch: Front-loading washers have a door switch, while top-loading washers have a lid switch. These switches are designed to prevent the washer from starting when the door or lid is open. Ensure that the door or lid is closed properly, as a faulty switch can prevent the washer from turning on.
Water supply: Some washers require a sufficient water supply to operate. Check that the water supply valves are turned on and that the water hoses are properly connected and not kinked or blocked.
Child lock: Some washers have a child lock feature that can prevent the appliance from turning on. Check the user manual to see if your model has this feature and learn how to disable it.
If you've checked all of these potential issues and the washer still won't turn on, it may be a more significant problem that requires professional assistance. In that case, I recommend reaching out to the manufacturer's customer support or contacting a qualified appliance repair technician to diagnose and fix the problem.
