Ge washer overflows but stops overflowing when it is turned off - wondering if it is worth paying a repair person or if we should just scrap the washer and get a new one.

On this model of washer you have 4 separate components that could cause overflowing. The water valve, pressure switch, pressure switch hose & the air dome. If you have to turn the water off to prevent overflowing, I would recommend replacing the water valve. If you can turn the timer off & the water stops overflowing, I would recommend checking the pressure switch, hose & air dome.

This is usually the pressure switch. Also you could check the water inlet valve if water is still flowing in the machine after it stops. There are free videos on testing these components at www.appliancehelponline.com/servicemanual.html
You can also punch in your model # for diagrams

you need to clean the pressure swith hose on the lft side of tub small rubber hose stop use in liqid soap

the transmition is bad,it does not hold the inner tube in wash cycle.as the ajitator work's the inner tube turns at the sam time,the inner tube turns faster and faster and a cyclone efect happens and the water go's out the overflow tube.the cost of repair would exceed the worth of the unit.

Check to see if the washer inner tub is spinning during the agitation. If it is it is causing the water to spin up and over the side during the wash cyle. Bad brake package and usually not worth repairing. You can also have too much high sudsing soap in your washer, causing it to over flow out the safety overflow pipe. Good Luck Appliance Specialists.

I replace the inlet water value. The part was less than $40.00 and took about 30 minutes to do.

He probably disconnected the water level sensor when replacing the belt or the timer is dead.
Check for any unconnected sensor or check if the main program button is turning propely..
cheers

older machine would have been easier to fix ..remove front ck small hose to tub left side remove hose and clean crud from end as much as possible if still overflowing replace water level control..new machine may be timer or lid switch not closing properly remove front to acess lid switch on right side

Hello,

If you unplug the machine and the water still comes in, you have a bad Water Inlet Valve. If when you turn the machine on at in overfills and you can stop the water by turning off the washer timer then you have one of a couple possible issues.

First, you pressure sensing tube could be clogged
Second, you just plain have a defective pressure sensing switch.

If you have anymore questions, feel free to comment back.

Thank you

sounds like you are right the water inlet solenoid on the hot side is sticking remove the hoses and clean th escreen out and the valve try agin with a fill on hot to see if it stops on a small load if not replace the water inlet valve
