WF361BVBEWR/A2 Samsung Front Load. The washer starts up and runs thru all modes until the front display shows 1 minute left. Then the pump can be hear running and running and running. The only way to stop it is turn off the machine. I cleaned out the filter and even took the pump apart to check for debris in the pump. Pump works fine. I have tried other wash modes and they all work fine, except the machine gets stuck at 1 minute and the pump stays on. I suspect the level sensor pressure switch. I have tried using an ohm meter. Seems like info on the internet suggests it operates like a single pole, double throw switch when you blow into the fitting on the switch. I cannot get that to happen. I am wondering if it is not a switch but some kind of transducer. Any help is appreciated.
Tried replacing sensor pressure switch with two new units..Neither one fixed the problem.
