Question about Frigidaire FEX831C Stack Electric Laundry Center
You may have one of several parts malfunctioning. If the water level sensor isn't working or the water solenoid sticks, this will happen. Let it fill and when it is at a point where it should shut off, check for voltage at the water solenoid (should be where the hoses hook up) If there is voltage there, the sensor is suspect. The sensor is behind the knob or buttons that get set for the load size. There is a tube running down into the tub from the sensor. That could be blocked. Otherwise, the sensor itself is probably your best bet.

The load level sw called the ( pressure sw ) is the control for this / and has probably gone bad / other caused would be the water valve and if this were the case only to stop it is turning the tap's off / in some cases the pressure sw tube to the sw is full of soap / hard water deposits ect . and cleaning the tube is the correction .. you can use a 9 wates saftey valve at the tap's ( when water gets on floor it shuts off the inlet taps / but at this time there is 16 gal water in tub that could still leak out . I would replace the pressure sw after cking the air tube to in ..mm

If it fills with water and starts the cycle and
the water keeps running in then your water inlet valve on the back where the
water supply comes in is sticking. It needs replacing.
Your pressure switch stops the water and allows it to start the next cycle. It's a switch either in the control panel or at the top of the tub with a small tube connected to it which goes down between the inner and outer tube. As the water level increases the air in the tube is compressed until there is enough pressure to make the switch stopping the water from filling. This tube can get clogged and the switch won't work. Remove the tube and clean it out. Blowing on the tube when it's still connected to the switch will make the switch if it's working and clear.

Water Level Switch/Air Tube
The water level switch (aka pressure switch) senses the water level in the wash tub. It does this through a plastic tube which runs from the switch in the control console down to the side of the outer tub, near the bottom . The tube is filled with air. As water enters the tub it also enters the tube. As water climbs inside the tube, it pushes on the air trapped inside and increases the air pressure. When the air pressure reaches a certain level, it triggers the switch.
A defective pressure switch can interfere with the cycles. It can also result in underfilling or overfilling of the tub.
The switch routes current from the timer control to the temperature switch and the water inlet valve when the tub needs to be filled. Once full, the pressure switch cuts the current and reroutes it to the motor on the timer control to continue the cycle.
Inspect the air tube for kinks, breaks or damage. The tube should also be free of water. The tubing should be securely connected to the bottom of the outer tub and to the bottom of the water level switch.
The water level switch has three connectors. Label and disconnect the wires from the switch. Test the switch for continuity using a multitester. Set the multitester to the ohms setting X1. It will be necessary to test each of the three possible pairs. For example, test pairs 1 & 2, 1 & 3 and 2 & 3.
Place a probe on two terminals and note the reading. Now move one of the probes to the other terminal and note the reading. Finally test the third pair and note the reading. The multitester should display a reading of infinity or continuity for each test. In this test two of the pairs should read infinity and one should read near zero resistance (continuity).
Now blow gently into the air pressure connection and retest. It should click and you must maintain the air pressure while testing. For the two pairs that read infinity one should now show good continuity. The pair that previously gave of reading of continuity should now give a reading of infinity.
If the switch fails either of these tests, it should be replaced.
