Water keep run and it overflows,dosnt start
The water level control isn't working. First, I'll describe how it's supposed to work, then give you the troubleshooting steps for a top-loading machine.
There is a port on the side of the outer tub somewhere below the low water level point. A plastic hose (usually transparent) runs from this port to the water level switch. As the water rises, it compresses the air inside the tube. This air exerts pressure on a diaphragm which operates the level switch. The trip point for the switch is set by a cam connected to the level selector knob.
Failure points: broken or leaky hose, clogged tub port, ruptured diaphragm, stuck or broken switch.
First, unplug the machine. Remove screws on the back of the control panel if it appears they hold it to the back panel of the machine. Remove screws from the front trim at the bottom of the control panel. Now you should be able to tilt the panel forward to get at the backside of the water level control.
Inspect the hose connection on the back of the water level control and repair if it appears it could be leaky (for example, hardened and loose or cracked).
You can test the switch by detaching the hose and blowing into the port if the switch is set to the lowest level setting. You should be able to trip it with moderate air pressure, not much more than you use to blow a balloon (literally several inches of water, to use a common pressure measurement scale). The best test is to attach an ohmmeter or continuity tester to the switch leads to verify operation - one terminal is common and goes to power, one terminal is normally closed and goes to the water valves, and the remaining terminal goes to the timer. However, if you can hear or feel the switch click when you blow into the port, it is probably good.
Next, gently tug on the hose where it goes down into the machine. It should be attached at the other end! Try firing some compressed air (about 5-10 psi) into the hose to blow out any clogs. Reassemble and test the machine. If it still overflows, you'll have to open the top to inspect the tub connection.
Note: I once worked on a machine that was clogged with a bacterial film inside the port. The customer used well water with only basic particle filtration. There was also bacterial buildup in the hose inlet screens, so I advised the customer to add an anti-bacterial filter to the plumbing to prevent a recurrence of the problem, and suggested doing a no-clothes soak with bleach to clear out the rest of the little beasties.
