Washer want stop filling up with water I change the water inlet valve but my water level knob want control the amount of water going into the machine

Did you check the gauze strainer in the water connector.

To test for voltage, use your multimeter. Turn the machine on and set a cycle, then carefully use the probes to check for voltage.

The Water Inlet Valve on your washing machine is used to fill the tub with cold, warm or hot water for the wash and rinse cycles. The valve is operated by electric solenoids that are controlled by the timer or electronic control board and the water level control/water level selector switch or pressure switch. If your washer continues to fill during a cycle, the water inlet valve could be at fault. To verify that the valve is at fault, unplug the washer when the symptom occurs. If the washer continues to fill, then the water inlet valve is defective. If the washer stops filling, then the problem is related to the electrical circuit that controls the valve. The water level switch is a pressure activated switch that is used to determine the correct water level in the tub. This part is normally located behind the control panel and will have a hose or air dome tube that connects it to the tub. On washers that use an electronic control, this switch may be located at the sump area below the tub. As the water fills in the tub it will compress the air in the tube and push against a diaphragm inside the switch. The switch will control the water inlet valve and turn the valve off at the correct water level. If the tube has a leak or is plugged, not enough pressure may be created to activate the switch and the washer may overfill. If the switch is defective it may also cause the machine to overfill.
To determine if the switch is bad, you should first eliminate the air dome hose as a problem. Look for signs of cracks or worn areas on the hose. Remove the hose and submerge in water. Seal one end and blow air into the other end and look for bubbles. Check for an obstruction in the hose as well. If the air dome hose appears to be ok, then the water level pressure switch may be defective. Inspect the switch for signs of a mechanical defect or debris plugging the hole in the inlet nipple. To test the switch contacts for continuity with a multi-meter, you will need to apply the proper amount of air pressure to the air dome tube and then look for the switch to go open circuit at that level. The easiest way to do this is to start the washer and allow it to fill to the normal level and then remove the power cord. Locate the pressure switch and remove the wires from the correct terminals and then perform the continuity test. There should be infinite resistance or an "open circuit" when the water level is correct. If not, then the switch is defectiv

Easy check for water filling problem like yours. Unplug the power and see if water still flows into machine. If yes----your inlet valve on the washer is stuck open and needs replaced. It is the part on the washer back where your fill hoses attach to. If the water is flowing into the machine while plugged in and it stops when unplugged, you have something in the control panel sending power to that inlet valve even when the machine is off. You would now need to find out where the power is coming from. If its an electronic control washer, the main board may need replaced.

check level switch and tubing. make sure working and not damaged or defective.. The washer cannot tell how much water is in tub if level switch not reading correctly. The inlet valve only lets the water in the washer cannot regulate the level.

replace level indicator in washer

Hi

If the washer won't fill you'll need to check for the water inlet hose, the water inlet valve and the pressure/water level switch assembly. Inspect the inlet hose coming to the washer for any blockages. If the hose is not clogged then check the water inlet valve for any clogs, if the water will not even fill for few seconds then certainly the water inlet valve is bad and should be replaced. You can also use a multimeter to check continuity on inlet valve. If you don't get any value on the multimeter then you'll need to replace the water inlet valve assembly. However, if the valve is fine then the pressure/water level switch assembly should be replaced. Hope this helps... Please post back if you need more information.

your fill switch is either bad or "gllitched" and the timer cannot move until this switch senses the right amount of water for the load unless its an electronically sensed water/load capacity filled machine,when it starts,the water fills the unit and the pressure switch shuts the water fill off when at selected water level and powers the timer to continue the wash cycle,it works off a "bellows" on air pressure to change a switch by air pressure to operate the machine when full of water

NF error for the FAV6800AW machine an many others = a no water fill error. The Control Board has not sensed from the pressure switch the correct water fill level after X amount of time.

Do you hear water flowing into the washer for the Cold or Hot water fill cycle? If not you could have clogged water inlet valve screens. I would shut off the Hot/Cold water supplies to the machine and pull the supply hoses off the back of the machine and inspect the water supply inlet screens. They look like this;



You could have a failed water valve solenoid. Do you hear the water valve solenoids go clunk at the start of the water fill cycle?


I assume your machine is a FAV6800AW or FAV9800AW here are some links for reference if you want to troubleshoot the issue; The Service Manual for reference. Sears Parts Direct for reference.

Post back if you have questions

If it does not agitate at all, then it is either the motor, the clutch/motor control or the agitator.

If the machine start agitating only when you advance manually the control knob, and at the same time is overfilling, that is probably because of the problem with the water inlet valve, or the water level switch, and that is also cusing the cycle to stop.

See:It's overfilling

You either have a defective pressure switch or water inlet valve. Start to fill the machine with warm water so that both solenoids on the water inlet valve (hot and cold) are activated. After about 30-60 seconds, push the timer knob in to stop water flow. If the water continues to flow, replace the water inlet valve. If this is the case, it may take a few times of starting and stopping water flow to allow solenoid to heat up and become symptomatic. If water flow stops abruptly each time knob is pushed in, you most likely have a defective pressure switch (water level switch).
