It will be a blockage in the small tube that starts at the base of the drum and connects with the pressure switch. to open up the machine, remove the soap drawer, remove the screws that become visible(you will probably require the star shaped screwdriver bits for this) open the door and you will see 3 bolts which are a size ten bolt. remove these and the entire front of the machine opens up on a hinge, to the right you will see the pressure switch. DO NOT attempt to open the pressure switch. you will see a chamber at the other end of the tube which will be blocked with gunge. clean this and your problem is solved.

Water keeps filling and overflowing when turned on but will stop when turned off, how can I fix this?


Could be a faulty fill switch. The fill switch is often an air pressure switch. As the tub fills a small internal air pressure is created which is sent to the switch via a small hose that sometimes becomes blocked or displaced.

If not it is possibly a fault with the control board.

My dishwasher Fagor fi-80 just fills continuously, till overflowing. How should it know its full? I cant see any sensors.


It uses an air bell to turn the depth of water into air pressure, then a pressure switch senses this pressure.

Down inside the wash tank, you'll see the air bell. Usually grey, a flattened rounded rectangle tapering wider towards its lower end, stuck to the side of the tank.
Take the panel off the machine, and on the dry side of the tank you'll see a little hose leading away from the bell towards the pressure switch.

Four of the more common failures....
1) Water valve stuck open. It'll keep filling even with the electricity turned off.
2) Air bell leaking. Crumbling plastic bits not unknown, this machine could be 15 years old by now.
3) Pressure switch stuck. Blowing into the switch you should hear a 'click'.
4) Most common - a build up of fat in the top of the air bell, blocking the sensing tube. With the machine empty of water, take the pipe off at the pressure switch end, and blow into it. This should dislodge any fat/debris. In extremis, slacken the nut holding the air bell to the tank, rotate the bell upright and give it a good wash out.

Miele W460 Inlet light flashing as water wont stop filling machine


Washer fills with water and overflows:

The water pressure 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, 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 switch may be defective.

You can test it with a meter and with a manual test? ( first locate it in the panel, it has a plastic clear tube hose going into it, remove that tube from its connection, now put another small tube or hose into the slot where it was and have the machine set to wash cycle with water in it. Blow into the other end of the tube.
If the machine starts to wash. the pressure switch is more than likely good
( No wash- then THE DIAPHRAGM IS BAD AND SWITCH HAS TO BE REPLACED).
Another test u can make with a multi meter is by testing the prongs individually.
# 15,16,17 (don't worry to much bout the numbers IF U GET THEM WRONG) place ur meter prongs on both out side prongs or connectors of the switch.
(where the wire plugs into) take note of wether it shows OHMS or infinity ( open or close circuit) ? Now place the meter on the left outside and the middle prong, take note agin what it shows. Now place meter prong on the right outside and the middle prong. Agin take note what reading u get. ( you should actually get a reading of infinity in 1 and a reading of continuity or ohms in the other 2? Now the tricky part. Agin place a small tube or hose into the switch and blow into it, using the meter do the same test agin on all prongs. But now keep the pressure on the switch when u blow into it, in other words use ur tongue on one end of tube to not allow air to escape. When u test it agin now one of the prongs that once read infinity should now show continuity or ohms, and 1 of the other prongs that read ohms should now read infinity or open.


The other item to check would be your water inlet valve. Check it for continuity with a multi meter it should show Ohms or a closed circuit. To test it when water is overflowing unplug the unit and see if it still overflows or continues to fill. If it stops when unplugged. Then it is not a water inlet problem but an electrical signal problem going to ur water inlet valve. Possibly from the panel or board. You can also do a live volt test to see if it is getting the full 120 current, but be sure to unplug unit before testing as this is a live test.
Also another trick to check the water valve, is to first cut the water off and remove the hoses off the back of the washer. Then one at a time point the hoses inside the washer tub and turn the water back on. If you don't have good water pressure, turn the water back off and remove the strainer that should be in one end of the hose. Inspect the strainer to see if it is stopped up, clean it and reinstall it. Now repeat this test. If you have good water pressure now, reinstall hose and your problem is fixed

By the way my advice is free cuz God is good!

LG WM2277HW washer not filling with water. All filters and water pressure checked, still not enough water to get the clothes clean. Any ideas?


PRESSURE SWITCH
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 tub. 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 inlet valve

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.

I try to start a load of laundary and it fills and keeps filling until the water is above the glass on the door. it then stops and flashes F20. i then have to shut it off and unplug it for a minute, then...


"F20" is called a No Water Detect error code. The following link explains:

http://www.fixya.com/support/r1491905-f20_error_code_whirlpool_duet_kenmore

This error code can be a tricky one to diagnose as there are several causes. In your case, however, you obviously don't have a water problem, or a drain problem. I think the problem is your pressure switch. The pressure switch is what shuts off the water source at the appropriate level. If it malfunctions, the washer will continue to fill to the point of overfilling. You should never have water above the glass as you described.

You can access the pressure switch by removing the top panel of the washer. The top panel comes off by removing the three screws holding it in place in the rear of the washer. With the screws removed, the panel will slide back, then lift off. The pressure switch will be located in the rear on the right hand side (as viewed from the front) along the interior cabinet wall. It is round, has some electrical connections and should also have a small plastic air hose attached to it.

Before assuming the pressure switch to be defective, trace the air hose to the bottom of the wash tub and ensure it is still connected. This hose is how the pressure switch detects the water level through pressure change in the tub as the water fills. If the air hose is disconnected or clogged, you can experience the same symptoms. You will need to remove the lower kick panel directly below the door inorder to see the bottom of the wash tub. Remove the panel by locating the screws under the bottom front edge. With the screws removed, the panel will drop down, then come off. The pressure switch air hose will attach to the lower right hand side of the wash tub.

If the air hose is attached at the wash tub, carefully disconnect it from the pressure switch and blow air through it. You should hear air bubbling through the residual water in the wash tub if it is not clogged. If it is clogged, carefully remove it and clean.

After verifying the air hose, you will need to refer to the troubleshooting index of your tech sheet for tips on how to properly troubleshoot and/or adjust the pressure switch. The tech sheet is located inside the washer behind the lower kick panel, or affixed to the inside of one of the interior cabinet walls. I do not have the pin numbers or measurements memorized. If the switch proves bad, replace it. If the switch is good, it may be the Central Control Unit (CCU). This is the main computer of the washer that controls all functions.

If you have any questions, or require additional assistance, please let me know. I hope you find this information helpful.

Overfilling


Have you checked the pressure switch to ensure the rubber air hose is still attached? It is common for the air hose to come loose, or develop a small hole or crack and give the same symptoms. This may save you from having to purchase a new switch. On your model washer, the switch will be located behind the load level selector knob behind the front panel. To access, follow these steps:

1. UNPLUG the unit. There are still dangerous voltages behind the front panel with the unit shut off.
2. Remove the small panel that is angled above the washer lid and just below the operator panel.
3. Remove the cover plate under the panel by removing the series of screws holding it in place.
4. At the bottom edge on each side of the operator panel is a small screw. Remove these screws and the panel should lift up slightly, then come off, exposing the components behind it.

Look for a clear rubber hose. It should be attached to the pressure switch on a small air fitting. If not, reattach the hose and place a small zip tie around it at the point where the hose fits over the air fitting. DO NOT over-tighten, as you can break the air fitting on the switch. Just make the zip tie snug enough to keep the air hose from coming loose again.

If the air hose is in place, inspect the entire length of hose for cracks or holes. If you find any holes, I would recommend replacing the hose instead of trying to seal it. That way you avoid the possiblity of tape or sealant leaking and causing the unexpected overflow again. You can find air hose at most hardware or automotive repair stores.

If the air hose doesn't seem to be your problem, check to make sure all the electric connections are attached and making good contact on the switch. If you check all the preliminary items and everything checks good, then you may assume a pressure switch malfunction. A replacement can be found at searspartsdirect.com under the "Control Panel" heading as item number 5 (part number 134493500). I hope you find this information helpful. Let me know if you require addtional assistance.

Pressure Switch or Air dome?


Does it stop filling when you hit Start/pause or do you have to shut off water supply? The air dome is the black rubber piece that is clamped to the pump housing. Usually i find that clogged not letting the pressure sw operate proper. I belive the switch has 4 wires. It has 2 contacts, one closes with a small amount of water visible in tub, hi contacts close with water much higher - even filling bottom of boot.

Water leak hotpoint wm55


Its most likely the pressure switch. Either the pressure switch is faulty or the small clear tubing connecting it to the drum has come off.. Thirdly there could be a blockage in the tubing..
The way it works is as the machine fill's with water the air that was in the drum forces up the tube, the pressure of the tube causes the switch to break therefore stopping any more water comming in.. ONCE this switch is BROKEN the the timer will move forwards.... YOu can access the pressure switch by removing the top panel (3 screws at the back) and the front panel (4 screws located near the soap draw ) then you have to remove the front panel with the door. then you can assess and resolve the situation.. The pressure switch is whitish you will see it has the clear tube attached and some wires...
