Washer fills up than starts draining while in wash cycle

LF indicates a Long Fill; the washer didn't start the agitation part of the wash cycle. It either took too long to reach the needed water level or the water level pressure switch didn't send the signal to the control. Sometimes, the control board can't receive the signal. Since you are getting water into the washer, check how fast the water is coming in. The system is expecting to fill in about 8 minutes. Since the water level is determined by a difference between air and water using a hose to the pressure switch, check that the pressure switch hose isn't pinched or damages. Also make sure that there isn't a clog in the hose. You may need to replace the pressure switch assembly. Check the wires to the pressure switch and at the control board for damage or corrosion on the connections. If the wiring is good, the control board may need to be replaced if replacing the water level pressure switch doesn't solve the problem.

I hope this helps. If you need a parts list, please add a comment with the model number of the washer. (It's usually on the frame of the washer under the lid and on the back of the machine.) Since the washer is 15 years old, you may need to consider replacing it, if the control board is faulty.

WHAT IS WRONG WITH YOUR WASHING MACHINE

Most likely the water coming into the washer through the Water Inlet Valve could be siphoned out to the drain pump and out the drain hose because of an issue with the pump or plumbing. Is your washer overfilling?Is the washer detecting an overheat error? Observe carefully as to what part of the washing cycle the water is draining out. By watching the washer as it goes through its wash cycle, you can find out which part or error is causing the Washing Machine To Not Fill With Water and Keep Draining issue.

Washing Machine Will Not Fill With Water Keeps Draining How To Fix

THE WASHER IS OBVIOUSLY HAVING A PROBLEM DETECTING THE WATER LEVEL? IT DETECTS AS FULL WHEN ITS NOT AND THEN GOES INTO DRAIN CYCLE? THE FILLS AGAIN? I would suspect the water pressure switch but if it was detecting a full cycle it would sent it into wash cycle? the water inlet valve only allows the amount of water it is told to send in and does not control the amount or drain cycle. Im not sure here but Im thinking maybe the water level switch may be flawed, the one that has low-medium and high? all these can be checked with a multimeter

its suppose to start with lid down,the draining may be a faulty water level switch so this needs replaced.

Have you checked the locatio of the drain hose?

Sounds like the drain hose is lower than the top of the tub and the water is running thru the pump and out the drain hose (water seeking its own level).

raise the main drain hose to the top of the back control head. there may be a problem with the main hose being to low and the water is gravity siphoning out of the washer.make sure the washer is off when you lift the hose up but do not remove it from the wall,you should here water drain out once it has stopped draining restart you machine and it should fill to the proper level and quit then go into your wash cycle

Take the drain hose out of the drain pipe and put it into a sink to test the machine

If that works make sure that the drain hose is being allowed to breath (ie let air into the main drain pipe so that the machine does not set up a syphon).

It sounds like a siphon issue.
Check that the drain hose does a high loop before it goes into the drain pipe. (ie. drain hose loops above the water level inside the tub). Make sure the drain hose is not pushed too far down into the drain pipe. Also if the drain hose is sealed to the drain pipe this will create an airlock and a siphon will occur, allow air to enter between drain hose and drain pipe connection.
This should help you but if there is still a problem let me know and I'll try to assist you further.
Good luck!

The drain hose needs to be lifted above the high fill level in washer.The easiest way to fix this is take the drain hose (if your drain hose starts from the bottom of machine and goes up)tie or strap it to the back of the washer so it cant sag or drop down and start syphoning the water.Remember the washer will drain out the water if the drain hose is lower than the amount of water in the tub.Thats why your making sure by tieing the drain hose to the highest point before it makes it way to the drain .
