If your Washer fills with water but constantly drains out, there are a few possible reasons. 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.
