Try pulling the drain hose out of the drain stand pipe a little. It sounds like the water is just siphoning right on through. You need a slight air gap to prevent this.

It appears that the problem was caused by "siphon action". My washer had no standpipe or any ventilation gaps that would prevent "siphon action". A standpipe intallation allows air to follow the water as it drains into the plumbing...preventing "siphon action". In addition, the standpipe also allows the tub to fill properly which than triggers the pressure switch that advances the next cycle.

After intstallation of a standpipe (1.5" or 2" diameter), which ties into the sewage plumbing, and must exceed the height of the water level of the washer, the washer worked perfect accept for one thing. When the washer experienced a spin cycle or drain cycle, a small amount of water would splash out of the top of the stand pipe. I beleive this is called "splashback". This problem was easily fixed by attaching a "standpipe end cap". The standpipe end cap is a rubber fitting that securely holds the return hose in place, prevents splashback, and has vent holes that prevent siphoning action.

Before this forum, I had no clue that the standpipe was a necessary element of a washer system. Furthermore, my washer ran pretty well, for not even having a standpipe for almost five years before it ceased to work properly...how the tub filled up without one is still a mystery. After intalling this standpipe I have not experienced any problems since than.

Thanks for the help...
