Frigidaire stacker combo washer drains out while filling

I have a Frigidaire stacked washer/dryer combo.(Model # FEX831FS0) Last time I went to wash some clothes, it just kept filling and filling, it never started to wash. As I investigated some more, I realized that it was draining the water out at the same time it was filling! One prior post I found mentioned siphoning, if the drain hose is lower than the washer, this is not the case here. Any ideas on what would cause this?

Sill the water has got to be siphoning out assuming pump isn’t running during the fill cycle. These are the three things that will typically cause this.

[SIZE=3]The drainpipe to your house may be too low and you either need to extend the pipe up above the top of the tub or run the drain hose from your washer up high. [/SIZE]

[SIZE=3]Someone may have taped the drain hose from the washer to the drainpipe to your house to stop the water from backing up. To fix this either clean out the drainpipe to your house and remove the tape or install a siphon break, part number 76660. [/SIZE]

[SIZE=3]If the drain hose from your washer is pushed down the drainpipe too far, this will also cause the same problem. To fix it just pull it out to within about 6 inches of the end of the drainpipe. [/SIZE]
