washer drains while filling

My Whirlpool washer (2 yrs old) drains while filling. I can fill it on the rinse cycle, then advance it to wash. It then does the whole cycle just fine. Any suggestions?

[SIZE=3]Assuming the motor isn’t running during fill the water is siphoning out and can be caused by a few things.[/SIZE]

*][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][/LIST][SIZE=3] [/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 201112. [/SIZE][/LIST][SIZE=3] [/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][/LIST][SIZE=3] [/SIZE]
