Severe leaking from bottom of washer

We have a GE Hydrowave Infusion. We have recently had issues with it leaking, A LOT, during the rinse cycle. We took apart the drain pump and checked to verify it was working and clear of debris. It is still doing this on occasion. It leaks many gallons of water out. If I stop it then turn it to drain, it drains as it should throught the drain hose. What else could this be? We are wondering if it is getting stuck in between cycles. The washer is not even one year old.

Your machine may be so new it is not in the data base, but if it is less than one year old it should be covered by factory warranty. Get GE out to fix it.
