Summary: The pump housing breaks. There are a ton of reviews I am seeing on other similar models and they describe the issue over and over again. Stay away from this until the model no longer has the pump attached to the washer drum.
Summary: I bought the first Samsung washer model WA456 in Aug 2012. Water would spin up over the drum and onto the floor in the Pure Cycle. This machine was replaced with the same model. Now after having the second machine 10 months the pump cover broke, caused the pump motor to fall and this disconnected the water drainage hose. Water was pumped all over the floor. My hardwood floors are damaged and water also poured out of the ceiling light fixture on my lower level.
