I bought the same washing machine and had the same problem. My partner opened up the machine and discovered that it is weighted by a massive 1/2 ring of concrete with bolts attached to plastic shafts. The plastic shafts had sheared off so the machine kept unbalancing as well as spewing out water. Very strange design. Thankfully it is still under warranty. I am looking into putting in a claim today.
