How to fix my Giantex/Costway twin washer?

Recently purchased, was supposed to be brand new. During the first wash cycle it worked perfectly but had faint burning smell, which I thought may have been because it was being used for the first time. Second time washing a light load the spin cycle was going when I switched the other compartment to drain. Suddenly both motors stop and it won't work anymore. I'm waiting for a reply from the seller. In the meantime has anyone else experienced this problem and how was it fixed?
