What's wrong with my Zanussi ZWX1605W?

After I washed my kitchen mat it attempts to spin but quits and continues otherwise swinging etc. Also it is sounding as if a belt is sleeping or something like that. When I found the mat still full of water I attempted to rebalance and spin, and again tried to spin completelly empty to no avail. We (my husband and I) are reasonably able mechanically and cannot afford to call a professional. Please any help out there?
