How can I fix my Beko WM1512S?

My BEKO Ecocare WM1512S washing machine is stopping before the washing cycle is complete. It fills and drains Ok and the drum moves round freely but there is no spin whatsoever and machine stops before the last rinse. I have manually moved the program/timer knob to the Full Spin cycle on all programs and there is no spin on any of them. Can you tell me the possible causes and fix for the problem. Thankyou.
