Rinse and Spin Faults on Beko WMA 745 W?

The washing machine is not long past it's guarantee, and the fault started last week.
First symptoms were that it stopped after the wash cycle, drained, but didn't step on to the conditioner cycle. It then switched to pause with the rinse light flashing. Have cleaned both inlet and waste filters. The machine is filling correctly and draining when required.
This morning the fault changed to a spin fault, so ran the 19 minute spin program. The drum starts to turn then the display switches to 1 minute and stops???
Am I looking at a blockage somewhere? The impellor on the drain pump turns with a long screwdriver but feels slightly coggy against the magnets (could be normal).
Could fault be a main PCB fault?
Look forward to your replies/help.
