Timed out on drain cycle, basically you either have an outlet blockage or something is trapped in the pump, you can check the pump by opening the bottom right flap on the front panel,manually emptying the w/m and checking the pump filter for coins etc. Also, check the outlet isn't blocked.
Good Luck.
