Hi, At the rear of the machine, bottom right there is a pump assy remove the assy & you will find a polystrene float this float is activated when the water level gets too high. Remove the pump cover & make sure the impellor spins. Refit and try on a cycle, If it is still the same you will require a new pump assy they are about £30 & they can be purchases from www.candmdomesticappliances.co.uk i have used them before & they are very good. I hope this helps.
