Hi Ian, F2 on this dishwasher is a flood fault.Take off the front metal plate and look inside.The base will be full of water. drain off the water.Look at the motor hose to the sump at the top.It splits.As you cannot buy the hose,it is a new motor assy.
Part 481236158434 and fitting kit 481231028375 this is approx £150 inc postage.Hope this helps.
