Hi Jimmy, these are quite complicated machines and were updated along its life.E2 is a flooding fault but on this model it is usually the air break and the feeder tubes are blocked.It is really an engineer job as the repair is quite involved depending on its age.The air break comes as a kit and other parts have to be exchanged.For your info, the air break is £85 plus vat and postage and the labour is £70 plus vat but still cheaper than a new dishwasher. All the best.
