Hi John, it looks as if the machine has gone into a self test programme.Please try the following.
Open the door turn on the power and press the p button 4 times quickly within 3 seconds.This should bring on the super wash light.Turn the power off and then on again.This should clear the memory.If the memory has a fault,you will have to replace the pcb and they are £116 plus vat and postage.
All the best.
