It's a simple chip problem, the internal chip gets confused and as with all dishwashers over 6 months old, the rattle and it causes the chip to malfunction. a new one should cost you around £25 but getting it fitted would cost more. your best bet is to see if your warrantys still of any use, comet.co.uk were helpful to me with my bosch dishwasher about 6 months ago. good luck
