We have moved into a new house with a F and P dishwasher model no. DW60CSX1. There was no manual when we moved in. The dishwasher doesn't want to work.. when you put it on, about 10 seconds later it beeps and flashing lights appear on the 'normal, fast and rinse' buttons and beeps beeping and flashing until you switch it off. Can you please tell me what this error is and how I can fix it. I drained all the water out by hand and can not see or feel any blockages under the drainage filters.
