My Siemens dishwasher shows an E11 code in the display.

Our dishwashers are fitted with a self-diagnosis system, which in the rare case of a fault will help to report what the problem is. If the E11 or F11 error code appear on the appliance display we recommend that you do not try to resolve the issue on your own at home due to health and safety reasons. Please close the water tap and switch off the appliance.
