I have two Bosch dishwashers with the same fault. The Dishwasher will not drain. It is not displaying a fault code. It will not drain when the program is cancelled and wont drain when the anti flood device is activated, it does display E15 when this is done. There is nothing stuck in the pump and it has had a new pump fitted. The pump does work for a few seconds but then stops. Water does come out of the drain hose so that’s not blocked. Has anyone had the same fault or have I missed something. I suspect the control panel. Could anyone confirm this please.
