Bauknecht second-hand hand, user for 3 times, with good results. Owner came while away to properly install it, now the machine is locked, with some water inside. Tried to run a program, but stops at a certain point, with the LED Pump blinking Red. I tried to flush the water using the button, but It shows an error code, E5, I suppose. In both cases, a continuous sound can be heard. I do not know how to reset or what could be done. TIA
