Siemens Code 9000 461 581 (8909). I can find no model number in the machine.
The machine mostly empties but leaves a small amount of water in the well, not higher than the filter. This is sufficient to prevent it restarting and to make it give an E24 message. The pump is rotating and there are not obvious obstacles. If the well is emptied manually the machine starts fine and goes through a complete cycle.
So…. I infer there is not a pump problem or an outlet hose problem. The pump is stopping prematurely at the end of the cycle. Could this be a sensor problem?
