Bendix BIW105W won't run any programme: "end" light flashes 4 times?

Our Bendix BIW105W washing machine got near the end of a cycle, but didn't appear to drain or spin. I emptied the remaining water out through the drainage hose and cleared the pump impeller, but it now won't go. No matter which programme I turn the switch to, the normal lights come on, but when I press the start button the lights turn off and the "end" button flashes four times (then pauses, then flashes 4 times etc ad infinitum). Can anyone tell me what this mean, and more importantly, how to fix it?
