Similar problem, mine will not drain on any program, E03 appears.
Filter and hoses clear, pump not rotating. Got voltage going to pump looks like pump motor open circuit.
My washer has developed this fault tonight, 12 days over its 12 month warranty. Will be interesting talking to their service department in the morning.
Not been able to get a part number for the pump but reckon somewhere between £20-£30.
