After realising the jetwash system was inop I removed and cleaned out both pumps and all pipework associated with these. I accomplished this by tipping the m/c on its back to gain access the pumps (dont know if this is correct method).after re-assembly programme will not start. the start button emits the normal bleep but the water inlet solenoid does not attempt to open. any help would be most appreciated. carried out further checks and it seems I have an error E51 but dont know what this relates to.
