    first solenoid, (sv 4) you can fined easily another method of lever lock solenoid, after unplug it's wire socket no error message on the monitor panel after found solenoid loosen it's check nut (13mm wrench) and fully tighten screw. now your machine work normally if not happen lever lock solenoid OK.
