Small electrical parts fail in the most frustrating ways: intermittently, under specific conditions, and always at the worst possible time. Diagnosing them takes patience and a meter. Replacing them is the easy part; finding out which one is the problem is the hard part.
This is the genuine Nilfisk Advance OEM VALVE-SOLENOID-120V, part number 56265560, brand new in the box. Once you've narrowed it down, get the genuine replacement — same contact ratings, same certifications, same interchangeable geometry. Aftermarket electrical parts are how "fixed" turns into "broken again in three months."
