I had the same problem last week, after cleaning the source I had a HED Fault. I also saw a high baseline while tuning. According to Agilent probably a speck of dust some where on or near the HED or electron multiplier. Agilent has a PDF explaining how to clean those. After cleaning the HED and electron multiplier no more HED fault.
