Has anyone gone beyond the published diagnostic on the SafetyPro AP2 air purifier diagnostics for shut down code M9039 S4 ? I started a support ticket already but i'm looking to the community as well. 

New machine about 1 week old. The filters are very clean, no pipe clogs, no cyclone clog, no exhaust blockage. Running with a new F1 Ultra in auto and manual. After about 3-6 minutes its stops working and that code appears. I shut it off and restart, then it picks back up in auto mode and keeps working. Full 20 amp circuit running both units.
