Hey guys, I have a 22kw gaurdian and it has been working fine in Auto mode, does its test once a week long story short haven't had any problems. The girl friend was pressure washing around the unit today and it fired up and started running while the house still has utility power. Shut machine down manually and put it back in auto and machine cranked up again and started running.

It sounds like maybe she got water into the control wiring somewhere and shorted out a fuse which blew and is telling the gen you have no power now.

Check the N1 and N2 fuses in the transfer switch.
