Mine was showing no power indications at all, no light, no motor, etc. Checked the fuse by cutting back the heat shrink tube and it was good so I used my multi-tester and traced the power up to the handle where the switch is. Removed the screws, 3 outside and one inside, split the handle and there are 3 wires coming from the hose to the
wand. One wire there had slipped from it's clip and was disconnected. I pushed it back in now it works just fine.
