It's not getting power. Check the basics first.
- Verify the power cord is firmly plugged into both the purifier and a live wall outlet.
- Test the outlet with another device, like a lamp, to confirm it's working.
- Inspect the power cord for any visible damage, cuts, or fraying.
IF THAT DIDN'T WORK: The internal fuse or power switch may have failed. Unplug the unit. There's no user-serviceable fuse. This requires professional repair or replacement of the unit.
HEADS UP: Never operate an appliance with a damaged power cord. It's a fire and shock hazard.
