- Collection bin full
- HEPA or cartridge filter clogged or damaged
- Suction hose blocked or leaking; build-up in ducting
- Vacuum motor failure
- Worn seals at the dosing or turntable area
- Powder unusually fine for the extraction setting
- Excess powder generation from machine adjustment
How to fix it
