Note: The most common cause for a loss in
exhaust suction is a dirty chaff filter bag. The bag
will plug much faster with darker roasts which
produces oily residue captured by the bag.
The filter bags are machine washable. Check filter
bags often and replace when dirty.
Clean filter bags reduce exhaust temperature and
keep your machine running smoothly.
