							Cleaning the filters in the wash
cabinet
The filters in the base of the wash
cabinet are designed to prevent coarse
soiling getting into the circulation
system.
A build-up of coarse soiling can cause
the filters to clog up. They should,
therefore, be checked daily and
cleaned if necessary.
The machine must not be used
without all the filters in place.
Watch out for glass splinters
which could cause injury.Cleaning the fine filter
Remove the filter and clean it.
Cleaning the flat filter
