Cleaning intervals
The filter system 1b is designed to
minimize maintenance while
providing premium cleaning

some maintenance to sustain
premium cleaning performance.

■
on the filter system or objects
trapped in the Large Object Trap.
A drop in cleaning performance
■
or a gritty film forms on the
dishware.

runs the dishwasher every other day,
your filter should be cleaned:
