7.2 Replacing the water filter (MAJ-824)
Replace the water filter at least once a month to prevent contamination of the
rinse water. The water filter should also be replaced whenever an error code
indicating water supply insufficiency [E01] is displayed. The water filter should be
replaced by following the flow shown below.
• Filter life varies depending on a number of factors including
incoming water quality and use volume.
• Using at least a prefilter (0.45 micron or less) can extend the
life of the water filter. If the prefilter is properly installed, the
water filter and the prefilter should be replaced at least once
every 6 months. For information on the Water Pre-filtration
system, contact Olympus.
