Problem Solution
Perhaps the tap water pressure is higher than
specified.
You may need to wind some Teflon tape around the
screw thread of the adapter.
The water
flow is weak at
the unfiltered
setting.
Perhaps the stainless steel screen under the rubber
washer inside the water purifier housing is clogged.
Clean it with a soft brush and rinse it.
The water
flow is weak at
the filtered
setting.
Perhaps the filter cartridge is clogged. Replace the
filter cartridge.
Perhaps the tap water pressure is lower than
specified.
Perhaps you are using a filter cartridge whose
lifetime has expired. Replace the filter cartridge.
Air may be trapped inside the filter cartridge. This
may happen when you install a new filter cartridge.
To avoid this, slightly open the tap for 30 seconds
immediately after you install/replace the filter
cartridge. The slow stream of water removes any air
trapped in the filter.
The display
is empty after I
have replaced
the battery.
Perhaps the tap water pressure is lower than
specified.
Perhaps the poles of the battery point in the wrong
direction. Insert the battery in the correct way (see
section ‘Inserting the battery’ in chapter ‘Preparing
