Philips WP3820 - Manual (Page 20)

Problem Solution
Perhaps the battery compartment cover is not
properly fitted. Reattach the battery compartment
cover in the correct way (see section ‘Inserting the
battery’ in chapter ‘Preparing for use’).
Perhaps the water purifier is set to the unfiltered
spray setting or the unfiltered stream setting. In
these cases, the display is off. The display only works
when the water purifier is set to the filtered spray
setting.
The
display suddenly
goes empty.
Perhaps the battery is low. Replace the battery.
Perhaps the filter cartridge is clogged and water flow
is extremely slow. Replace the filter cartridge.
The appliance
makes a clicking
sound when I
use it at the
filtered spray
setting.
The clicking sound comes from the built-in flow
meter and is normal.
