Wassermann WAPO-Ex, Service Manual, Page: 16 / 24

To change the filter and clean the level sensor (white ring), first remove
the cap containers. The perforated plate can then be taken out and you
can remove the flat filter. When inserting a new one, make sure that the
white side is face down and that the filter fits under the raised edge of
the base plate. The base plate is easily removed, giving ready access to
the level sensor and the heater coil. Re-insert the base plate with its
raised edges facing upwards.
