Fluff is principally the result of friction when garments are being worn and to some extent when they are being washed. Tumble drying hardly causes any fluff to form.
Fluff is collected by the fluff filters and the plinth filter and can be removed easily.
Clean the fluff filters as follows:
Open the door.
Pull the upper fluff filter forwards to remove it.
Remove the fluff (see arrows).
Remove the fluff from the surface of all the fluff filters and the perforated laundry deflector.
Turn the yellow rotary control on the lower fluff filter in the direction of the arrow (until you hear it click).
Hold the rotary control and pull the fluff filter forwards to remove it.
Use a vacuum cleaner with a long crevice nozzle attached to remove any visible fluff from the upper air flow openings.
Clean all fluff filters with water:
Wipe the smooth plastic surfaces of the fluff filters with a damp cloth to clean them.
Rinse the filter surfaces through under warm running water.
Shake the fluff filters thoroughly and then dry them carefully.
Push the lower fluff filter in completely and lock it with the yellow rotary control.
Push the upper fluff filter all the way in.
Close the door.
Check and clean the plinth filter as follows:
Press the round, indented area on the heat exchanger access panel to open it.
The access panel will spring open.
Pull the plinth filter out by the handle.
The right-hand guide pin comes out when the plinth filter is removed. The guide pin prevents the access panel from closing without the plinth filter.
Pull the handle out of the plinth filter.
Clean the plinth filter carefully and thoroughly under running water.
To speed up the removal of residue from the surface, run a water jet vertically over the front of the plinth filter.
Squeeze the plinth filter very carefully several times as you rinse it.
Rinse the entire plinth filter thoroughly until all visible residue has been removed.
Continue to carefully squeeze the plinth filter until all of the water has been removed.
To soak up water, place the damp plinth filter between 2 hand towels. On a flat surface, repeatedly press down gently on the plinth filter with a flat hand. This will dry the plinth filter more quickly.
If a drying programme is interrupted with a fault message after the clean plinth filter has been refitted, the plinth filter was too wet when it was refitted. Carefully squeeze the water out of the plinth filter again. Leave the plinth filter to air-dry.
Use a damp cloth to remove any fluff from the handle.
Fit the plinth filter back on the handle. Make sure it is the correct way round.
Look to see if fluff has accumulated on the heat exchanger.
Remove any fluff you can see.
Use a vacuum cleaner to remove fluff and residues.
Push the plinth filter in completely.
This will push in the right-hand guide pin at the same time.
Close the heat exchanger access panel.
