You have two filters to wash: the Pre-filter on top and the Post-filter on the back. It's straightforward if you take it step by step.
FIX: First, remove them.
- For the Pre-filter: Lift it straight out of the top of the cyclone.
- For the Post-filter: Twist it anti-clockwise and pull it away from the back of the machine.
DRYING IS CRITICAL: Place both filters with their open ends facing up. Let them dry for at least 24 hours in a warm, well-ventilated spot. Do not use a tumble-dryer or place near heat. They must be completely dry before you put them back.
HEADS UP: Your machine could be damaged if used with a damp filter. When refitting the Pre-filter, align the arrow on it with the bin release button before pushing down.
