Cordless vacuum shows E8 and suction is very weak even with clean bin

Safety first: Turn OFF the vacuum and remove the battery or ensure it is switched off before disassembly.

• Step 1 – Re-seat dust container: Remove and reinstall the dust bin, ensuring it clicks firmly into place and that all rubber seals are seated correctly.
• Step 2 – Clean or replace HEPA filter: Remove the exhaust/HEPA filter. Tap gently to remove dust. If heavily grey or damaged, replace with a genuine Philips HEPA filter.
• Step 3 – Inspect internal ducts: With the bin removed, look into the inlet and outlet ducts for compacted dust or foreign objects. Use a soft brush to clear.
• Step 4 – Check seals and gaskets: Inspect the rubber seals around the cyclone, bin, and filter frame. Replace any that are torn or deformed.
• Step 5 – Test suction: Reassemble and test on low and high power. If E8 persists and suction remains weak, the airflow sensor or main PCB may be defective and should be replaced by a technician.
