Cordless vacuum stops and shows E5 when using turbo or maximum power mode

Safety first: Use only original Kärcher chargers and batteries. Do not open the battery pack.

• Fully charge the battery: Place the battery on the original Kärcher charger until the indicator shows full charge. Then test the vacuum again.
• Test on lower power: Run the vacuum on normal/eco mode. If it works in eco but triggers E5 in turbo, the battery may not be able to supply peak current.
• Try another battery: If you have a second compatible Kärcher battery, test with it. If E5 disappears, replace the original battery pack.
• Check battery contacts: Inspect and clean the contacts on both the battery and vacuum with a dry cloth. Poor contact can cause voltage drops under load.
• Persistent E5 with multiple batteries: The main control PCB’s voltage sensing or power stage may be faulty. Professional service is recommended.
