Cordless vacuum does not charge and E4 or a charging error icon appears on the charger base or battery LEDs blink in an error pattern.

Safety: Unplug the charger from the wall before inspecting.

Check power source:

• Verify the wall outlet has power by testing with another device.
• Ensure the Gorenje charger is the original model supplied with the vacuum.

Inspect charging dock and contacts:

• Examine the metal contacts on the dock and on the battery or handle. Clean gently with a dry cloth. Do not use water or abrasive cleaners.
• Ensure contacts are not bent or recessed. If they are misaligned, carefully straighten them with non-metallic tools.

Check cable and adapter:

• Inspect the power cable for cuts, kinks, or exposed wires. Replace the adapter if damaged.
• Plug the adapter firmly into the dock and wall outlet.

Place the vacuum or battery on the dock correctly and watch the LED indicators. If E4 or error blinking persists, the battery pack or internal charging PCB may be defective and should be checked by an authorized Gorenje service center.
