LED headlight on the motorized floor nozzle does not turn on, but the brush still spins.

Safety first: Remove the battery pack and detach the floor nozzle.

• 1. Check connections: Inspect the electrical connector between the wand and nozzle. Ensure it is clean and fully seated.
• 2. Inspect LED strip: Look through the transparent lens. If any LEDs appear burnt or dark while others light (if partially working), the strip is failing.
• 3. No simple bulb replacement: On most Grundig cordless vacuums, the LED is integrated into the nozzle PCB or strip and is not user-serviceable.
• 4. Replace nozzle: If the brush works but LEDs never light, replace the motorized floor nozzle assembly if lighting is important for your use.
