Robot vacuum stops and pivots in place; E3 error or voice message about right wheel problem.

Safety first: Switch the robot OFF and remove it from the dock.

Steps to try:

• 1. Check right wheel rotation: Turn the robot over and spin the right wheel by hand. It should move freely. Any grinding or sticking indicates a jam.
• 2. Remove hair and fibers: Carefully cut and pull out hair or threads wrapped around the wheel axle and hub. Inspect deep inside the wheel cavity.
• 3. Clean the wheel housing: Use a small brush to remove dust and grit from the wheel housing and suspension area.
• 4. Run a test: Power the robot ON, start a cleaning cycle, and observe if the right wheel now spins. Stop the robot after a few seconds.
• 5. Inspect internal connection: If the wheel still does not move, remove the bottom cover and verify the right wheel module connector is firmly attached to the main board and that no wires are broken.
• 6. Replace right wheel module: Persistent E3 errors usually require replacing the right drive wheel assembly with a Gorenje‑specified part.
