Robot mower displays E5 and stops, often when wheels slip or get stuck.

Safety first: Turn OFF the mower and keep it stable before lifting. Do not work near the blades unless power is off.

Steps to check:

• Inspect wheels: Check both drive wheels for sticks, stones, or wire wrapped around the axles. Remove any foreign objects.
• Clean wheel treads: Remove built‑up grass and mud from the Worx Landroid wheel treads and hubs to restore traction.
• Spin test: With the mower lifted, rotate each wheel by hand. They should turn smoothly with some gearbox resistance. Grinding or tight spots indicate gearbox or motor issues.
• Check terrain: Reduce steep slopes, deep ruts, or soft soil where the mower frequently gets stuck. Add boundary wire to exclude problematic areas.
• Reset: Allow the mower to cool for 10–15 minutes, then restart and test.

When to call a technician: Persistent E5 on the same wheel suggests a failing wheel motor or gearbox that should be replaced as a complete drive wheel motor unit.
