Robot mower wheel motor fault
Use the exact error message and model name. The same symptom can come from the installation, dirt, power, terrain, software or a component, so do not order parts until the basic checks are complete.
Start here
Switch the mower off safely. Record the complete message, when the fault happens and the charging-station light. Then check visible obstructions, power, contacts and any recent installation or garden changes.
Check in this order
- Confirm the brand, exact model and full error text in the mower display or app.
- Check charging-station power, accessible charging contacts and visible cable connections.
- Clean only accessible wheels, contacts and cutting components as allowed by the model manual.
- Restart with the manufacturer’s normal procedure and observe whether the fault returns in the same location.
- Use authorised service if diagnosis requires opening a sealed battery, power supply or electronic assembly.
Why the cause must be narrowed down
An error code normally identifies the system that stopped operation, but not necessarily the failed part. The exact model, location, station status and event before the stop help separate installation and environmental faults from hardware faults.
New Zealand guidance uses lawn, boundary-wire and metric terminology. Wet conditions, slopes and soft ground can imitate drive, docking and boundary faults, so note weather and terrain before replacing parts.
Safety
Never open a sealed lithium battery or bypass a safety system. Isolate station power before handling exposed station wiring. Stop if you find swelling, burning smell, water ingress, damaged insulation or exposed conductors.
Should I buy a replacement part immediately?
No. Complete safe external checks and confirm the model and exact message first. Buy a part only after the likely cause has been narrowed down.
