Landroid showing a numbered error code or flashing light? Here's what each alert category means, beyond the wire and charging faults covered elsewhere.
Worx Landroid Error Codes: Every Light & Beep Pattern Explained
Reading a Landroid Alert: Display Code vs. Full Message
Landroid shows a short error code (like E1) alongside a plain-text explanation on the display, and both matter — the code is a quick reference, but the full message tells you which specific fix path to take. This guide indexes the categories and points you to the right dedicated fix rather than repeating full diagnostics that already have their own guide.
Try This First (2 Minutes)
- Read the full display message, not just the short code
- Check the app's alert history if you weren't there when it triggered
- Check the base station's own status light for anything obviously wrong there
- Power cycle the mower using the main switch if the display seems frozen
Wire and Charging Alerts
These already have full dedicated guides rather than a brief summary here:
- "Error E1" / boundary wire fault: see our dedicated Worx boundary wire fault guide for the test-loop method and splice repair
- Mower won't charge at the base: see our dedicated Worx charging guide for contacts, alignment, and power supply diagnostics
- Blades won't engage: see our dedicated Worx blade-not-spinning guide for debris, tilt cutoff, and coupling diagnostics
Fix 1: Tilt or Lift Alert (Works Around 30% of the Time)
Landroid cuts blade power immediately if it detects the chassis tilted or lifted past a safe angle — a safety feature that can trigger on legitimately rough terrain too.
Safety note: Power off the mower and disconnect the battery before inspecting underneath the chassis.
How to Fix:
- Check the lawn area for steep dips or uneven ground that could tip the mower past its rated angle
- Inspect the sensor for mud or grass buildup that could cause a false trigger on level ground
- Clean around the sensor housing with a dry brush
- Restart the mower and run a short test cycle in the affected area
Time: 10-15 minutes | Cost: Free | Success Rate: ~30% | Difficulty: Easy
If this doesn't work: Move to Fix 2 if the alert mentions a collision or obstruction instead.
Fix 2: Collision or Obstruction Alert (Works Around 20% of the Time)
How to Fix:
- Check the bumper for anything physically obstructing it from moving freely
- Clear debris from around the bumper edge
- Manually press the bumper to confirm it springs back on its own
- Restart the mower and watch it navigate around a known obstacle
Time: 5-10 minutes | Cost: Free | Success Rate: ~20% | Difficulty: Easy
If this doesn't work: Move to Fix 3 if you're seeing a rain or weather-related delay message.
Fix 3: Rain Delay Message (Works Around 15% of the Time)
This isn't a fault — Landroid's rain sensor deliberately delays mowing during and after rain, and the message can look alarming if you're not expecting it.
How to Fix:
- Check the app for a rain sensor status rather than assuming a hardware fault
- Confirm the sensor itself isn't dirty, which can cause it to falsely detect ongoing rain
- Clean the sensor if needed and let the delay clear naturally
- Adjust rain sensor sensitivity in the app if it's triggering more often than conditions justify
Time: 5-10 minutes | Cost: Free | Success Rate: ~15% | Difficulty: Easy
If this doesn't work: Move to Fix 4 for a general fault light with no clear message.
Fix 4: General Fault Light With No Clear Message (Works Around 10% of the Time)
How to Fix:
- Power cycle the mower fully using the main switch
- Check the app for any pending firmware update and let it complete if one's in progress
- Confirm the mower isn't simply waiting out a scheduled pause
- Match the exact code shown against your model's printed manual if it doesn't fit any category here
Time: 5-10 minutes | Cost: Free | Success Rate: ~10% | Difficulty: Easy
When DIY Won't Work - Repair vs Replace
Signs it's time for professional service:
- A tilt or collision alert keeps triggering on flat, obstruction-free ground even after cleaning the sensor
- A general fault light persists after a full power cycle and firmware check
- The exact code doesn't match any category here or in your model's manual
Cost comparison: Everything above is free to check yourself. A dealer diagnostic for a suspected sensor or module fault typically runs $50-90.
Warranty check: A confirmed hardware fault in a sensor or module is generally covered if the mower is still within its warranty period.
Prevent Future Alerts
- Clear the mowing area of debris and obstacles before scheduled cycles
- Clean sensors (tilt, collision, rain) on a regular schedule rather than waiting for a false trigger
- Keep firmware updated, since alert logic improves with updates
- Check the app's alert history periodically so patterns show up before a full stoppage
FAQ
Does Landroid use numbered error codes?
Yes, short codes like E1 alongside a full display message — always read the full message rather than relying on the code alone.
Is a rain delay message actually a problem?
No — it's a deliberate feature that pauses mowing during and after rain. It only becomes worth troubleshooting if the sensor itself seems to trigger falsely.
Where do I find the full boundary wire or charging troubleshooting steps?
See our dedicated Worx boundary wire fault guide and charging guide — this article intentionally doesn't repeat that detail.
Is a tilt sensor trigger always a real fault?
Not necessarily — it's a safety feature that can trigger on legitimately steep or uneven ground.
Does Landroid Vision show different alerts than standard models?
The core alert categories (tilt, collision, rain, charging, wire) are shared across the line. Vision may show additional camera-specific status messages not covered here.
Are sensor or module faults covered under warranty?
A confirmed hardware fault is typically covered within the warranty period. Terrain and debris-related false triggers on your property generally aren't.
