Worx Landroid Error E3 — Wire Fault Fix

What Does This Error Mean?

Worx Landroid Error E3 means the boundary wire signal is absent or interrupted — either the base station is not transmitting, or there is a break in the perimeter wire. The mower stops immediately to stay within bounds. Check that the base station is powered on and that the wire is fully intact around the mowing area.

Common Causes

The boundary wire has been cut by a garden tool, spade, or lawnmower
An animal has chewed through or damaged a section of the wire
A wire connector has corroded, loosened, or pulled out at a splice point
The base station has lost power or its signal transmitter has a fault
The wire has been pinched and broken under a heavy stone or garden edging

How to Fix It

Verify the base station is powered on and shows a steady light

Check the base station LED. It should be lit steadily to indicate it is transmitting a boundary signal. A blinking or off LED suggests the station has lost power or has a fault. Confirm the power adapter is fully inserted and the outlet is live.
Inspect the wire connections at the base station terminals

Open the base station and check that both boundary wire ends are firmly secured in the terminal block. Loose, corroded, or frayed connections at the terminals are a frequent cause of E3. Clean the wire ends with sandpaper if corroded, and re-clamp them securely.
Walk the entire boundary wire perimeter looking for cuts or damage

Follow the wire around the full perimeter. Look for dig marks, cut sections, bite marks, or areas where the wire has been disturbed. A severed wire is often found near garden beds, paved edges, or areas that have been recently landscaped.
Locate the break point and repair with a waterproof connector

Once the break is found, use a gel-filled waterproof wire connector to join the two ends. Twist-and-tape repairs fail quickly outdoors due to moisture. Bury the repair slightly and route it so it is not exposed to foot traffic or tools.
Restart the Landroid and confirm E3 has cleared

After repairing the wire, dock the Landroid at the base station and start a mowing session. E3 should clear as soon as the base station detects a complete loop. If E3 persists, there may be a second break — continue inspecting the remaining perimeter sections.

Frequently Asked Questions

Can a Worx Landroid work without a boundary wire?

Standard Worx Landroid models require the boundary wire loop to be intact to operate — without it, the mower cannot define its working area and displays E3. The Worx Landroid Vision models (WR150i, WR200i series) use a camera-based system instead of a wire and are not affected by E3.

Is Error E3 the same as Error E1 on a Worx Landroid?

No. Error E1 on Worx Landroid means the mower has left the boundary area (gone out of the working zone). Error E3 means the boundary wire signal itself is missing or broken, so the mower cannot detect the boundary at all. E1 is a navigation error; E3 is a wire or station hardware problem.
