Not sure which Automower guide you actually need? Start here to find the right fix fast, plus what's genuinely different about the NERA line and common setup mistakes.

Finding the Right Fix Fast, Whatever's Actually Wrong

As the market leader, Automower has more dedicated troubleshooting guides on this site than any other brand — charging, the boundary wire, blades, error codes, the Connect app, and winter storage each have their own full guide already. This article isn't here to repeat any of that. It's here to help you find the right one quickly, and to cover two things none of them touch: what's actually different about the NERA line, and the setup mistakes that get blamed on the mower when they're really an installation issue.


Try This First (2 Minutes)

  • Read the exact message on the display or in the Automower Connect app rather than guessing from a blinking light
  • Note whether you own a standard boundary-wire model (450X, 315X, 305) or a NERA-line model with EPOS — the failure categories genuinely differ
  • Check whether the issue is a hard stop or just a delay, since weather-related messages often resolve on their own
  • Power cycle using the main switch if the display seems unresponsive rather than showing an actual message

Fix 1: Won't Charge or Stuck at the Charging Station (Works Around 20% of the Time)

Dirty contacts, dock alignment, and power supply issues cause most "stuck at the dock" complaints.

How to Fix:

  1. Power off and wipe the charging contact plates on both the mower and station
  2. Confirm the mower docks square, not at an angle
  3. Check the station's power adapter and outlet

Time: 10-15 minutes | Cost: Free | Success Rate: ~20% | Difficulty: Easy

For the full six-fix diagnostic covering contacts, power supply, docking position, and battery recovery after storage, see our dedicated Husqvarna Automower won't-charge guide.

If this doesn't work: Move to Fix 2 if the display specifically mentions a loop or signal fault.


Fix 2: No Loop Signal or Boundary Wire Fault (Works Around 15% of the Time)

How to Fix:

  1. Check the loop signal light directly on the charging station
  2. Walk the visible wire path near the station for cuts or exposed copper
  3. Splice any break with waterproof connectors rated for direct burial

Time: 15-30 minutes | Cost: Free, or $10-20 for splice connectors | Success Rate: ~15% | Difficulty: Moderate

Our dedicated Husqvarna boundary wire fault guide covers the difference between a charging station signal fault and an actual wire break in full — including why NERA/EPOS models still depend on a physical loop at the station.

If this doesn't work: If you own a NERA model, Fix 3 covers what's genuinely different about it.


Fix 3: What's Actually Different About the NERA Line (Works Around 10% of the Time)

This is new ground for this site — NERA models add EPOS (Exact Positioning System) satellite navigation on top of the standard boundary wire, which changes a few things worth knowing before you troubleshoot one like an older model.

How to Fix:

  1. Expect a longer first-start delay after a firmware update or long idle period — the mower needs time to re-establish EPOS positioning, which isn't a fault
  2. Check the app specifically for a GPS/EPOS signal status separate from the standard loop signal indicator, since these are two different alert categories
  3. Note whether poor EPOS signal correlates with dense tree cover or nearby structures rather than assuming a hardware issue
  4. If your NERA model includes the Connect cellular feature, remember it uses a built-in cellular connection, not your home Wi-Fi — router troubleshooting won't help

Time: 5-15 minutes | Cost: Free | Success Rate: ~10% | Difficulty: Easy

Model notes: Applies to the NERA line specifically. Standard 450X, 315X, and 305 models don't have EPOS or a Connect cellular module.

If this doesn't work: Move to Fix 4 if the blades aren't engaging.


Fix 4: Blades Not Spinning or Cutting Poorly (Works Around 15% of the Time)

How to Fix:

  1. Power off and disconnect the battery before checking anywhere near the blades
  2. Clear debris from around the blade disc
  3. Check for a tripped tilt sensor on uneven ground

Time: 10-20 minutes | Cost: Free | Success Rate: ~15% | Difficulty: Easy

Our dedicated Husqvarna blade motor guide covers the full debris, tilt-cutoff, and motor coupling diagnostic.

If this doesn't work: Move to Fix 5 for battery-specific problems.


Fix 5: Battery Not Holding a Charge (Works Around 10% of the Time)

How to Fix:

  1. Check whether the battery drains noticeably faster than it did last season
  2. Confirm it's completing full charge cycles rather than being interrupted
  3. If it's several seasons old, reduced capacity is normal aging rather than a fault

Time: 10 minutes | Cost: Free to check | Success Rate: ~10% | Difficulty: Easy

Our dedicated Husqvarna battery replacement guide covers exactly when to replace it and the model-specific steps for 310/315/315X and 430X/450X.

If this doesn't work: Move to Fix 6 if the Connect app won't connect.


Fix 6: Automower Connect App Won't Connect (Works Around 10% of the Time)

How to Fix:

  1. Confirm you're logged into the correct account
  2. Check the app's cellular signal indicator for the mower, not your phone's own signal
  3. Power cycle the mower to reset its cellular module

Time: 5-15 minutes | Cost: Free | Success Rate: ~10% | Difficulty: Easy

Our dedicated Automower Connect app guide covers account linking, cellular signal, and module reset in full — this is a cellular connection, not a home Wi-Fi issue.

If this doesn't work: Move to Fix 7 for first-time setup problems on a new installation.


Fix 7: First-Time Setup and Installation Mistakes (New Installations, Works Around 10% of the Time)

A meaningful share of "broken" Automower calls on brand-new installs turn out to be setup issues rather than a defective mower.

How to Fix:

  1. Confirm the boundary wire forms a single unbroken loop with no crossed sections before running initial calibration
  2. Double-check the charging station's placement matches Husqvarna's clearance guidance rather than blaming the mower for repeated docking failures during setup
  3. On NERA models, complete a full mapping pass rather than a partial one, and expect the initial EPOS calibration to take longer than a standard model's first run
  4. Review any stay-out zones set during installation — an overly aggressive zone can block access to part of the lawn in a way that looks like a fault later

Time: 20-40 minutes | Cost: Free | Success Rate: ~10% | Difficulty: Easy-Moderate

If this doesn't work: If the display shows a specific alert not covered here, check our Husqvarna Automower error codes guide before continuing to troubleshoot blind.


When DIY Won't Work - Repair vs Replace

Signs it's time for professional service:

  • A NERA-model EPOS signal issue persists in open, unobstructed areas with current firmware
  • A boundary wire fault keeps recurring despite a confirmed intact loop and clean splices
  • The mower shows an error not covered in our error codes guide or your model's manual

Cost comparison: Everything above is free or low-cost to attempt yourself. A dealer diagnostic for a suspected control board or module fault typically runs $60-120.

Warranty check: A confirmed hardware fault is generally covered within the warranty period — setup mistakes and wire damage from landscaping usually aren't.


Prevention Tips

  • Walk the boundary wire each spring before the first mow, especially near the charging station
  • Clean charging contacts every few weeks during mowing season
  • Keep firmware current on every model, especially NERA, since EPOS accuracy improves between releases
  • Review stay-out zones after any landscaping changes
  • Winterize properly each fall — see our dedicated Husqvarna winterizing guide

FAQ

Which Husqvarna guide should I actually read for my problem?

Use this article to identify the category first, then follow the link to the matching dedicated guide for the full step-by-step diagnostic — this one is intentionally a summary and index, not a replacement for those.

What's genuinely different about NERA compared to older Automower models?

NERA adds EPOS satellite positioning on top of the standard boundary wire, and many models include a Connect cellular feature. Both introduce alert categories and startup behavior that older 450X/315X/305 models don't have.

Does NERA still need a boundary wire?

Yes — EPOS reduces how much wire coverage the wider lawn needs, but the charging station still relies on a physical loop for homing and reference.

My Automower seems broken right out of the box. Is that likely, or is it setup?

Setup issues are far more common than a genuine defect on a new unit — check wire loop continuity, station placement, and stay-out zones before assuming a hardware problem.

Does Automower Connect use my home Wi-Fi?

No — Connect-equipped models use a built-in cellular connection, so router and home network troubleshooting doesn't apply to it.

Is a control board or module replacement something I can do myself?

No — that's a job for an authorized Husqvarna dealer, especially while the mower is still under warranty.
