Frequently Asked Questions

What causes Husqvarna error code E10?
Error E10 is caused by dirty, corroded, or oxidized charging contacts that prevent proper electrical connection between the mower and charging station. Grass clippings, moisture, and normal wear can cause this buildup over time.
How often should I clean my Husqvarna mower charging contacts?
Clean the charging contacts monthly during mowing season or whenever you notice slower charging. In dusty or wet conditions, more frequent cleaning may be needed. Regular maintenance prevents error E10 from occurring.
Can I use WD-40 or other lubricants on charging contacts?
No, never use WD-40, oils, or chemical cleaners on charging contacts. These can create insulation that prevents electrical connection. Only use dry cleaning methods or fine sandpaper for stubborn corrosion.
Will error E10 damage my Husqvarna mower?
Error E10 itself won't damage your mower, but leaving it unresolved can lead to incomplete charging and potential battery issues over time. Address the error promptly to maintain optimal mower performance and battery life.
Why does error E10 keep coming back on my Husqvarna mower?
Recurring E10 errors usually indicate worn charging contacts, poor charging station placement in wet/dirty areas, or underlying electrical issues. Consider relocating the charging station to a cleaner, drier area or having contacts professionally inspected.
