Frequently Asked Questions

How often should I clean the charging contacts on my Husqvarna Automower?
Clean the charging contacts monthly during mowing season or whenever you notice poor charging performance. In dusty or debris-heavy environments, you may need to clean them more frequently.
Can I use water to clean the contact pins?
No, never use water or liquid cleaners on electrical contacts. Use only dry cleaning methods like cloths, brushes, or fine sandpaper to avoid damaging the electrical components.
What causes debris to build up on Automower charging contacts?
Grass clippings, dirt, and moisture can accumulate on contacts over time. The mower's cutting action creates debris that can stick to the metal contacts, especially in humid conditions or when mowing wet grass.
Will Error Code 16 damage my Husqvarna Automower?
Error Code 16 itself won't damage your mower, but prolonged poor charging connections can lead to battery issues. Clean the contacts promptly to ensure proper charging and extend battery life.
How do I know if my charging station contacts need replacement?
Replace charging station contacts if they're severely corroded, bent beyond repair, or if springs are broken and won't maintain proper pressure. Clean contacts should be bright and make firm contact with the mower.
