Automower charging keeps cutting out — contacts, power supply, or station?
A healthy Automower charge runs in one unbroken block — roughly 1–3% per minute depending on
model — until full. Two patterns mean trouble:
- Charging ↔ ready flapping every few seconds in the app while docked.
- Charging that dramatically slows or stalls partway through.
Work through it in this order
- Contacts (free): clean the mower's charging strips and the station's contact plates
with fine sandpaper or a brass brush. Check the mower seats firmly and the station sits level.
If charging is fine when everything is cool but degrades 10–20 minutes in, contacts are
probably not your problem — read on.
- Power supply under load (~€60–90): an ageing supply can read normal voltage unloaded
yet collapse rhythmically under charging load (“hiccup mode”). Telltales: the station LED
cycling green→red→off→green, and loop-signal errors (E02) appearing only while docked. Measure
at the station end of the cable during a flap — if the voltage sags in sync, replace the
supply. If it sits in direct sun, heat accelerates all of this.
- Station board: only if a known-good power supply doesn't cure it.
One subtle consequence of interrupted charging: the mower keeps trying to resume its
schedule with a half-full battery, so sessions get shorter and the lawn develops uncut patches
before you ever see an error.
MowerWatch spots this automatically. It watches your Automower®'s own API data,
reconstructs every stop with its cause, and tells you which part to check — before the
dealer visit.
