Grinder and dosing motor fault codes
19 codes across 4 brands, from Breville / Sage, Jura, Philips / Saeco, De'Longhi.

What these parts do
The grinder motor drives the burrs, and on some machines a separate motor doses or tamps the grounds. The board watches current or an encoder to confirm each one actually turned.
How they fail
The motor was told to run and did not turn, or turned too slowly. A foreign object between the burrs (a stone from the bean bag is the classic one), clumped roast debris or a seized motor all give the same code.
Safe checks first
- Unplug the machine, empty the bean hopper and look at the beans left at the bottom for stones or clumps.
- Vacuum the hopper outlet and grinder throat with a plastic nozzle. Never push metal into the burrs.
- Empty the grounds container and drip tray, refit both, and restart so the machine re-homes.
- If the grinder hums without turning once everything is clear, the motor is seized.
Appliances carry mains voltage. Unplug before opening anything, and stop where a code's own page tells you to.
