Schaerer Coffee Machine Message: Grinder Left/Right No Beans
Grinder left/right no beans on a Schaerer Coffee Art Plus Touch means the left or right bean hopper is empty or a bean has become stuck. Refill the hopper (maximum 1000 g) and confirm on the display, then check the bean slides. Beverage output is blocked until then.
Low: an operator refill prompt; drinks from that side stop until it is cleared.

What does Schaerer Grinder left/right no beans mean?
The Coffee Art Plus Touch has two bean hoppers, one for each grinder. The machine senses when the grinder it needs has no beans to grind, and it stops that drink and shows Grinder left/right no beans. The wording tells you which side ran out. Two things are behind the message in the manual: the hopper is empty, or a bean has become stuck so that none is reaching the grinder, even though the hopper is not empty. The first is a refill, up to 1000 grams. The second shows up when a hopper looks full but the message comes back, and the manual's response is to check the bean slides and, if they are jammed, to stir the beans with the stem of the cleaning brush and confirm. Oily beans and large chunks are the usual reasons for a bean sticking.

Safe checks before calling for service
- Look at the hopper named in the message and refill it with beans, up to 1000 g.
- Confirm on the display.
- If the hopper is full, check the bean slides for a jam.
- If jammed, stir the beans with the stem of the cleaning brush, then confirm.
- If the message returns, note which side and which beans you use, and call for service.
How a technician diagnoses Grinder left/right no beans
- Check which hopper is named and whether it holds beans.
- Inspect the bean slide and grinder opening for bridging or a stuck bean.
- Remove old, oily beans and clean the hopper.
- Check that the hopper's bean sensing reads correctly with beans present.
- Check the grinder motor turns freely.
- Test a drink from each side.
- Reaching the grinder mechanism means removing the hopper and working next to blades.
- A sensing or motor problem is tested with the machine's covers off and power on.
- Bean choice and grinder settings affect other drinks and are set by the technician.
