What Ground too fine. Adjust grind level 1 level while in operation means

On the Bertazzoni CM242WTXT built-in coffee machine, this message means the grinding is too fine. Coffee is delivered too slowly or not at all. It can also mean an air bubble in the circuit when the water softener filter is fitted. The remedy is to adjust the grind level by one level, and only while the grinder is operating. Owners see a weak trickle or an empty cup.

Common causes of Ground too fine. Adjust grind level 1 level while in operation

  • A grind level set too fine for the beans
  • An air bubble in the water circuit with the softener filter fitted
  • Oily beans that pack tightly
✓ One safe check you can try

1. Start a coffee and, while the grinder is running, turn the grind setting one level coarser. 2. Make another cup and see whether the flow improves. 3. If a water filter is fitted, run a rinse so air can leave the circuit. 4. If coffee still flows slowly or not at all, call us.

! Why to stop there
  • Changing the grind outside a grinding cycle can damage the grinder.
  • A persistent blockage or flow problem needs the brew unit inspected.
  • We quote in writing first, and our repairs carry a 30-day workmanship warranty.
Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

Ground too fine. Adjust grind level 1 level while in operationGround too fine. Adjust grind level 1 level while in operation questions
Why do I only change the grind while it is operating?

The setting is meant to be adjusted while the grinder is running. Moving it at rest can jam the mechanism, so move it just one level at a time as it grinds.

What does the water filter have to do with this message?

With the softener filter fitted, an air bubble in the circuit can produce the same slow or missing flow. Running water through the circuit usually pushes the air out.

How do I know if the grind is the problem?

If coffee comes out thin and slow, with dark, tightly packed grounds, the grind is too fine. Coarser by one level often corrects it. If not, we examine the brewing path.
