Bertazzoni Coffee Machines DRAWER FULL Error: Used grounds bin is full
What Does “Drawer Full” Mean on a Bertazzoni CM24 Coffee Machine? After each brew cycle the Bertazzoni CM24 ejects a compact spent coffee puck into an internal used grounds bin. The machine counts each puck deposited and, when it reaches the programmed Drawer Full threshold — 20 pucks by default, adjustable between 1 and 35 […]
Quick Assessment
Answer to continue safely
Is it safe to keep using?
Yes. Drawer Full is a normal routine maintenance reminder, not a hardware fault. Empty the grounds bin, re-seat it correctly, and the machine returns to normal operation immediately.
Can I reset the code?
Yes. Emptying and correctly re-inserting the grounds bin automatically clears the Drawer Full message and resets the internal cycle counter.
When to stop immediately?
Stop if you notice: Drawer Full appears immediately after emptying and re-inserting the bin, Bin cannot be fully inserted — something is physically blocking the slot.
Symptoms You May Notice
Machine was making drinks normally and suddenly stops accepting any brew commands with no prior warning
The CM24 counts each brew cycle internally. When the count reaches the programmed threshold, it locks out all drink functions at the next power-on or at the next brew attempt, depending on the timing of the count.
Display reads "Drawer Full" and all brew, espresso, and hot-water buttons are unresponsive
The lockout is intentional — it prevents the spent grounds bin from overflowing into the machine interior, which would require a much more involved clean-up and could jam the grounds ejector mechanism.
Possible Causes
Used coffee grounds bin reached its programmed capacity
The CM24 deposits a spent puck into the internal grounds bin after each brew. The warning threshold (default 20 pucks) triggers Drawer Full to prevent overflow into the internal cavity.
DIY PossibleGrounds bin sensor or cycle-count error
If the bin was emptied without being re-inserted correctly before the counter reset, or if the bin-present sensor is dirty, the machine may display Drawer Full prematurely with an empty bin.
DIY PossibleSafe Checks You Can Do

Empty and correctly re-seat the used grounds bin
Remove the drip tray, open the front panel, and pull out the used grounds bin. Empty it, rinse with water, dry, and push it fully back into position until it clicks firmly.
An incompletely seated bin triggers "Machine Ready - Drawer Out" instead of clearing the Drawer Full message. Push the bin all the way in until you feel the positive click of the bin-detection latch.
When to Call a Professional
Contact a qualified technician if:
- Grounds bin detection sensor reads negative even with the bin fully inserted
- Bin cycle counter in the service menu is not incrementing or resetting correctly
- Bin slot is mechanically deformed and prevents full insertion
