Bosch Coffee Machine Empty Trays: Message Stays After Emptying

What Empty Trays means

The display asks for the trays to be emptied, and it keeps asking after you have done it. Two electrical contacts sit above the drip tray. When liquid rises and touches both, the resistance between them drops and the machine reads the tray as full. So a message that persists usually means water or damp grounds are still bridging those contacts, not that the trays are full.

Common causes of Empty Trays

Drip tray or dregs drawer genuinely full
Wet coffee residue bridging the contacts above the tray
Trays refitted before the contact area had dried

✓ One safe check you can try

1. Pull out the drip tray and the dregs drawer and empty both. 2. Wipe the contact area carefully with a soft cloth, getting rid of any damp grounds or water film. 3. Dry everything, then slide the trays back in until they sit flush. 4. Run one drink. If the message stays, call us.

! Why to stop there

Pushing wet cloths or tools around the contacts can bend them and cause the same message permanently.
Running the machine with a full tray can overflow onto the counter and the electronics below.
Scrubbing with harsh cleaners can corrode the contacts and make false readings more likely.

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.

Empty TraysEmpty Trays questions

Why does the message return right after I empty the trays?

Damp grounds or a thin film of water can connect the two contacts, so the machine still reads the tray as full. Drying the contact area thoroughly usually resolves it.

How often should the trays be emptied?

Empty them whenever the machine asks, and wipe the dregs drawer area regularly. Letting wet grounds sit invites buildup around the contacts, which is the main source of nuisance messages.

Does a stubborn message mean the machine is damaged?

Not necessarily. Most cases are residue. If cleaning and drying do not help, the contacts or their wiring may need attention, and we quote the repair in writing before starting.
