Coffee Machine Not Self Cleaning

A self-cleaning cycle that will not start is usually caused by a clogged cleaning path, an unseated brew unit, or a sensor that still detects the drip tray as full.

⚡ TL;DR — Quick Answer

Empty and reseat the drip tray, check the brew group is locked in, and run the cleaning cycle again with fresh water.

Understanding Not Self Cleaning

Self-cleaning programs are blocked by safety checks: the machine will not run the cycle if the drip tray is full, the brew group is open, or water is low. Scale in the cleaning path can also stall the pump. Resolving the blocking condition usually lets the cycle finish.

Universal Troubleshooting Steps

These steps work across all major brands:

  1. Empty and reinsert the drip tray, making sure it clicks into place.
  2. Remove and reinsert the brew group; check it is locked correctly.
  3. Refill the water tank above the minimum line.
  4. Run the cleaning cycle again; if it stalls, descale first to clear the cleaning path.
