DESCALE LED blinks fast — Infuser at lower position (Test Mode)

What does DESCALE LED blink fast mean?

When the machine is in Load Test Mode, a fast blinking DESCALE LED indicates that the infuser unit has successfully moved to and reached its lowest micro switch position. This is an expected signal confirming the lower limit switch for the infuser is functional during diagnostic testing.

• This is an expected confirmation that the infuser has reached its lower limit switch during a test.
• If the LED does not blink as expected, it could mean the infuser is jammed, the micro switch is faulty, or there's an issue preventing the infuser from moving fully down.

Click steps to track your progress.

1. 1

   Ensure the machine is correctly in 'LOAD TEST MODE' as described in section 5.1 of the manual.

2. 2

   Visually inspect the infuser area for any obstructions, such as coffee grounds, that might prevent it from moving to its lowest position.

3. 3

   Repeat the test mode sequence to observe if the DESCALE LED blinks fast when the infuser moves down.

4. 4

   If the LED still does not blink as expected, consider cleaning the infuser unit according to the main user manual, then re-test.
