Philips / Saeco Error 04: brew group not locked

Error 04 means: Brew group is not correctly placed.

How to fix Error 04

1. Remove the brew group. Check the lever on the side is in the rest position and the two reference marks line up (yellow arrow to arrow on most models).
2. If it is not, press the top of the group until it clicks down; do not force the lever.
3. Refit along the guides until it clicks, close the door.
4. Switch on; the machine will index the group itself.

When to stop and call a repairer

Never force the group in; a cracked group is a new group.
