Safety Boundary
Stop before opening powered housings, bypassing thermal protection, or working around exposed heating elements.
Start Here
- Unplug before cleaning needles, tanks, or removable parts.
- Check reservoir seating and water level.
- Run manufacturer-approved descaling when flow is weak.
- Record whether the error appears before brew, during pump, or after heat-up.
Decision Path
- Weak or no flow: Descale, reservoir seating, needle cleaning, and pump priming are the first safe branches.
Next: Review flow and descale codes. - Won't heat: Heating faults have less DIY room than cleaning or reservoir problems.
Next: Use heating and power code pages. - Pod or sensor issue: Check pod seating, lid latch, and debris before assuming a board fault.
Next: Compare pod, latch, and sensor codes.
Stop and Call for Service
- Burning smell
