Possible Causes
Control PCB logic fault, corrupted power‑on self test, stuck brew button switch, low line voltage or unstable power supply
How to Fix / Troubleshooting
Safety first: Unplug the Senseo coffee maker before opening any covers. Never work on the unit while it is connected to mains power.
Step-by-step checks:
- Power reset: Unplug the machine for at least 10 minutes to allow the control PCB to fully discharge. Plug back in and try again.
- Check outlet and power strip: Test the outlet with another appliance. Avoid using long extension cords or overloaded power strips.
- Inspect brew button: With the unit unplugged, press the 1‑cup and 2‑cup buttons repeatedly to free any stuck switch. Plug back in and test.
- Descale if prompted: Some models flash all LEDs when a severe scale error is detected. Run a full descaling cycle with citric‑acid or Senseo‑approved descaler following the user manual.
- If error persists: The control PCB or internal sensor network may be faulty. Do not bypass safety circuits. Contact a qualified service technician for board diagnosis and replacement.
