Possible Causes

Failed low‑voltage power supply on main PCB, Shorted component on control board, Loose mains connection causing brownouts

How to Fix / Troubleshooting

Safety: Unplug the unit before removing any covers. Mains voltage is present on the control board.

Steps:

  • Check mains plug and socket: Ensure the plug is fully inserted and the socket is not loose or burnt.
  • Inspect internal wiring: Access the main PCB and check the mains input terminals for tightness and signs of overheating.
  • Visual board check: Look for bulged capacitors or burnt components in the low‑voltage section.
  • Test output: If you are trained and equipped, measure the DC output voltages from the board and compare to Neff specs.

Resolution: If the low‑voltage supply is unstable or missing, replace the main control module. Board‑level repair is not recommended for untrained users.
