How to Fix / Troubleshooting

Safety first: This involves mains wiring. If you are not qualified, contact a licensed electrician.

  • Check wiring diagram: Refer to the Princess oven's rating plate and wiring diagram for correct single-phase or multi-phase connections.
  • Inspect terminal block: With power off, remove the rear cover and verify that phase bridges are installed as specified and that all screws are tight.
  • Verify supply voltage: Ensure the supply matches the oven's rated voltage.

Correct any wiring errors and restore power. If E16 persists despite correct wiring, the control board's mains detection circuit may be faulty.
