Bompani F18

Bompani error code F18 indicates: Bompani Serie Divina / Linea Built-in Multifunction Pyrolytic & Convection Oven: Operational diagnostic fault code F18 signaled by internal electronics. Supply operating voltage too low under load (<185 VAC RMS recorded on main terminal block).

The primary root cause for Bompani code F18 is: On Bompani kitchen suites engineered with PT1000 cavity RTD sensor (1080 Ω at 20°C), bi-directional tangential cooling fan, motorized pyrolytic door lock, and 2300W convection circular element: Loose neutral wire at terminal block, undersized supply cabling, or regional utility brownout condition Multimeter diagnostic parameter: mains voltage must remain between 207 VAC and 253 VAC RMS (230V ±10%) with heating elements energized..

To resolve error code F18: Safely de-energize the appliance at the electrical distribution board. Unplug wiring connector from the affected component and verify with a digital multimeter: measure AC voltage between Line and Neutral directly at the rear terminal block while activating bake mode. Inspect spade lugs for signs of heat discoloration. Replace defective component, restore electrical supply, and perform system reset: Turn oven selector knob to OFF position. Press and hold Temp and Timer buttons simultaneously for 5 seconds until 'rSt' flashes, then press Start to confirm memory wipe.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Bompani code F18 persists, the physical component causing On Bompani kitchen suites engineered with PT1000 cavity RTD sensor (1080 Ω at 20°C), bi-directional tangential cooling fan, motorized pyrolytic door lock, and 2300W convection circular element: Loose neutral wire at terminal block, undersized supply cabling, or regional utility brownout condition Multimeter diagnostic parameter: mains voltage must remain between 207 VAC and 253 VAC RMS (230V ±10%) with heating elements energized. must be inspected or replaced.

Set a digital multimeter to ohms (Ω). Disconnect power and test NTC Temperature Sensor Probe (Thermistor) across Across sensor pins 1-2 (unplugged harness). Expected nominal reading is 4.8kΩ–12kΩ (at 20°C–25°C). Tolerance: Negative temperature coefficient: resistance drops smoothly when warmed with fingers. OL = open circuit..

Standard electrical safety protocol: 1. Disconnect 230V mains power before opening panels. 2. Verify zero voltage at test points. 3. Allow hot water or heating elements to cool below 30°C before handling.
