DISPATCHAlways disconnect appliance from 230V/400V mains before opening panels. Use CAT III multimeter for circuit testing.
Frequently Asked Questions: Castor F106
FAQ TREEWhat does error code F106 mean on a Castor appliance?
Castor error code F106 indicates: Castor COB Series / Forno Multifunzione Oven: Heating safety relay welded F106; main PCB detects continuity through heating element relay contacts when deactivated..
What is the root cause of Castor error code F106?
The primary root cause for Castor code F106 is: On Castor (Castor COB Series / Forno Multifunzione Oven) models: Electrical arcing welded the 16A relay contacts on the power PCB, or transient voltage spike degraded the relay coil switching driver..
How do I fix or resolve Castor error code F106?
To resolve error code F106: Disconnect oven mains immediately. Inspect relay contacts on power PCB with ohmmeter (must read ∞ Ω open circuit when unpowered). Replace PCB or relay. Hold Start and Reset keys for 5 seconds until the display clears the alarm code and restores standby status.
Is it safe to clear Castor error code F106 by resetting power?
Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Castor code F106 persists, the physical component causing On Castor (Castor COB Series / Forno Multifunzione Oven) models: Electrical arcing welded the 16A relay contacts on the power PCB, or transient voltage spike degraded the relay coil switching driver. must be inspected or replaced.
How do I test electrical resistance for Castor code F106 using a multimeter?
Set a digital multimeter to ohms (Ω). Disconnect power and test Immersion / Air Heating Element & Klixon Thermostat across Between element terminals (unwired). Insulation to earth casing: >20MΩ (OL). Expected nominal reading is 25Ω–28Ω (230V / 2000W) / <0.5Ω (Safety Klixon closed). Tolerance: Formula R = V²/P (±5%). Any earth leakage reading below 2MΩ will trip the domestic 30mA RCD breaker..
What safety protocol must be followed before servicing Castor code F106?
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.
