Possible Causes
Incorrect mains connection (single-phase vs. two/three-phase), Loose terminal block connections, Low or high line voltage, Internal power supply fault on module
How to Fix / Troubleshooting
Safety: Only a qualified electrician should work on mains connections. Disconnect power at the breaker before opening the terminal cover.
- Check installation: Compare the wiring at the cooktop terminal block with the Hotpoint-Ariston installation diagram. Ensure phase, neutral, and earth are correctly connected and links are fitted as specified.
- Tighten terminals: Inspect for loose screws or signs of overheating at the terminal block. Tighten all connections to the recommended torque.
- Measure supply voltage: With appropriate test equipment and training, measure the voltage at the terminal block. It must be within the range specified on the rating plate.
- Internal fault: If supply is correct and F17 persists, the internal power supply on the induction module may be defective and the module should be replaced.
