How to Fix / Troubleshooting

Safety first: Turn off power at the breaker before opening the junction box or terminal cover.

Verify supply: Using a multimeter (only if you are qualified), check that the supply voltage at the cooktop terminal block matches the rating on the Asko data plate (typically 208–240 V AC).
Inspect connections: Remove the terminal block cover and check that all screws are tight and that wires are correctly landed on L1, L2, and Neutral/ground as per the installation diagram.
Look for heat damage: Replace any burned or melted terminal block and cut back and re-strip any overheated wire ends.
Module fault: If supply voltage is correct and connections are solid, the power board’s voltage sensing circuit may be defective and require replacement.

Never operate the cooktop on an incorrect voltage; this can cause permanent damage and safety hazards.

Cooktop displays F6 and will not allow operation of one or more zones.
