Quick Assessment

Answer to continue safely

Is it safe to keep using?

Maybe. Unaffected zones are safe to use. Avoid using the faulty zone as it may behave unpredictably.

Can I reset the code?

Yes. A power cycle may temporarily restore communication. Hardware faults will cause the error to return.

When to stop immediately?

Stop if you notice: Zone heats erratically or at wrong power level, Multiple zones lose communication.

Symptoms You May Notice

Touch controls respond but zone does not heat

The display acknowledges touch input but the selected cooking zone produces no heat.

Zone power fluctuates unpredictably

The cooking zone alternates between full power and no power during use.

Error appears on one zone only

Possible Causes

1

Communication bus fault

The data connection between the interface board and the zone power module has a break or high-resistance point.

2

Zone power module failure

Requires Professional

Safe Checks You Can Do

  1. 1

    Power cycle the cooktop

    Turn off the breaker for 5 minutes and restore power. Test the affected zone.

    A temporary communication glitch may clear with a full power cycle.

  2. 2

    Test all zones

    After reset, test each zone one at a time to identify which zone has the communication fault.

    If all zones fail, the interface board is likely the issue. If one zone fails, that module is faulty.
