Wolf range or cooktop display shows E17 and some or all functions are disabled after a power outage or surge.

Safety first: Turn off power at the breaker before any disassembly.

• Power cycle: Turn the breaker off for 10 minutes, then back on. This can sometimes clear transient memory errors.
• Check installation: If a control board was recently replaced, verify that the correct Wolf part number was installed and that any required configuration steps (model code entry, calibration) were completed per the service manual.
• Surge protection: If the error followed a storm or outage, consider installing a surge protector on the appliance circuit to prevent future damage.
• Board replacement: Persistent E17 usually indicates a failed control board that must be replaced and programmed by a Wolf-authorized technician.
