Ceramic electric hob shows Er01 and does not respond to touch controls.

Safety first: Turn off the hob at the mains if there is any sign of smoke or burning smell.

• Remove objects: Clear any pans, cloths, or utensils from the control area.
• Clean and dry: Wipe the glass thoroughly to remove moisture and grease.
• Power cycle: Switch off at the breaker for 5 minutes, then restore power and test.

When to call a technician: If Er01 persists on a dry, clean panel, the touch control board may require replacement.
