Display shows Lo and the set temperature cannot be adjusted lower; unit may be in a lock or child-lock mode.

Safety: No internal work is required for basic unlocking.

Unlock procedure (typical BODEGA43):

• Press and hold the LOCK or LIGHT button (depending on model) for 3–5 seconds until the Lo indicator disappears.
• If there is a dedicated lock icon, press and hold the corresponding touch area until a beep is heard.

If Lo will not clear:

• Power cycle the unit by unplugging for 5 minutes.
• If buttons are unresponsive or stuck, the touch control panel may be defective and require replacement.
