Wallbox charger overheats; housing is very warm or hot and charging current is reduced or stopped, sometimes without a specific error code.

Safety first: If the unit is too hot to touch, stop charging and turn off the breaker until it cools.

• Improve ventilation: Ensure that the Wallbox has the recommended clearance on all sides and is not enclosed in a small, unventilated cabinet.
• Shade outdoor units: If installed in direct sun, consider adding a sunshade that does not block airflow.
• Internal terminal check (technician): With power off, open the unit and inspect all power terminals for signs of overheating. Tighten to specified torque and replace any discolored or damaged components.
• Reduce current: Temporarily lower the maximum charging current in the app to reduce heat generation, especially in hot climates.

If overheating continues after improving installation conditions, have a technician evaluate wiring size and internal components.
