Hear the sound of the engine often, plus it will need to work harder when it does:
The set temperature is colder than necessary
A large amount of hot food is fed into the device.
The room temperature is too high.
The doors have been left open for a long time or they open and close continuously.
After installing the appliance or if it has been switched off for a long period of time
The water tank (located at the bottom rear of the appliance) may not be correctly positioned to collect water, or the water spout is blocked.
You may need to remove the cooler from the wall to check the container and outlet pipe.
The LED light may be damaged. Follow the instructions in the section "Cleaning and maintenance".
The control system may have deactivated it because the doors have been open for a long time. Close and open the door
