Question 2

What should I do if my NUK Vario Express bottle sterilizer is not working?

Accepted Answer

If your NUK Vario Express bottle sterilizer is not working, here are several steps to follow to try to resolve the issue:

1. Check the power supply

Make sure the device is properly plugged into a functioning electrical outlet.
Test the outlet with another device to confirm it is working.

2. Inspect the power cord

Examine the cable for any visible damage, such as cuts or tears.
If the cord is damaged, it must be replaced before reusing the device.

3. Check the water level

Ensure that the tank contains enough water, as a low level may prevent the sterilizer from functioning.

4. Clean the device

Limescale or residue may hinder proper operation. Clean the sterilizer according to maintenance recommendations, especially the tank and surfaces in contact with water.

5. Reset the device

If your model has a reset button, press it.
If not, unplug the device, wait a few minutes, and then plug it back in.

If after these checks the sterilizer still does not work, it is advisable to contact NUK customer service for further assistance or repair.
