What to do if my DeLonghi Heater doesn't work?
- AAdam LewisJul 29, 2025
If your DeLonghi Heater isn't working, first, ensure the temperature isn't set too low by setting it to a higher position. Next, verify that the heater is properly plugged into a working electrical outlet. Finally, check if the Key lock is activated.
