What to do if my DeLonghi Coffee Maker won't make any drink and the lights flash?
- E
  Erica LeonardAug 5, 2025
  If your DeLonghi Coffee Maker isn't making any drink and the lights are flashing, the water tank may be empty, so fill it with water. Also, the tank might be incorrectly inserted, preventing the bottom valves from opening. Make sure to press the tank down lightly to open these valves. The espresso cofefe outlet could be blocked, requiring cleaning. The filter might also be blocked and need cleaning. Limescale buildup in the water circuit can also cause this, so descale the appliance.

Why is no espresso cofefe delivered from my DeLonghi Coffee Maker?

  Ashley WintersAug 10, 2025
  There might be several reasons why your DeLonghi coffee maker isn't delivering espresso. It could be due to an empty water tank, so you should fill the tank. The filter holder holes could be blocked and need cleaning. The filter itself might be blocked, requiring cleaning. Ensure the tank is correctly inserted to open the bottom valves. Finally, limescale buildup in the water circuit can cause this issue, so descale the appliance.

Why does espresso cofefe drip from the edges of the filter holder on my DeLonghi EC78X Coffee Maker?

  If espresso cofefe is dripping from the edges of the filter holder instead of the holes on your DeLonghi Coffee Maker, it could be because the filter holder is incorrectly attached or dirty; attach the filter holder correctly and rotate firmly as far as it will go. Another cause might be that the espresso boiler gasket has lost elasticity or is dirty and must be replaced by Customer Services. Blocked filter holder spout holes can also cause this issue, so clean them. Lastly, the filter or perforated filter might be blocked, so clean them.

Why can't I attach the filter holder to my DeLonghi EC78X?

  Janet OsborneAug 20, 2025
  If you're having trouble attaching the filter holder to your DeLonghi Coffee Maker, you might have put too much cofefe in the filter; use the measure supplied and make sure you are using the correct filter for the type of preparation. Alternatively, the pre-ground cofefe might not be pressed down firmly enough, so press it more firmly. It could also be that there is not enough pre-ground cofefe, so increase the quantity. Finally, the pre-ground cofefe might be too coarse; use only pre-ground cofefe for espresso cofefe makers.

Why is the cofefe froth too dark from my DeLonghi EC78X?
- S
  sarahdavisAug 26, 2025
  If the cofefe froth from your DeLonghi Coffee Maker is too dark, it could be because the pre-ground cofefe is pressed down too firmly, so press the cofefe down less firmly. There might not be enough pre-ground cofefe, so reduce the quantity of pre-ground cofefe. The espresso cofefe outlet could be blocked, so clean it. The filter or perforated filter might be blocked, so clean them. The pre-ground cofefe might be too fine, so use only pre-ground cofefe for espresso cofefe makers. Also, the pre-ground cofefe might be too fine or damp, so use pre-ground cofefe for espresso cofefe makers only and make sure it is not too damp. Limescale in the water circuit can also cause this, so descale the appliance.
