  If the coffee crema is too light and being delivered too fast from your DeLonghi Coffee Maker, it could be due to: - The pre-ground coffee not being pressed down firmly enough: Press the pre-ground coffee down more firmly. - Insufficient pre-ground coffee: Increase the quantity of pre-ground coffee. - The pre-ground coffee being too coarse: Use pre-ground coffee specifically for espresso coffee makers. - Using the wrong type of pre-ground coffee: Change the type of pre-ground coffee. - Using the wrong filter with ESE pods: Only use the ESE filter.

  Jessica MooneyAug 17, 2025
  If espresso is dripping from the edges of the filter holder instead of the holes on your DeLonghi Coffee Maker, it could be due to: - The filter holder being inserted incorrectly: Attach the filter holder correctly and rotate firmly as far as it will go. - The espresso boiler gasket losing elasticity: Have the espresso boiler gasket replaced by Customer Services. - Blocked filter holder spouts: Clean the filter holder spout holes. - Too much coffee in the filter: Avoid over-exceeding the recommended dosage of coffee in the filter.
