If milk from your De'Longhi ECAM, ESAM or ETAM coffee machine is leaking onto the drip tray or under the appliance, and the milk container coupling no longer fits smoothly, worn milk system seals are the most common cause. The De'Longhi 15260 seal set is the correct replacement part for this fault — it includes seals located on the coupling between the milk container and the appliance, as well as on the milk container's outlet tube.
Important — check your model: before ordering, check the exact model designation and version (e.g. code EX:4) on the appliance's rating plate. The label is usually located on the bottom of the coffee machine or behind the water tank. These seals are designed for De'Longhi coffee machines with a milk system connected via a coupling. An incorrectly selected part may not fit, even if the model belongs to the same series.
When does this part need to be replaced? (Fault symptoms)
This part typically fails when you notice one of the following symptoms:
- Milk leaks or drips into the drip tray immediately after connecting the milk container to the appliance
- Milk appears under the coffee machine or around the milk container coupling after preparing a cappuccino or latte
- The milk container does not fit smoothly, holds loosely, or air escapes and milk splashes during frothing
- Milk froth is weak, thin, or uneven because the leaking coupling draws in air instead of milk
Compatibility: Which models is this part for?
This part is compatible with De'Longhi automatic coffee machines with a milk system connected via a coupling, within the following model series:
De'Longhi ECAM series
- ECAM series coffee machines with a milk container connected via a coupling
De'Longhi ESAM series
- ESAM series coffee machines with a milk container connected via a coupling
De'Longhi ETAM series
- ETAM series coffee machines with a milk container connected via a coupling
Exact model list: since milk system versions differ within the same series, compare the specific model designation (for example ECAM 22.360, ESAM or ETAM 29.660) with the details on your appliance's rating plate. If you are unsure, contact our technical support team and we will help you verify the part.
