Mechanical valve / piston for De'Longhi ECAM full-automatic coffee machines
If your De'Longhi ECAM series coffee machine has started directing water outside the cup, coffee is dripping very slowly, or you find a puddle under the machine, the cause is typically a worn mechanical valve (piston) De'Longhi 7313259921. This genuine spare part controls the mechanical movement and water flow toward the brewing unit and is the correct replacement to restore accurate pressure and water distribution in the hydraulic circuit.
Important — verify your model: before ordering, check the exact model designation and version on the rating plate (type label, usually on the underside of the machine or behind the water tank) to ensure this part fits. Note the full model code (for example ECAM610.55.SB) and the serial number — if in doubt, our service technicians are happy to help you confirm compatibility.
When does this part need to be replaced? (Fault symptoms)
This part typically fails when you observe one or more of the following symptoms:
- Water leaks into the drip tray or directly under the machine instead of into the cup
- Coffee flows very slowly, only in drops, or not at all
- The machine produces unusual hissing sounds during brewing due to pressure loss
- The spent coffee puck is wet and crumbles rather than holding a firm shape
If a General Alarm error related to the piston mechanism also appears, this is a further indication of a worn valve. Low pressure and water leaks are the typical signs of a faulty component of this type.

De’Longhi coffee machine – water leaks into the drip tray
With De’Longhi coffee machines, a common cause of water leaking into the drip tray is a damaged mechanical piston valve. This valve ensures proper water flow during coffee preparation. If the valve is worn, dirty, or mechanically damaged, the water flows into the drip tray instead of the cup.
The problem usually develops gradually – the coffee becomes weaker, less water flows into the cup, and the amount of water in the drip tray increases. This is often the result of long-term use, limescale buildup, or insufficient maintenance of the infuser.
The solution is to replace the mechanical piston valve. After replacement, the valve correctly regulates the water flow again and the coffee machine operates without leaks.
