Step-by-step repair guide

Step 1

⚠️ Caution: Unplug the power cord!

Remove all attachments such as water tank, pulp drawer, brew group.

Turn the machine with the back facing you.

Remove five Torx T20 security screws.

💡 Note: A small hurdle: These screws have a pin in the middle, so the screwdriver must have a hole.

Step 2

Lift out the back.

The following components are immediately visible:

grinder

pump

flowmeter

Step 1

Push the side panel back about 1.5 cm.

Lift off the panel.

The following compononents are exposed:

Heater

Expansion chamber

Gear drive

Steam valve

Step 1

Depending on the model, the steam tap/water spout must be removed, there are slight differences here.

Pull out the plastic clip on the steam nozzle.

Pull the steam nozzle out towards you.

Step 2

Carefully pull off the steam faucet toggle. Only use a plastic tool to pry to avoid damaging the bezel.

Step 3

If you haven't already done so, also detach the right-hand cover on the water tank.

Remove the four Phillips screws securing the top cover.

Lift the top cover up a bit. That might be a bit sticky.

💡 Note: Don't remove the top cover completely, some models still have cables attached to the cup warmer.

If there is a cup warmer, then unscrew the nut SW7 with which the two green-yellow cables are connected and loosen it. The two brown cables on the other side can stay if you just put the cover on top.

Place the top cover on top, or remove it entirely.

Step 1

The remaining front cover must also be removed.

Unscrew two screws on the left side.

Unscrew a screw on the right side.

Gently pull the front cover down. She might be a bit stuck.

Step 2

Remove the two screws on the control box.

Carefully lift the control box to one side.

💡 Note: Do not remove the box entirely, it is still connected with a ribbon cable. You can pull out the cable and put the box aside, possibly screwing it on loosely on one side.

Step 3

Remove the two screws on the coffee spout.

Lift off the coffee spout.

Pull off the silicone hose on the back of the coffee spout and remove the spout.

Step 4

The support of the upper piston is fixed with two screws on the left side. Depending on the model, these screws must be uncovered.

The first picture shows a model with an additional steam heater. Here the steam heater has to be unscrewed (one short screw on top, one further down), then it can be pulled out a few centimetres.

The second picture shows a model with a manual steam tap. Here the two screws on the tap must be loosened, then the steam tap can be pushed a little to the side.

Once the two screws are exposed, unscrew them.

Step 5

💡 Note: There are six connections on the upper brewing piston: three hot water pressure lines, one non-pressurized waste water line, a hose line to the coffee spout and two cables to the microswitch. All must be resolved first.

Pull out the clip at the top left and loosen the pressure line. Pay attention to the O-ring seal. It either hangs on the line or afterwards. When reassembling, replace it with a new one if possible.

Pull out the clamp in the middle and loosen the pressure line. Pay attention to the O-ring seal. It either hangs on the line or afterwards. When reassembling, replace it with a new one if possible.

Pull out the clamp on the bottom left and loosen the pressure line. Pay attention to the O-ring seal. It either hangs on the line or afterwards. When reassembling, replace it with a new one if possible.

Step 6

Disconnect the two flat connectors from the microswitch connection

Step 7

Take off the black bend protection on the middle pressure line.

Step 8

Unscrew the two Allen screws (4 mm).

Lift off the stainless steel bracket.

Step 9

Pull out the pressure hoses that are in the way through the openings on the left.

Detach any silicone hose that may be present.

The upper piston support plate is now free. However, it is very tight and it is tricky to get it out. Be patient and work carefully. Make sure that the ribbon cable to the control panel is not damaged.

Conclusion

Work the steps in reverse order to reassemble your device.

Frequently Asked Questions

How do I know if my DeLonghi ECAM upper brew piston needs replacing?

The most common sign is that no coffee comes out of your machine, but hot water still flows normally. This typically indicates the upper piston is clogged or worn and needs replacement. You can find the correct replacement upper brew piston for your DeLonghi ECAM model at Brewive.

What tools do I need to replace the upper brew piston on my DeLonghi ECAM?

You'll need a Torx T20 security bit with a hole in the center (to accommodate the pin in the security screws), a Phillips screwdriver, and a plastic pry tool to safely remove the steam faucet toggle without damaging the bezel. Brewive carries the replacement parts and can help ensure you have the right piston for your specific ECAM model.

Can I do this DeLonghi ECAM piston replacement myself, or do I need a professional?

This repair is doable for a confident DIYer, but it does involve disassembling several panels, removing security screws, and working around internal components like the heater and pump. As long as you unplug the machine first and follow the steps carefully, you can handle it at home. Brewive offers the replacement upper brew piston along with detailed guidance to support your repair.

Where can I buy a replacement upper brew piston for my DeLonghi ECAM machine?

You can purchase a compatible replacement upper brew piston directly from Brewive, which stocks parts specifically for DeLonghi ECAM series machines. Make sure to check your exact model number to ensure you get the correct fit.

Why do the back panel screws on my DeLonghi ECAM require a special screwdriver?

DeLonghi uses Torx T20 security screws with a small pin in the center, which prevents standard Torx bits from fitting. You'll need a Torx T20 security bit that has a hollow center to accommodate that pin. If you're ordering your replacement piston from Brewive, it's a good idea to have this specialized bit ready before you start the repair.
