Introduction

Be careful when disassembling the tubes and connections. They may be tightly attached to the machine and may take some effort to remove.

    • Flip open the top panel to reveal water reservoir.

    • Grab the water reservoir by the handle and lift out.

    My model EC155, serial #43222 requires a Security Torx vs. a #2 Phillips to remove the 12mm screws at each corner of the bottom panel

    • Flip the device on its head.

    • Using the Phillips #2 screwdriver, unscrew the four 12 mm screws found at each corner of the bottom panel.

    • Lift the panel off or flip the device over and let the panel drop out.

    At least on my unit, those screws weren't Phillips, but Torx Tamperproof T20! Shame on you, De'Longhi!

    • Before flipping the device, removed the black container and grill.

    • Flip the device on its head, front end facing you.

    • Using the Phillips #2 unscrew the two 52 mm screws found underneath the top portion of the device.

    the tip about removing the black container and grill should be before step 2.

    • Flip the device back to its proper orientation.

    • Using the Phillips #2 screwdriver remove the two 52 mm screws found on the lip next to the reservoir.

    • Insert the two plastic opening tools beneath the top knob.

    • Use the two plastic opening tools as leverage to lift the top knob off.

    • Grasp the lid firmly with both hands.

    • Pull mightily with both hands away from the device.

    • If you hear a slight snapping sound, it is supposed to do that.

    • Use a plastic opening tool to push in the slot on the back panel while lifting.

    • Similarly, reach into where the reservoir used to be and insert a plastic spudger underneath the inside panel.

    • We recommend to not use your fingers for this step because there is a chance they will be pinched.

    • You are now ready to lift the top off.

    • Place one hand near the back, the other at the front, and lift.

    • You may want to lift the front and back individually by pulling one a little off the part before the other. Afterwards, lifting the top off entirely will be easier.

    • Flip the device and remove one end of the tube from the water reservoir hole.

    There are two tubes connected to the water reservoir hole. The one in the first pic is the one that goes to the water valve, which is the one that you pull through to the top. The one in the second pic is the short one from the bottom of the pump that can detached from the water hole and left in place, to be transferred later to the new pump. Detaching it from the from the filter as shown adds to the impression that this is the tube to the water valve to be pulled through to the top in the next step, which the user quickly finds is impossible, it’s too short.

    • Pull the tube through the chamber with the water pump so it comes out of the top end.

    • Twist the valve counterclockwise while pulling gently.

    • Twist the frother clockwise while pulling gently.

    • Remove the four 16mm screws with a T20 Screw head.

    • Remove each clip from the valve and core using the precision angled tweezers.

    My deLonghi failed by leaking from this connection (after years of operation). After a failed attempt with what I was told was an OEM o-ring, I successfully repaired it with a "Silicone O-Ring, 7mm OD, 3mm ID, 2mm Width, VMQ Seal Rings Gasket" from Amazon. (I used a dental pick to pull out the old ring.)

    This is the standard o-ring, as used e.g. in Jura devices.

    • Pull out each LED with one quick tug.

    • Similarly, remove each set of wires from the setting tuner with one quick tug.

    It’s better to keep the wires in place and remove the whole setter switch by prying off the knob, then removing the two screws exposed I was unable to remove the core your way because of the difficulty of getting past the setter switch, especially since at the same time you have to wrangle with getting the steamer wand out, even with the frother removed.

    Also, your pic shows four wires to disconnect, there are actually five, and there’s no view of which of them go where—another reason for keeping them connected.

    • Flip the device and remove one end of the tube from the reservoir hole.

    • Completely remove the other tube from both the reservoir hole and filter to the water pump.

    • Pull the tube through the chamber with the water pump so it comes out of the top end.

    • Twist the valve counter-clockwise while pulling gently.

    • Tilt the core towards the front while lifting from the back.

    • If the core is proving difficult to remove, a wire might be caught somewhere, likely near the water pump. We recommend shaking slightly as you lift since the frothing tube is at an odd angle.

    • We also recommend that you remove the valve before removing the core so that there is less obstructing movement. But the core can be removed without removing the valve.

    Pushing to the front is impossible at first if the settings switch is still in place (see earlier comment).

    Also, it’s worth mentioning that the steaming wand *will* come out with the right twisting and turning of the core. I got stuck her trying to figure out how to detach it from its hose. But the attachment is permanent. This is what led me to buy more maneuvering room by removing the settings switch with wires still attached.

    • Remove both sets of wires from the black box of the water pump.

    • Cut off the zip-tie holding all the wires together.

    • Isolate the blue wires from the rest and remove from core as necessary.

Conclusion

To reassemble your device, follow these instructions in reverse order.
