    • The right side panel is removed in the same way, but the service hatch is a bit obstructive. Open it first and push the side panel back a few millimeters. This is often difficult and you will need a plastic lever tool.

    • Close the flap again and push the sides further back. It is a bit tricky and you have to work carefully. Lift out the side panel.

    • The top is fixed with screws on the left and right, depending on the type. Unscrew them.

    • Now the top can be gently lifted off.

    • Depending on the type, it is shaped differently. Some have the control panel far to the rear. Leave it for now, it is connected with cables.

  10. DeLonghi ETAM series upper brewing piston replacement, DeLonghi ETAM series control panel removal: step 10, image 1 of 1
    • The control panel is locked very tightly with four catches on the front. It is tricky to release these latches and you need quite a lot of force.

    • First loosen the detent on the edge. Use a thin flat-blade screwdriver to drive under the latch from behind. Insert a strong plastic lever tool into the gap between the control panel and the front. The latch opens with a loud crack.

    • Now you can open the other latches with the lever tool

    • Do not remove the control panel completely yet, it is still connected with cables.

    • Lift up the control panel a little. Press the latch on the white plug and pull off the plug.

    • Unthread the ribbon cable that leads to the control electronics at the back as far as possible. This will make it longer and you can place the control panel on its side.

    • If you want to remove the control panel completely, you have to take off the cover on the control electronics and disconnect the connector. Then you can unthread the cable completely.

    • 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 removed first.

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

    • Pull off the hose to the coffee spout.

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

    • 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.
