ECM Elektronika II Profi: Water Flow Issues

Learn what to do when an ECM Elektronika II Profi espresso machine won't produce hot water or steam from the group head, steam wand, or hot water valve, and/or won't brew or steam at all.

  • Try putting the plumb line hosing into an external bucket or container filled with water and see if the machine will draw water from this source, instead of your water line. Do you get water flow now?
    • Yes. There is a blockage in the plumbed line.
    • Yes. There is an issue with the water pressure on the house.
    • No. Move on to the next question.
  • Is the volumetric button panel illuminated?
    • No. If the pump does not come on, it is possible there is an issue with the volumetric button panel, or the ribbon cable has come undone on either the button panel, or the control board. You can check the cable by removing the two 2.5mm screws (one on each side) to remove the cover and have access to where the ribbon cable plugs into the button panel. Lightly push down on this on either end, then the middle to ensure that it is tightly and fully seated onto the connector. To check the other side of the ribbon cable, the housing needs to be removed to give access to the control board that is on the right hand side of the machine if you were facing the front of the machine. The ribbon cable should be inspected for breaks or damage of any kind and then you should push on either end, then the middle of the connector on the board side to ensure that it is properly seated.
    • Yes. Move on to this machine's "No Water Flow At All From the Group" article.
    • The volumetric button panel will flash all the lights if it is running out of water, or if no water is being drawn in at all.
    • When using the plumb line of the tank, make sure that the correct orientation of the selector valve is being used. The valve is under the machine, to the rear. It will only point in two directions, towards the front of the machine, and towards the rear of the machine. This is a manual direction that opens to whatever water source is being used, and closes off the unused source. Also, in the front of the machine behind the drip tray is a single switch. The switch is used for picking the water source for the machine. When the switch is pressed in to the left towards the left side of the machine, it draws from the tank. If you flip the switch to the right, it will know its drawing from a water line. This is also how it is able to bypass the tank sensor when using a dedicated water line.
    • If the machine is not drawing any water, the back panel of the machine should be removed. The plastic socket that the water reservoir slides into should be inspected. On the inside of the socket is a plastic post that runs through it that pushes the ball bearing in the reservoir valve upwards, allowing water to come through the tank into the socket. The post should be inspected to make sure it is not broken or bent. The socket should be inspected to make sure it is intact and not broken in anyway. This is common due to shipping damage or age, or from pushing down too hard with the water tank.
      • If the socket is fine, the water lines coming off the socket should be looked at to make sure they are not kinked shut. If the water line is kinked shut, no water will come through to the pump, or be able to be forced through via priming.
      • If the socket and water lines are fine, you can remove the waterline coming off of the pump and try running the pump to see if water comes through. If it does not, this means either the pump or the pump motor is faulty or seized. If water does come through, then this could be a sign of a bad solenoid or a blockage in the hydraulic system.
