Learn what to do when the pump in an ECM Elektronika II Profi espresso machine runs continuously while the machine is powered on.
If this happens, it means that the steam boiler is not filling. The pump will run for about 1 minute and then turn off. Turn off the machine and then turn it back on. If it times out again, there is a problem with the water flow.
- If the water leaks out of the top of the boiler, then the water sensing circuit is not working properly. It could be:
- Water sensor wire came of the sensor or the board
- You are using mineral free water. Sensors need minerals to operate.
ADVANCED TECH ONLY:
- Remove the wire off the fill probe and ground it out. Does the pump turn off?
- Yes. Raise the brew lever and see if water comes out of the brew group. If it does we know the pump and water circuit is working fine. The problem is probably in the steam boiler fill solenoid valve. It may be blocked or stuck.
- No. Check the wire leading to the probe and make sure it is on the board and has continuity. If the wire is fine it may be the board.
- If the autofill turns on after removing the wire from the probe, the boiler may already be full.
- Move on to the instructions listed in this machine's “Steam Boiler Not Heating, Not Steaming or No Hot Water At All” article.
- In very rare cases, an older machine with bad water and terrible maintenance will build scale up on the probe in the boiler, and scale is a poor conductor and can cause issues with the autofill circuit functioning properly. Also make sure the connector is tight on the water level probe. If it's too loose, use a pair of pliers to tighten the connector more. You can remove the water level probe and check it for scale. If scale is present you can use fine grit sandpaper to remove it.
