Troubleshoot low steam pressure on an ECM Classika PID.
Steam Pressure is Low
If you're trying to use your ECM Classika PID, and you find that the steam power is too low or insufficient for steaming or frothing, review the following to troubleshoot the issue.
- If you have flipped the steam switch and have given the machine at least 10 minutes to fully heat, check steam pressure. If the steam pressure is low, first remove the steam tip and inspect it to make sure it isn't blocked off from debris or old milk. If the steam pressure is still too low, have you changed any of the PID settings? It is possible to have accidentally turned down the steam value in the PID causing it to be too low. If you have changed the setting, you can refer to the PID service settings to return the machine back to factory settings.
- If you have not adjusted the PID in anyway, the upper cup warmer should be removed and the stat should be inspected to make sure it is not popped or damaged. A damaged high limit can prevent a machine from heating past a certain point. If it is popped the machine will not build steam pressure. Also inspect the non-resettable steam thermostat for damage and continuity.
- If all appears to be fine, the problem could be a result of a bad element, PID, static relay, or control board.
