If your espresso machine cannot get the coffee out of the machine, you can check the following:

• The error may be due to the beans being ground too finely, so that the water cannot come out of the espresso machine. Run a coarser setting.
• The error can be caused by a scaled espresso machine. Descaling the espresso machine to solve the problem.
• If water comes out of the espresso machine but no coffee comes out, it is most likely that the brewing tower is dirty. Cleaning the brew tower should make the coffee run out again. If the coffee does not come out after cleaning the brewing tower, it may be because the brewing unit is defective. One of the symptoms would be that the water is hot.
• If the water that comes out of the espresso machine is cold and you have cleaned the brewing tower, it may be due to a faulty heater or a faulty thermostat.
• If the above steps have not solved the problem, it may be due to a defective pump.
