💡It may be difficult to remove the heat exchanger bar, due to a build-up of lime. If this happens you can descale the bar by running descaler through the group.
Use any descaler - make it strong and use the coffee switch on/off for a number of cycles. If water starts coming from the heat exchanger - then it is working and should loosen the bar.
Use a little silicon grease to insert the heat exchanger - it will make the job easier
