How often do you find that you service your espresso machine?
Of course the answer is "well, it depends..."
But say, for the average Home Barista, you prep a drink for you and your spouse, sidekick, or other once a day for an average of say 500 a year?
How often do you feel compelled to service the unit?
How much do you spend on the typical visit to the tech?
Do you service the group/shower head yourself and leave the electricals to the pros?
Does it change depending if the machine is a light commercial GS-series, Rocky, Rancilio, etc or a consumer Saeco, Breville, etc machine?
Consensus at my workplace is about 3 a year. Is that high, low or about average?
