Deep cleaning a Delonghi La Specialista, how often is realistic?

[Thomas Martinez]

What's the general consensus on how often to deep clean a La Specialista? From what I understand, regular cleaning of these machine is essentially required in order to extract good espresso from them. Even machines that have been neglected for several year can be restored to good function with a deep clean.
There are step by step guides and video tutorials for those who would like to follow along with the deep clean with the machine. There are a few different area of the machine that need to be cleaned and completing the deep clean cycle in one go is the best way to ensure that the espresso machine will maintain it's excellent performance. Most people only perform the descaling procedure and wonder why the shots eventually begin to degrade in quality. A deep clean will fix that issues.

I typicaly deep clean mine every 3 months, but since I drink roughly 4-5 shots a day every 3 months, it might differ for peoples who only drink one shot a day out of the machine.

What people dont talk about is the grinder on the machine. While you can deep clean the rest of the machine all day long, if the grinder is full of grounds and fines your shots will never taste as good as they could. I typically remove the grinder burrs every couple months to clean them out. For hydraulic system deep cleans I do this every 2 months at the most since the water in my area is relatively soft. I also descale every 2 months since the water in my area is relatively hard. If you only do the descaling prompt on the machine you are missing out on 70% of the care that you should take of your La Specialista.

wait when you pull the burrs does the machine require a recalibration of the grinder?

The dial stays where it is but the grind seems to shift a little after reassembling the grinder. A single shot of espresso have to be pulled and the grind adjusted before using the machine again. Otherwise the grind generally isnt an issue as it shifts so slightly.

If your shots taste good and the steam is good then there's no reason to deep clean your machine. What an unnecessary ritual people has established into this hobby.

While I agree that steam and water flow should be monitored and addressed accordingly it's essential to deep clean the hydraulic system of the machine at least once a year and preferably every 4 months, even if you do deep cleans every couple months to address the solenoid and shower screen. Addressing the hydraulic system is necessary because otherwise the scale will build up in areas that are difficult to access. One time my machine was neglected for 14 months and when I attempted to deep clean the hydraulic system the shower screen gasket was essentially fossilised along with gunk in the three-way valve. After an afternoon and some cursing I was able to restore it to working order. Since then I've established every 4 months to maintain the machine and ensure my shots tastes better. While there are various YouTube videos out there to deep clean your machine the quality of them vary. Some of them completely skip the brew group which is one of the most important parts of the deep clean. The deep clean I use is from the channel Whole Latte Love and the official Delonghi service document on deep cleaning.
