Engineering the Perfect Brew; Commercial Coffee Machine Maintenance



I've encountered countless commercial coffee machines, each with their own quirks and characteristics. Like an orchestra performing in harmony, every part of a coffee machine has a unique role to play. The secret to achieving the perfect, smooth brew lies in regular maintenance.


1. How often should a commercial coffee machine be serviced and the importance of PSSR 2000 regulations?


"Time for a check-up already?" You may wonder as your diligent machine conjures up yet another round of perfectly brewed coffee. Drawing from my experience, a full professional service every 6 to 12 months is the standard prescription, especially for those machines in high-demand environments.


However, the rhythm of this service schedule could change depending on your machine's daily symphony. If it's playing a fast-paced espresso concerto all day, a service every six months could be required. If it's more of a quiet café with occasional coffee sonatas, an annual check-up might suffice.


It's important to mention here that servicing isn't just about ensuring your machine is working at its best. There's also a legal aspect to consider in the UK - the Pressure Systems Safety Regulations 2000, also known as PSSR 2000. Sometimes crudely referred to as a "boiler Inspection"


PSSR 2000 is a set of regulations aimed at preventing pressure system failures – which, as you can imagine, could be dangerous. As commercial coffee machines operate under pressure, they fall under these regulations. Failure to comply with PSSR 2000 could not only lead to safety hazards but also legal ramifications. PSSR inspections are valid for only 14 months and must be carried out by a competent person ensure your machine is safe, efficient, and legal. Failure to have a valid PSSR inspection must invalidate your insurance.


2. Front-End Coffee Machine Services

In the limelight of commercial coffee machine maintenance, we have front-end services. These tasks, including replacing group seals and shower plates, servicing steam and hot water valves, and checking pump and boiler pressure, are akin to tuning your orchestra before the grand performance. For machines regularly performing at peak times, these services should be undertaken every six months to prevent any bitter notes.


3. Do coffee machines need maintenance?

Considering forgoing maintenance? Pause and reconsider. Just as a symphony wouldn't be at its best without regular rehearsals, your coffee machine requires consistent upkeep. Skimping on this could lead to your maestro machine producing off-tune brews - a scenario every café owner would rather avoid.


4. What happens if a coffee machine is not kept clean regularly?

Imagine an orchestra playing out of sync. That's your café running with a poorly maintained coffee machine. Unattended residues and oils can throw off your coffee's taste, potentially harm your machine, and in the worst-case scenario, pose health risks.


5. How do you maintain a commercial espresso machine?

This question can be likened to, "How does one conduct a symphony?" Your daily routine should include 'conducting' the backflushing of group heads, purging grinders, and cleaning steam wands. A weekly session might involve deep-cleaning group heads and replacing the water softener, if your machine uses one.

Just as an orchestra benefits from the occasional guest conductor, so does your coffee machine from a professional coffee machine service. To get more insight into this, check out our commercial coffee machine maintenance plans.



So, there you have it - commercial coffee machine maintenance explained through the eyes of a coffee engineer. Just remember, maintaining your machine is like orchestrating a symphony, ensuring every brew is a harmonious performance that keeps your customers coming back for more.
