How to maintain London coffee machines for better taste, hygiene & performance

Coffee machines are one of the most heavily used pieces of equipment in any workplace. In busy London offices, commercial coffee machines operate all day, every day, which means regular cleaning and descaling isn’t optional, it’s essential.

At The Jar Healthy Vending, we supply, install and maintain London coffee machines across offices, co-working spaces and commercial venues. Proper maintenance protects your investment, improves hygiene standards and ensures consistent coffee quality for your team.

Here’s everything you need to know about cleaning, descaling and servicing office coffee machines in London.

Why regular cleaning of London coffee machines matters

Coffee machines handle water, milk and coffee oils daily. Without proper cleaning, residue builds up quickly, leading to:

• Bitter or inconsistent coffee taste

• Blocked internal components

• Reduced machine lifespan

• Hygiene concerns

• Increased energy usage

  
  

Milk systems require particular attention. In high-traffic London workplaces, uncleaned milk lines can harden and harbour bacteria, affecting both flavour and safety.

Regular cleaning ensures your London coffee machine continues delivering quality coffee while preventing avoidable breakdowns and downtime.

How often should you descale London coffee machines?

Descaling removes limescale, a mineral deposit caused by hard water. London is known for having hard water, which means limescale builds up faster than in many other regions of the UK.

For most commercial coffee machines in London:

• Light use: Descale every 3–4 months

• Medium to heavy office use: Every 1–3 months

• Bean-to-cup commercial machines: Follow manufacturer guidance and servicing schedules

  
  

Ignoring descaling can result in:

• Slow heating times

• Reduced water flow

• Higher energy consumption

• Internal damage

  
  

Over time, this can lead to costly repairs or even complete machine failure. Many modern London coffee machines include automatic descaling alerts but in high-use environments, proactive servicing is always recommended.

Signs your London coffee machine needs maintenance

Even well-maintained machines will show early warning signs when something isn’t right. Look out for:

• Coffee tasting burnt or unusually weak

• Longer brewing times

• Reduced steam pressure

• Unusual noises

• Water leaks

• Error messages

  
  

Addressing these issues early prevents larger mechanical failures and extends the lifespan of your workplace coffee machine.

Why professional servicing of London coffee machines is important

While daily cleaning can be handled in-house, professional servicing is essential for maintaining commercial coffee machines in London offices.

A professional service typically includes:

• Deep internal cleaning

• Full descaling

• Filter checks and replacements

• Calibration adjustments

• Safety inspections

• Inspection of wear-and-tear components

  
  

This proactive approach reduces breakdown risk, improves efficiency and extends the operational life of your machine.

For busy London workplaces, downtime isn’t just inconvenient, it affects productivity, employee satisfaction and client experience. Regular servicing ensures your coffee solution remains reliable and consistent.
