Why Regular Sanitisation Matters for Your Coffee Machine and Water Cooler
Most people only think about the quality of their coffee or water, but many don't consider what is happening inside the machine, which can have a significant impact on both taste and hygiene. Regular coffee machine and water cooler sanitisation is one of the most important, and most overlooked, aspects of machine ownership. We wanted to help explain why sanitisation matters and what can happen if you don't look after your machine.
Why Does Sanitisation Matter?
Machines that aren't regularly cleaned can develop a build-up of bacteria and limescale. This can directly impact the health of machine users, bacteria build-up is a genuine hygiene risk, which can spread throughout the machine if it is not dealt with promptly. But something many people don't consider is the effect it has on taste. Poorly maintained coffee machines and water coolers produce noticeably worse tasting drinks, regardless of the quality of the beans or water source.
What Happens if You Don't Sanitise Regularly?
Bacteria growth — particularly in water coolers where water sits and is dispensed frequently, creating conditions where bacteria can thrive
Limescale build-up — this can affect the performance and lifespan of your machine, reducing its efficiency over time
Poor tasting drinks — even the best coffee beans or water source can't overcome a dirty machine
Machine breakdown — poorly maintained machines are more likely to develop faults and require costly repairs
Voiding warranties — many manufacturers require evidence of regular coffee machine maintenance to honour their warranty
Slow dispense time — blockages in pipes caused by limescale or build-up can slow down the dispensing of drinks significantly
Tips for Day-to-Day Machine Maintenance
Wipe down surfaces daily — this helps prevent build-up on the outside of the machine and keeps surfaces in a hygienic state
Empty the drip tray regularly — making sure your drip tray is emptied at the end of each day, or when full, prevents water from going stagnant and milk from turning
Flush your machine at least once a week — not all machines feature automatic cleaning programmes, so knowing how to flush and maintain your machine on a weekly basis is essential for good coffee machine hygiene
Report any unusual tastes, smells or performance issues promptly — leaving issues unaddressed can make problems worse and harder to resolve in the long run
