How often should i descale my coffee machine

Follow Your Machine's Descale Reminder
Many modern coffee machines monitor usage and will tell you when descaling is due.
Engineer's Tip: Always complete the full descaling programme when prompted rather than delaying it for several weeks.
Consider How Much You Use Your Machine
A machine making two coffees a day has very different maintenance needs to one preparing ten or more drinks daily.
Engineer's Tip: The more frequently you use your machine, the more often you'll need to descale and perform routine maintenance.
Water Hardness Makes a Difference
Hard water contains more minerals, which can form limescale inside your coffee machine more quickly.
Engineer's Tip: If you live in a hard water area, expect to descale more often than someone using soft or filtered water.
Use a Water Filter if Recommended
Many bean-to-cup coffee machines are designed to work with water filters.
A filter can help reduce limescale build-up and improve water quality.
Engineer's Tip: Remember that filters reduce scale—they don't eliminate the need for descaling completely.
Don't Wait for Performance Problems
A machine doesn't have to stop working before it needs descaling.
Slower brewing, louder pump noise or cooler coffee can all be early signs that scale is beginning to build up.
Engineer's Tip: Preventative maintenance is usually much easier than dealing with scale-related faults later.
Complete the Entire Descaling Programme
Stopping the programme early or missing the rinse cycles can prevent the machine from resetting its maintenance reminder.
Engineer's Tip: Allow the full descaling and rinse programme to finish before switching the machine off.

How often should I descale my coffee machine?
There isn't a fixed schedule that suits every owner. Most machines either monitor usage automatically or provide guidance in the manual. Factors such as water hardness, daily drink volume and whether you use a water filter all affect how often descaling is needed.
Can I descale too often?
Routine descaling using a coffee machine descaler is part of normal maintenance. There's generally no benefit in descaling far more often than necessary, but delaying descaling for long periods can allow limescale to build up and affect performance. Follow your manufacturer's recommendations and adjust your maintenance to suit your usage.
What happens if I never descale my machine?
Limescale gradually reduces water flow and heating efficiency. Over time this can lead to slower brewing, cooler coffee, increased pump noise and, in some cases, expensive repairs that regular maintenance may have helped prevent.

Heavy Daily Use
Signs
- Several coffees every day.
- Frequent milk drinks.
- High household usage.
Recommendation
Increase the frequency of routine maintenance and complete the descale programme whenever prompted.
Hard Water Area
Signs
- White limescale around taps or kettles.
- Faster scale build-up.
Recommendation
Use a compatible water filter where recommended and expect more frequent descaling.
Reduced Water Flow
Signs
- Coffee pours more slowly.
- Less hot water.
- Pump sounds louder.
Recommendation
Complete the manufacturer's descaling programme before investigating other faults.
Cooler Coffee
Signs
- Drinks gradually become less hot.
- Brewing takes longer.
Recommendation
Descale the machine to remove limescale affecting heating efficiency.
Descale Reminder Displayed
Signs
- Warning light or display message.
Recommendation
Complete the full descale programme as soon as practical.
Long Time Since Last Maintenance
Signs
- You can't remember the last descale.
- Machine has had heavy use.
Recommendation
Complete a descale cycle and establish a routine that matches your own usage.
