There isn't one schedule that suits every coffee machine owner. How often you should descale depends on your water hardness, the number of drinks you make and your machine's recommendations. If your machine has a descaling reminder, always follow it. Machines used more frequently or in hard water areas may need descaling more often.

Always use a descaler that is suitable for coffee machines and follow the manufacturer's instructions. Avoid household cleaners, bleach or vinegar unless your manufacturer specifically recommends them, as these can damage seals or leave unwanted residues.

Limescale gradually builds up inside the water system, restricting water flow and reducing heating efficiency. Over time, this can lead to slower coffee preparation, cooler drinks, increased pump noise and, in some cases, expensive repairs that could have been avoided with regular maintenance.

Many coffee machines only clear the descale reminder after the complete descaling programme has been followed, including all rinse cycles. Interrupting the programme or switching the machine off early may prevent the reminder from resetting. If the message remains after a full cycle, consult your machine's support guide.

Yes, if limescale is causing the restriction. Descaling often restores normal water flow, improves brewing temperature and helps the machine perform as intended. However, if the problem continues after descaling, another fault may be present and further troubleshooting may be required.

Using a water filter where recommended, replacing it regularly and following your machine's maintenance schedule can help reduce limescale build-up. The frequency of descaling will still depend on your local water hardness and how often you use your coffee machine, so adjust your maintenance routine to suit your own usage.
