Descaling Alert
Philips Saeco Coffee Machine
Severity:What Does This Error Mean?
The descaling alert means scale has built up to a level that requires a full descale cycle. Use Philips descaler liquid (CA6700) and the built-in descale programme. The process takes around 30 minutes.

Common Causes
- Scale buildup in the boiler and water circuit from hard water
- AquaClean filter expired or not installed, allowing more scale to form
- High local water hardness accelerating mineral deposit buildup
How to Fix It
-
Purchase Philips descaler liquid.
Use Philips CA6700 liquid descaler or an equivalent citric-acid-based descaler. Avoid vinegar — it can leave residual taste and may damage internal rubber seals.
-
Prepare the machine.
Empty the drip tray and water tank. Mix the descaler with water in the tank as directed on the product (typically one sachet or bottle cap into a full tank). Place a container of at least 1.5 litres under the spout.
-
Start the descale programme.
Navigate to Maintenance or Settings and select Descale, or hold the relevant button combination (check your model's manual). The programme runs automatically in several phases — do not stop it once started.
-
Complete the rinse phase.
When prompted, empty the tank, fill with fresh water, and continue. The machine will run a clean-water rinse to flush out all descaler residue. The alert resets when the cycle is complete.
When to Call a Professional
Descaling is a routine user maintenance task. If the descaling alert returns within a short time of completing a full cycle, contact Philips support.
