DeLonghi Coffee Machine Descaler 500ml – 12 Pack (DLSC500)
Every espresso machine builds up limescale from the water running through it. Left alone it slows the flow, cools the brew temperature, makes the machine noisier and eventually blocks the boiler – and scale damage is not covered by most warranties. Descaling on schedule is the single cheapest thing you can do to keep a machine alive.
This is the 500 ml DeLonghi descaler (DLSC500) in a 12-bottle carton – the sensible buy for a workshop, office, or anyone who would rather not reorder every few months.
Why descale
- Coffee tasting flat, sour or cooler than it used to
- Slow or uneven water flow through the group
- Machine running louder, or the pump straining
- Descale warning light or prompt showing on the machine
- Scale visible in the water tank or on the shower screen
How often
Most DeLonghi machines prompt you when a descale is due, and the interval depends on how hard your water is and how much coffee you pull. In hard-water areas across Brisbane and the Gold Coast, machines typically call for it more often than the manual suggests. If your machine has a descale light, follow it – if it does not, every two to three months is a safe rule for daily use.
What it suits
Formulated for DeLonghi coffee machines, and suitable for most other domestic espresso machines that call for a liquid descaler. Always follow the descaling procedure in your machine’s manual.
