Descaling the Gaggia Classic Evo Pro
Descaling clears mineral scale from the single aluminium boiler and water path. How often depends mostly on your water hardness - soft or filtered water means far less often.
Every 1–3 months, sooner on hard water
| Soft / filtered water | Every 3–4 months |
| Medium-hardness water | Every 1–2 months |
| Hard water | Every 3–4 weeks |
Check your manual: These intervals are general guidance. Always follow the descaling procedure and interval in your Gaggia Classic Evo Pro manual - your local water hardness determines how often you actually need to descale.
Step by step
- Empty the drip tray and water tank, and remove the portafilter.
- Fill the tank with descaling solution (or a citric-acid mix) at the ratio on the bottle.
- Run solution through the brew group and the steam wand in batches, then switch off and let it sit briefly, as described in your Gaggia manual.
- Refill with fresh water and run two to three full tanks through the group and wand to rinse before brewing again.
- Avoid vinegar - it can degrade internal seals. Use a descaler made for espresso machines.
- Scale builds up in the aluminium boiler over time - don't skip descaling on hard water.
What you'll need
- Espresso-machine descaler or citric acid
