Most Breville drip coffee makers have a descale or clean cycle, but the button sequence differs by model, so start with the manual for your exact machine. The general method is the same:
- Empty the carafe and remove the filter basket and any paper filter.
- Fill the water reservoir with a descaling solution, or with an equal mix of white vinegar and water up to the max line.
- Put the empty carafe on the warming plate, close the lid, and start the Clean or Descale cycle. If your model has no such button, start a normal brew cycle with the vinegar mix.
- When the cycle finishes, let the machine cool, then discard the liquid from the carafe.
- Run two or three full cycles with fresh water only to rinse out the vinegar taste and smell.
- Wash the carafe, filter basket and lid, and wipe the outside.
Descale about every one to three months, more often if your water is hard. Breville espresso machines use their own descale menu and Breville's descaling solution, so follow the on-screen prompts there, and check the manual before using vinegar in any espresso model.
What buttons do you use to start the descaling process?
I don't have a reliable button sequence for every Breville model, and they really do differ. Breville drip makers vary: some have a dedicated Clean or Descale button, others use a Clean light that you trigger by holding a combination, and some simply have you run a normal brew with the vinegar mix. The fastest way to get the exact steps is the manual for your model, which Breville posts on its support pages (search for your model number there). If you tell me the model name or number printed on the back or bottom of the machine, I can look up its specific sequence.
If it has no descale light at all, the vinegar method from my earlier steps still works: start a normal brew cycle with the vinegar and water mix, then run fresh-water brews to rinse.
Show me the most common button combinations to start the descaling process.
The most common combinations I found all apply to Breville espresso machines, not drip makers, so check that your model is one of these before trying them. Breville's own manuals are the authoritative source, and the sites below are secondary.
- Barista Express and similar (2 CUP + POWER): With the machine off, hold 2 CUP and POWER together until the POWER light flashes. Wait until POWER, 1 CUP, CLEAN/DESCALE and HOT WATER/STEAM all stay solid, then press 1 CUP to run the descale.
- Bambino and Bambino Plus (1 CUP + STEAM): Press and hold 1 CUP and STEAM together for 5 seconds to enter descale mode. Bambino guides list 2 CUP + STEAM for the same step, so check your model's manual.
- Barista Touch and Barista Pro (on-screen menu): Press the settings or menu icon, choose Descale or Descale Cycle, then follow the screen prompts. There are no button combinations to memorize.
The Barista Express manual on Breville's site (BES870 instruction book) covers the 2 CUP + POWER sequence. If you tell me your exact model, I can narrow this down. For a drip brewer, which I still can't confirm from these sources, the manual is the safest guide.
