The best tablet is the one your machine actually allows.
Cleaning tablets remove coffee oils. Descaling tablets remove mineral scale. We separated the two jobs, checked the current maker codes and built a safer UK shortlist.
Updated 2 August 2026 · Desk research using manufacturer documentation · No hands-on product rankingA coffee-oil tablet is not a descaler, and a descaler is not a brew-group cleaner. The manual for your exact machine—and its stated product code—wins over any “universal” claim.
Fit before price, pack size or popularity.
These are not claimed performance winners. We prioritised current products with clear manufacturer instructions, identifiable codes and a sensible UK buying route.
Amazon buttons open a search for the named product because sellers, pack sizes and stock change. Confirm the exact code and seller before buying.

De’Longhi owners may need a liquid, not a tablet.
De’Longhi specifies EcoDecalk liquid for its coffee machines and says the liquid format is easier and faster to dissolve than tablets. Do not buy a tablet merely because that was your original search term.
Check the official EcoDecalk guidance →What should I buy for my machine?
BEC250UK for coffee oils; use the Sage-approved descaling product specified for the model.
3-phase cleaning tablet for the clean programme; 2-phase descaling tablet when the machine requests it and filter settings permit.
00312295 cleaner and 00312574 descaler only after checking the appliance E-Nr.
CA6704/10 for coffee oils; use the exact Philips descaling product and sequence specified for the model.
Do not force a tablet choice: De'Longhi specifies EcoDecalk liquid for its machines.
