Water tank for Delonghi ECAM 26/28/510 coffee machines

What this water tank does

This water tank is designed for Delonghi ECAM 26/28/510 coffee machines. It holds the fresh water supply that feeds the boiler and brewing group, and it lifts out from the machine so it can be filled, rinsed and refitted with ease. A properly seated, intact tank is essential for consistent water flow and reliable extraction.

Signs it needs replacing

Over time a water tank can develop cracks, cloudiness, warped edges or a loose-fitting lid, all of which may cause leaks, poor sealing, or the machine failing to register that water is present. A damaged valve or connector at the base can also stop water from reaching the pump correctly, triggering error messages or interrupted brewing cycles.
