Rancilio tank cover assy b9 10701070

What is a water tank cover

The water tank cover is a plastic or metal part that covers the water tank in a coffee machine and protects it from dirt, dust, and unwanted contact. In some models, it is an outer cover visible when handling the tank, while in others it is an inner cover that holds the seal or valve in place and ensures the system closes correctly.

Typical signs of wear

A cracked, deformed, or poorly fitting cover allows dust to get into the water or causes limescale to build up faster. If the cover also holds the seal, damage may show up as water leaking near the tank, unstable closure, or an error message from the coffee machine about the tank being incorrectly inserted.

Why you shouldn't put off the replacement

A damaged cover can prevent the tank from sealing properly, leading to water seeping into the machine and risking damage to the electronics. Timely replacement also prevents the deterioration of coffee taste caused by contaminated water.

How to choose the right part

• Check compatibility in the table on the product page for your coffee machine model.
