What is the water tank and what is it for
The water tank is a component of the coffee machine that holds the supply of water needed to prepare coffee, as well as steam and hot water. Water is pumped from the tank to the boiler or directly to the brewing unit, so it must be sealed and undamaged for the machine to work reliably.
Signs of wear or damage
A cracked, leaking, or deformed tank can cause water to leak underneath the coffee machine, a reduced amount of water drawn in, incorrect functioning of the water level switch, or error messages about insufficient water. Sometimes the taste of the coffee can also worsen if deposits or odour build up in a damaged tank.
Why timely replacement pays off
A damaged tank can allow water to leak into the electrical parts of the coffee machine, increasing the risk of failure of other components. Timely replacement prevents unnecessary damage to the appliance and ensures smooth and safe preparation of beverages.
Selection advice
- Before purchasing, check the compatibility of your specific model in the product table.
- Check that the new tank fits into the coffee machine's compartment without needing any modifications.
- During installation, make sure the seals and water level sensors, if included with the part, are fitted correctly.
