Klarstein coffee maker’s water tank is difficult to remove or leaks at the connection point.

Safety first: Unplug before handling the tank area.

Cleaning and inspection:

• Remove the tank and clean the outlet valve and surrounding area with warm water and a soft brush.
• Inspect the rubber seal or O-ring for cracks or flattening; replace if worn.
• Check the machine-side connector for scale and clean gently.

If the tank body or locking tabs are cracked, replace the entire water tank with a Klarstein-compatible part.
