3Inspect the O-ring groove.

Grains of sand or hardened salt sometimes get into the groove. Carefully remove them by blowing with an air spray or by wiping them with a cotton wool bud. Prevent fibre scraps from the cotton wool bud from entering inside.

4Also, inspect the contacting surface on the other side of the O-ring in the same way.
