Leaking hot water or steam from damaged percolator components

Possible cause: Cracked, loose, or damaged components or rubber gasket. Check every part before use and don't use it if anything's cracked, loose, or damaged - and make sure the rubber gasket is intact and fitted correctly.

Clogging in the coffee filter basket

Possible cause: Obstructed holes in the coffee filter basket. Clear the holes with a soft-bristled brush or a needle.

Clogging or blockage in the pressure valve

Possible cause: Limescale formation caused by regular use of drinking water. Mix equal parts water and vinegar or citric acid, enough to cover the pressure valve, leave it for 1.5 hours, then tip it out, rinse, and dry thoroughly.
