Garbage disposal emits a persistent bad odor even after running with water.

Safety first: Turn OFF the disposal and keep hands clear of the chamber.

• Clean splash guard: Remove the rubber splash guard (if removable on your Franke model) and scrub both sides with hot soapy water and a brush.
• De-grease chamber: Pour a mixture of hot water and dish detergent into the disposer, then run it for 30 seconds with cold water to flush grease.
• Use ice and citrus: Grind a tray of ice cubes with a few lemon or orange peels to help scour the grind ring and freshen the smell.
• Clean discharge elbow: Remove and clean the Franke discharge elbow if odors persist, as sludge can accumulate there.
