Dishwasher interior light (if fitted) does not work, but the machine otherwise operates normally.

Safety first: Unplug the dishwasher before accessing the light assembly.

• Locate light: The interior light is usually mounted on the side or top of the tub.
• Inspect lens and housing: Remove the cover and check for water ingress or corrosion.
• Replace lamp/module: Fit a CDA-compatible lamp or LED module if the original has failed.
• Check wiring: Ensure connectors are secure and not corroded.
