Washer's drum light (if equipped) does not turn on, but machine otherwise works.

Safety first: Unplug the washer before accessing the drum light.

• Check settings: Some models allow disabling the drum light in settings; verify it is enabled.
• Inspect light module: Access the drum light from inside the drum or via the front panel and check for visible damage.
• Replace module: If the light module is non-functional and receives power, replace it with a compatible part.
• Door switch: If the light is triggered by door opening, ensure the door switch is working correctly.
