Washer-dryer combo makes a clicking or rattling noise from the pump area even when not draining.

Safety first: Unplug the unit before opening the pump filter.

• Clean pump filter: Open the lower access panel, drain residual water, and remove the filter. Remove any coins, buttons, or debris.
• Check impeller: Spin the impeller gently to ensure it is secure and not wobbling excessively.

Some intermittent pump noise is normal during certain cycles, but persistent loud rattling after cleaning may require pump replacement.
