Washer-dryer combo stops mid-cycle with water in the drum and shows 5C on the display.

Safety first: Disconnect power and prepare for water spillage.

Steps to troubleshoot:

• Clean filter thoroughly: Open the lower access panel, drain residual water, and remove the pump filter. Use a flashlight to inspect deeper into the pump housing for socks, hair ties, or other small items.
• Check sump hose: If comfortable removing panels, access the large black rubber hose between the tub and pump (sump hose). Clamp it, remove the spring clamps, and inspect for blockages. Clean and reinstall securely.
• Inspect wiring: With the front or bottom panel removed (depending on model), verify the electrical connector to the drain pump is firmly seated and wires are not damaged.
• Test cycle: Reassemble and run a rinse & spin cycle to confirm the error is cleared.

When to stop: If the pump is silent (no humming) during drain, the pump motor or main PCB may be defective. Replacement of the pump is usually straightforward but involves working under the machine; consider a technician if space is limited.
