Washer-dryer combo does not drain; water remains in drum and E2 is displayed

Safety first: Unplug the Roborock washer-dryer combo. Water may spill when opening the filter—have towels and a shallow tray ready.

• Access the drain filter: Open the lower service flap on the front of the unit. Place a tray under the filter cap.
• Drain residual water: If equipped with an emergency drain tube, pull it out and drain into the tray. Then slowly unscrew the filter cap to release remaining water.
• Clean the filter: Remove lint, coins, hairpins, and other debris from the Roborock drain filter and housing. Spin the pump impeller with your finger to ensure it moves freely.
• Check the drain hose: Inspect the rear drain hose for kinks or clogs. Detach from the standpipe and flush with water if necessary.
• Test operation: Reinstall the filter, close the flap, reconnect power, and run a drain/spin cycle. If E2 persists and you hear no pump noise, the Roborock drain pump motor is likely faulty and should be replaced.
