The dirty water tank is difficult to remove or refit, which may cause poor sealing.

Safety: Unplug the appliance before forcing any parts.

• Clean rails and guides: Remove the dirty water tank and clean the rails and guides on the machine body.
• Inspect latch: Check the tank latch for cracks or deformation. Replace it if it does not hold securely.
• Check tank shape: Look along the edges of the tank for warping from heat. Replace the tank if distorted.
• Re-seat gasket: Ensure the tank gasket is evenly seated and not twisted.
