Washer-dryer leaves detergent or softener in the drawer at the end of the cycle.

Safety first: Unplug the appliance and turn off the water supply before removing the top cover if needed.

Step-by-step checks:

• 1. Clean drawer and housing: Remove the detergent drawer and wash thoroughly. Clean the housing and siphon caps.
• 2. Check water jets: With the drawer removed, briefly start a fill (carefully, with no contact with live parts) to see if water flows from the jets. If weak or uneven, unplug and clean the jet holes with a brush or descaling solution.
• 3. Water pressure: Ensure the inlet tap is fully open and household water pressure is adequate.
• 4. Drawer fit: Reinsert the drawer fully. A partially open drawer can prevent proper flushing.
