Washer-dryer displays E19; may be associated with detergent drawer or water distribution issues.

Safety first: Unplug the appliance and close water taps.

• Clean detergent drawer: Pull out the drawer fully and press the release tab to remove. Soak in warm water and scrub away detergent buildup, especially around siphon caps.
• Clean dispenser housing: Use a brush to clean the water jets and channels inside the housing.
• Check water flow: With the drawer removed and machine on a rinse cycle (caution: live voltage), briefly observe water flow into the dispenser. If weak or misdirected, the distribution valve may be faulty.
• Inspect valve (with power off): Access the multi-way valve from the top, check connectors, and test coil resistance. Replace if open circuit or mechanically stuck.

Warning: Work around live water and electricity only if you are competent. Otherwise, limit yourself to cleaning and call a technician for valve diagnostics.
