How to Fix / Troubleshooting
Safety first: Unplug the washer and close water taps before removing the dispenser or valves.
- Clean dispenser drawer: Remove the detergent drawer and wash thoroughly under warm water, clearing all compartments and siphon caps.
- Inspect dispenser housing: Check the housing for mold, hardened detergent, or obstructions in the water jets. Clean with a soft brush.
- Check dispenser valve: Access the dedicated dispenser valve (if separate from main inlet). Test coil resistance and inspect wiring.
- Automatic dosing (if fitted): For Primus models with liquid dosing pumps, inspect the pump tubes for blockages and ensure the pump runs when commanded. Replace blocked or failed pumps.
- Test wash: Reassemble and run a cycle, observing whether water flows correctly through the dispenser and E19 is cleared.
