Possible Causes
Stuck ceramic valve due to scale, Broken valve motor or gear, Faulty valve position sensor, Loose valve connector
How to Fix / Troubleshooting
Safety: Unplug the machine and allow it to cool.
- Descale: Run a complete descaling cycle to reduce scale in the valve and hydraulic block.
- Access valve: Remove the side panel to locate the ceramic diverter valve (often a round plastic housing with a small motor).
- Inspect movement: With the machine unplugged, gently attempt to rotate the valve shaft (if accessible). Do not force it; if seized, replace the valve assembly.
- Check motor and sensor: Verify the valve motor connector is secure. Test the motor and position sensor continuity with a multimeter and replace the valve if defective.
