How to Fix / Troubleshooting
Safety: Unplug the cleaner and remove any detergent cartridges or reservoirs.
- Check detergent level: Ensure the detergent reservoir or cartridge is not empty.
- Flush detergent line: Run a tank of clean water only, activating the spray to flush detergent residue from the lines.
- Clean dosing valve: If accessible, remove the dosing valve and soak it in warm water to dissolve dried detergent. Gently move the valve plunger to free it.
- Solenoid test (advanced): A technician can test the dosing solenoid coil for correct resistance. Replace the valve/solenoid assembly if defective.
