Possible Causes
Faulty diverter valve coil, Jammed diverter mechanism, Wiring fault to diverter, Control board output failure
How to Fix / Troubleshooting
Safety first: Unplug the dishwasher before accessing the base or side panels.
- Locate diverter valve: On some De Dietrich models, a diverter valve controls water distribution between spray arms. It is usually mounted on the sump or circulation pump outlet.
- Inspect for blockage: Remove the valve and check for debris preventing movement. Clean thoroughly.
- Test coil: Measure resistance of the diverter coil with a multimeter. Replace the valve if the coil is open or shorted.
- Check wiring: Ensure the harness from the control board to the diverter is intact and connectors are secure.
- Reassemble and test: Run a cycle and listen for the diverter operating. If E19 persists, the control board may need professional evaluation.
