Possible Causes

Defective internal diverter valve (wash/dry circuit), Blocked internal recirculation path, Wiring fault to diverter valve, Control board valve driver failure

How to Fix / Troubleshooting

Safety first: Unplug the appliance and close the water tap.

Step-by-step checks:

  • 1. Listen for valve operation: During program transitions (wash to dry), you may hear a click from the diverter valve. Absence of sound may indicate a failed valve.
  • 2. Access diverter valve: Remove the top or rear panel to locate the internal valve assembly connected to hoses between tub, condenser, and pump.
  • 3. Test coil resistance: Disconnect the valve connector and measure coil resistance. An open circuit indicates a failed valve that must be replaced.
  • 4. Check for blockages: Inspect connected hoses for kinks or blockages that may prevent proper water routing.

When to call a technician: If the valve and hoses are fine but E19 persists, a control board fault is likely and should be handled by a professional.
