Possible Causes

Defective diverter or regeneration valve, Jammed valve mechanism, Wiring fault, Control board driver issue

Safety first: Unplug the appliance.

Clean spray arms and filters: Ensure no blockage is causing abnormal pressure that could affect the diverter.
Access valve: Depending on model, the E19-related valve may be on the side water softener/regeneration unit or attached to the circulation pump. Inspect for scale or debris.
Check connectors: Verify that the valve's electrical connector is secure.
Replace valve: If the valve coil is open-circuit or the mechanism is stuck, replace the valve assembly.
