Dishwasher displays E19 and may have issues with the water softener or regeneration cycle.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Defective regeneration valve coil, Blocked brine channel, Wiring fault to softener valve, Control board driver failure

Safety first: Unplug the appliance before removing panels.

Check salt system: Ensure the salt reservoir is filled with dishwasher salt and that no foreign objects are inside the tank.
Inspect regeneration valve: Access the side of the dishwasher to locate the small valve on the softener tank. Check for secure wiring and signs of leakage.
Clean brine channel: If accessible, flush the brine channel with warm water to remove salt deposits.

If E19 persists, the regeneration valve or control board will likely need replacement by a professional.
