DishDrawer or dishwasher displays F13; unit may not start or may stop with error.

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

Blocked softener valve, Low or incorrect salt, Faulty softener control valve, Softener sensor failure

Safety first: Disconnect power and turn off water before servicing.

Check salt level: Open the salt reservoir cap and ensure it is filled with the correct dishwasher salt (not table salt). Top up if low.
Clean around cap: Wipe away any salt residue around the cap and ensure it seals properly.
Run a regeneration cycle: If your model allows, manually start a softener regeneration cycle as per the user manual.

If F13 persists, the softener valve or softener sensor may be faulty and require replacement.
