6C1 — Samsung Dishwasher 6C / 6C1 — Clogged Fine Filter / Water Not Passing
6C (also shown as 6C1) indicates water is not passing through the fine filter properly — typically a clogged or blocked filter restricting circulation. Clean the fine/mesh filter at the bottom of the tub. It is not a detergent-dispenser fault.
