Compatible models

Also shown as

On US and Canadian models, 3C means a pump error but 3E means the incoming water is too hot (see the 3E entry). UK and Australian guides list 3C and 3E together as the pump code. Check your manual.

Difficulty

Try the basic checks, but the usual fix is a technician's job.

Safety first: unplug the dishwasher (or switch off its breaker) before touching filters, hoses or panels. If you smell burning or gas, or see water near the outlet, stop and call a professional.

How to fix Samsung 3C

  1. Power cycle the dishwasher

    Switch the dishwasher off at its circuit breaker (or unplug it) and wait about 1 minute. Restore power and start a fresh cycle. If the code clears and stays away, it was likely a one-time glitch.

  2. Clean the filter

    Switch off the breaker or unplug the dishwasher first. Remove the bottom rack, take out the filter at the bottom of the tub (your manual shows how), and rinse it under running water with a soft brush. Refit it so it locks in place.

When to call a technician

If the code comes back after a restart, request service. The wash pump or its control needs a technician.
