# Samsung dishwasher error code 3C

### What 3C means on this make

The pump that circulates water round the tub is not doing its job. It is one of the more definite codes this machine publishes: there is not much between a pump that runs and one that does not. What is worth eliminating first is whether it is the pump or what is reaching it — a machine that cannot fill also cannot pump.

### Where this appears, and why not to clear it

On the appliance’s own display. Samsung reports errors two ways: machines with a digital display show a code, and the same machines without one blink their cycle lights instead. Both are published by the maker and both are on this site. Photograph what the panel shows before cutting the power — Samsung asks for this itself on its refrigerator and dishwasher pages, and it is the one thing that makes a first visit more useful. A code that has been reset is information a technician no longer has.

### What to do about it

- Switch the dishwasher off, wait, and try a cycle again.
- Listen at the start of the cycle: silence where there should be a circulating hum points at the pump; a labored or grinding noise points at something in it.
- If the code returns, this is a repair rather than a reset.

### Where this goes next

The job this usually becomes is [dishwasher pump replacement](/services/dishwasher-pump-replacement/), and that page carries a starting figure and the reasons that move it. If it turns out to be nothing — and on this make a real share of these are modes, reminders and settings rather than problems — the visit ends there and you pay the diagnostic and nothing else, or call [(305) 506-1256](tel:+13055061256) and describe what the panel is doing before booking anything.
