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

Power cycle for a minute
Switch the dishwasher off at the breaker (or unplug it) for about 1 minute, then turn it back on and try a fresh cycle.
Clean the filter
With the power off, lift out the bottom rack, remove the filter from the tub floor and rinse it under the tap with a soft brush. A clogged filter can starve the pump. Lock it back in place before running a cycle.

When to call a technician

A 3C that returns after a restart needs a technician to look at the wash pump or its control.
