Applies to

Samsung Dishwasher; United States. This page is not a brand-wide diagnosis.

The dishwasher may stop, fail to fill, or show 4C or 4E early in a cycle.

Confirm the code is 4C or 4E.
Check the household water supply valve if it is accessible.
Look for obvious inlet hose kinks or shutoff without moving the built-in appliance unsafely.

Stop if water leaks, supply access is unsafe, or the code returns after accessible checks.

Record model code, water supply state, installation details, and exact displayed code.
