Samsung’s drain guidance covers standing water with or without a code, including 5C and 5E. Start with the shared sink drain, recent installation changes and the accessible hose route. Do not substitute a washing-machine 5C procedure for dishwasher instructions.
Brand-level navigation and symptom classification. Exact-model pages own their documented controls and access procedures.
Stop and isolate power before permitted user maintenance, and let water cool. Watch for sharp debris. Do not reach blindly into a sump, open electrical panels or use drain-opening chemicals. Stay clear of water near electrical equipment.
Choose the observed outcome
The timing around disposal replacement is an important branch, not a universal explanation for every Samsung drain fault. A dishwasher that never drained after installation and one that stopped after months of normal operation need different histories. A code helps identify the symptom, but accessible plumbing checks and the exact model manual still determine what an owner may safely inspect.
Start with the relevant branch
Check the sink-side context
A clogged sink or disposal can affect the shared drain route. Do not put a hand into a disposal; use its own safety instructions or obtain plumbing help.
Consider installation changes
If a disposal or dishwasher was just installed, ask the installer to check the connection and any required knockout removal. Do not disconnect hoses from a powered appliance.

When to stop and get help
Only carry out maintenance permitted in your model’s manual. For service, note the full model number and suffix, displayed code, selected cycle and what happened during the checks. Leave internal wiring, gas components, pumps and safety devices to a qualified professional. A symptom alone does not identify a failed part.
