Seeing **5C** on a Samsung dishwasher narrows the problem to **drainage error**. What you do next depends on whether the code is an issue, a normal status/test message, or a model-dependent interpretation. A display code is evidence from the control system, not a component test result. That distinction matters because a connector, supply condition, obstruction, or feedback signal can mimic a failed component. The recorded display form is **5C**. Search normalization stores it as **5C** while preserving the characters a homeowner actually sees.

Quick answer
Drainage error.
Model compatibility: Samsung can reuse or reformat codes across series and model years, so 5C may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

What this code means
Seeing **5C** on a Samsung dishwasher narrows the problem to **drainage error**. What you do next depends on whether the code is an issue, a normal status/test message, or a model-dependent interpretation.

Signs
Symptoms you may notice
While 5C is active, water or condensate can remain where the appliance expects it to be removed.
Depending on the exact model, a cycle can pause, extend, or stop during the drain stage.
While 5C is active, a pump may run longer than normal or sound different while the code is active.
One clue that supports the 5C diagnosis is that 5C appears during the dishwasher function associated with drainage error.
The 5C display becomes more meaningful if the cycle can stop, drain, fail to fill/heat, or repeat a stage.

Before you call
Safe checks you can make
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
As an external check for 5C, check and clean only the user-accessible filter or drain area described in the model manual.
Before opening any service area, verify the external drain hose for kinks, freezing, crushing, or an incorrect installation height.
As an external check for 5C, verify the household standpipe, sink, disposal connection, or condensate path is not restricted.
To rule out an accessible cause, record whether the pump runs and whether fluid actually leaves the appliance.
The next non-invasive check is to record the code before resetting.
For 5C, start by doing this: check water supply, drain path/filter, door, detergent/suds, and visible leaks only when relevant.
Important safety warning. When working around a dishwasher that shows 5C, keep the checks external and non-invasive. Stop use for active leakage near electrical parts, burning smell, or repeated breaker trips. Do not defeat leak or door-safety switches.

When to request repair service
If the owner-accessible checks do not clear 5C, If the accessible drain path is clear but the code returns, the pump, internal hose, water-level sensing, wiring, or control may need model-specific testing. The repair should confirm the monitored function and its feedback before any board or component is condemned.

Book a specialist visit for a clear estimate and approval before any repair.
One controlled restart is reasonable after correcting an obvious external issue. A recurring **5C** display should be treated as diagnostic evidence, not as a reason to keep rebooting the appliance.
Continue only if the appliance is otherwise safe and the owner-level checks are appropriate. Stop for leakage near electrical parts, smoke, burning odor, arcing, gas concerns, repeated breaker trips, uncontrolled heating, or unsafe temperatures.
The code alone is not enough to justify a part. **5C** should narrow testing to the affected function; the final cause still has to be verified on the exact model.
The same-looking code can be reused on another Samsung appliance family or reformatted by region/model year. Match the appliance type and exact model before applying a meaning. This page therefore keeps **Dishwasher 5C** separate from same-looking codes used by other Samsung appliance families.
