For the Samsung Dishwasher families covered by the source set, **0C** means **over-level / too much water error**. The first useful step is to preserve the exact characters and model number before power cycling the appliance. Samsung appliances monitor whether a function reaches an expected state within a certain sequence. When that check fails, the control can store or display a code even though the root cause may sit elsewhere in the same circuit. The recorded display form is **0C**. Search normalization stores it as **0C** while preserving the characters a homeowner actually sees.

Quick answer
Over-level / too much water error.
Model compatibility: Samsung can reuse or reformat codes across series and model years, so 0C may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
For the Samsung Dishwasher families covered by the source set, **0C** means **over-level / too much water error**. The first useful step is to preserve the exact characters and model number before power cycling the appliance. Samsung appliances monitor whether a function reaches an expected state within a certain sequence. When that check fails, the control can store or display a code even though the root cause may sit elsewhere in the same circuit. The recorded display form is **0C**. Search normalization stores it as **0C** while preserving the characters a homeowner actually sees.
Signs
Symptoms you may notice
When the 0C condition is present, the appliance may stop or limit the affected function when the code is detected.
One clue that supports the 0C diagnosis is that the same code may return at a repeatable stage of operation.
A symptom that fits 0C is that other symptoms depend on the model and the subsystem named by Samsung.
When the 0C condition is present, 0C appears during the dishwasher function associated with over-level / too much water error.
A symptom that fits 0C is that 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.
A safe owner-level check is to record the exact code, model number, and operating stage before resetting power.
To rule out an accessible cause, complete only the owner-accessible checks described in the model manual.
Before requesting service for 0C, do not replace parts solely from a display code when wiring, conditions, or control feedback can create the same result.
A safe owner-level check is to record the code before resetting.
Before requesting service for 0C, verify water supply, drain path/filter, door, detergent/suds, and visible leaks only when relevant.
As an external check for 0C, if the code returns after the supported owner checks, request model-specific diagnosis.
Important safety warning. When working around a dishwasher that shows 0C, 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 code returns after the documented basic checks, request model-specific diagnosis of the affected subsystem. A repeatable 0C event is more useful diagnostically than repeated resets, because it shows when the over-level / too much water error check is failing.

Seeing this code on your Samsung appliance?
Book a specialist visit for a clear estimate and approval before any repair.
You can try the one reset Samsung documents for the model, but **0C** returning afterward means the condition still exists. Note the operating stage instead of cycling power repeatedly.
That depends on the accompanying symptom. A code with no safety hazard may allow a short diagnostic check, but **0C** should not be ignored if performance is deteriorating or the display keeps returning.
Treat **0C** as a starting point, not a replacement instruction. Wiring, feedback signals, operating conditions, and electronic controls can mimic a failed component.
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 0C** separate from same-looking codes used by other Samsung appliance families.
