Samsung Dishwasher code **1C** is associated with **low-water-level / water-level detection error**. The display identifies the system or condition the control detected, but it does not by itself prove which individual part should be replaced. Samsung uses overlapping code conventions across model years and regions. This page keeps the appliance context attached to the code so a same-looking string from another product family is not misapplied. The recorded display form is **1C**. Search normalization stores it as **1C** while preserving the characters a homeowner actually sees.

Quick answer
Low-water-level / water-level detection error.
Model compatibility: Samsung can reuse or reformat codes across series and model years, so 1C 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
Samsung Dishwasher code **1C** is associated with **low-water-level / water-level detection error**. The display identifies the system or condition the control detected, but it does not by itself prove which individual part should be replaced. Samsung uses overlapping code conventions across model years and regions. This page keeps the appliance context attached to the code so a same-looking string from another product family is not misapplied. The recorded display form is **1C**. Search normalization stores it as **1C** while preserving the characters a homeowner actually sees.
Signs
Symptoms you may notice
On affected Samsung dishwasher models, the appliance may receive too little water or fail to confirm the expected water level.
On affected Samsung dishwasher models, the code often appears near the beginning of a fill stage.
One clue that supports the 1C diagnosis is that water may enter slowly, intermittently, or not at all.
Depending on the exact model, 1C appears during the dishwasher function associated with low-water-level / water-level detection error.
A symptom that fits 1C is that the cycle can stop, drain, fail to fill/heat, or repeat a stage.
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
With 1C recorded, confirm the household water supply valve is fully open where the appliance uses one.
With 1C recorded, inspect accessible supply hoses for kinks and clean inlet screens only as described by Samsung.
To rule out an accessible cause, verify whether water actually enters before the code appears.
Before opening any service area, verify hot/cold hose routing and water pressure when relevant to the exact appliance.
Before requesting service for 1C, record the code before resetting.
To rule out an accessible cause, verify water supply, drain path/filter, door, detergent/suds, and visible leaks only when relevant.
Important safety warning. Stop use for active leakage near electrical parts, burning smell, or repeated breaker trips. Do not defeat leak or door-safety switches. Do not bypass a safety device merely to see whether 1C disappears.

When to request repair service
If supply flow is proven good and the display returns, inlet valves, flow/level sensing, wiring, or control electronics may require diagnosis. A repeatable 1C event is more useful diagnostically than repeated resets, because it shows when the low-water-level / water-level detection error check is failing.

Book a specialist visit for a clear estimate and approval before any repair.
Resetting can clear a temporary state, not a persistent issue. If **1C** comes back, preserve the code and move to the safe checks or model-specific service path.
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.
Treat **1C** 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 1C** separate from same-looking codes used by other Samsung appliance families.
