Quick answer
Drying temperature-sensor error.
Model compatibility: Samsung can reuse or reformat codes across series and model years, so TC2 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
If a Samsung dishwasher shows **tC2**, the verified Samsung meaning in this research set is **drying temperature-sensor error**. Use the code to narrow the diagnosis, then confirm the exact model because code scope can change by product generation or region.

Signs
Symptoms you may notice
The tC2 display becomes more meaningful if the control can stop or limit operation because a temperature reading is missing or implausible.
One clue that supports the tC2 diagnosis is that heating, cooling, drying, or defrost behavior can become inconsistent.
On affected Samsung dishwasher models, the display can return at a similar stage each time the affected sensor is checked.
While tC2 is active, tC2 appears during the dishwasher function associated with drying temperature-sensor error.
When the tC2 condition is present, 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.
The next non-invasive check is to record when the code appears and whether the appliance had just heated, cooled, or defrosted.
To rule out an accessible cause, confirm vents, doors, filters, and ambient conditions are normal where they affect the sensor reading.
With tC2 recorded, use the exact model manual before assuming the sensor itself is defective.
As an external check for tC2, record the code before resetting.
A safe owner-level check is to check water supply, drain path/filter, door, detergent/suds, and visible leaks only when relevant.
Before requesting service for tC2, if the code returns after the supported owner checks, request model-specific diagnosis.
Important safety warning. When working around a dishwasher that shows tC2, 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
Persistent temperature-sensor codes usually require resistance/connection checks at the sensor, harness, and control—work best done with the model-specific service procedure. If tC2 keeps returning, record the stage at which it reappears so the technician can test the drying temperature-sensor error path instead of replacing parts by guesswork.
Book your repair
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 **tC2** returning afterward means the condition still exists. Note the operating stage instead of cycling power repeatedly.
Do not keep operating the appliance through a hazardous symptom just to see whether **tC2** clears. If there is heat, water, electrical, gas, or food-safety risk, stop and arrange diagnosis.
Treat **tC2** 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 tC2** separate from same-looking codes used by other Samsung appliance families.
