# Samsung dishwasher: Thermistor not operating correctly

### What the appliance is actually reporting

A sensor that is not shorted and is not to be trusted either. The practical effect is the same as any temperature sensing problem on a dishwasher: the heated parts of the cycle stop being reliable, and drying goes first.

### Where this appears, and why not to clear it

On the cycle lights, on a machine with no digital display. Samsung publishes what each combination means, and on those models the combination is the entire diagnosis — it disappears the moment the power is cut. Write it down or photograph the panel before switching anything off. Samsung adds one caution of its own and it saves service calls: on some models the lights blink to show cycle status, so treat it as an error only if the machine is misbehaving as well.

### Which machines this one applies to

Models with no digital display, which report by blinking their cycle lights. Samsung itself flags that several of its codes mean two different things depending on the model — *dC*, *3E* and *BE2* on washers, and *1E* on dishwashers — so the model number is what settles which reading applies to your machine. It also publishes nothing at all for freezers, ice makers and range hoods, which is why those appliances have symptom pages here and no code pages.

### What to do about it

- Empty the machine, add detergent and run a normal cycle.
- Note whether drying has got worse.
- If it repeats, the sensor needs measuring.

### Where this goes next

The job this usually becomes is [temperature sensor replacement](/services/temperature-sensor-replacement/), and that page carries a starting figure and the reasons that move it. If it turns out to be nothing — and on this make a real share of these are modes, reminders and settings rather than problems — the visit ends there and you pay the diagnostic and nothing else, or call [(305) 506-1256](tel:+13055061256) and describe what the panel is doing before booking anything.
