# Samsung dishwasher error code HE

### What HE means on this make

Different from the high-temperature code above: here the machine cannot trust the reading rather than seeing one that is too high. The visible symptom is usually dishes that come out cool and wet, because a machine that cannot confirm its water is hot will not run the heated part of the cycle.

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

On the appliance’s own display. Samsung reports errors two ways: machines with a digital display show a code, and the same machines without one blink their cycle lights instead. Both are published by the maker and both are on this site. Photograph what the panel shows before cutting the power — Samsung asks for this itself on its refrigerator and dishwasher pages, and it is the one thing that makes a first visit more useful. A code that has been reset is information a technician no longer has.

### What to do about it

- Empty the machine, add detergent and run a normal cycle.
- Note whether dishes are coming out cool as well as the code appearing — that combination narrows it usefully.
- If it repeats, cut power at the breaker and have the heater and its sensor measured.

### 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.
