HC
Samsung HC on a dishwasher: temperature too high while heating
Risk level
Medium
Proceed carefully and stop if the check is unclear.
Urgency
High
Quick answer
On a Samsung dishwasher, HC is a high temperature heater error: the control detects overheating inside the unit. Samsung says to power cycle it and run a normal cycle with detergent. If it happens again, call the service centre.
Safety first

- If you notice a burning smell or warped plastic, cut power at the breaker and do not use the dishwasher again until the service technician inspects it.
Safe checks you can perform
- Restart and normal cycle
- Signs of abnormal heat
- Model and code for the service
Leave these tasks to a qualified professional
- Do not attempt this professional task: Heating circuit diagnosis
- Do not attempt this professional task: Monitored test cycle
What a technician must be able to justify
Technician visit
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Heating circuit diagnosis
What they doWith the unit disconnected, the technician measures the heater, its control and the temperature sensor against Samsung specification.
They must show youthe measured values against specification.
In writingwhat was measured, the result, the replaced part with its reference and the reason.
Monitored test cycle
What they doAfter the repair, the technician runs a normal cycle and checks the temperature stays in range and HC does not return.
They must show youa full cycle with no code.
In writingthe test, the result and the date.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Restart and normal cycle
- Who:
- you.
- How:
- switch the dishwasher off, switch it back on and run a normal cycle with detergent, as Samsung says.
- Result that matters:
- whether the cycle finishes without HC.
- If it finishes with no code:
- it was a one-off glitch; watch the next loads.
- If HC returns:
- Samsung asks you to contact the service centre; do not keep repeating cycles.
- Evidence to keep:
- note the date, the programme and when HC appeared.

Signs of abnormal heat
- Who:
- you, without opening the unit.
- How:
- after a cycle with HC, check from outside for a burning smell, unusual steam or warped plastic parts in the tub.
- Result that matters:
- knowing whether to stop using it now.
- If you notice a burning smell or warped plastic:
- cut power at the breaker and do not use it until inspected.
- If nothing looks abnormal:
- wait for the inspection without repeating cycles.
- Evidence to keep:
- a photo of any warped part and a note of the smell.

Model and code for the service
- Who:
- you.
- How:
- photograph the panel showing HC and the model and serial label; note whether your model has rotary spray arms.
- Result that matters:
- the service knows which heating system it has.
- If it is under warranty:
- say so when you request service.
- If your model shows 1E or IE instead of HC:
- Samsung uses those on rotary models for the same error, tell the technician.
- Evidence to keep:
- dated photos.

What it means
Samsung defines HC as a high temperature heater error and Samsung Canada describes it as overheating inside the dishwasher; on rotary spray arm models it also uses 1E or IE for the same thing. Samsung Latin America groups HC with HE as a high temperature heating check. The home step it gives is to restart the unit and run a normal cycle with detergent. The code does not name which part causes the excess temperature: if it repeats, the service technician diagnoses it.
