Risk level
Low
Usually safe to check without specialist tools.
Urgency
Low
Quick answer
On a Samsung dishwasher, PE means the half load function is not performing correctly. Samsung says to empty the dishwasher, add detergent and run a half load cycle to check it.

- Do not remove the kickplate or panels to look for the half load part: behind them are mains wiring and water connections.

- Do not attempt this professional task: Half load cycle after the repair
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.
Half load system check
What they doThe technician reproduces the half load cycle using Samsung's service documentation and checks the parts that run that function on your model and their connections.
They must show youthe cycle reproduced and the part or connection at fault.
In writingthe cause, the part number replaced and the reason.
Half load cycle after the repair
What they doOnce finished, the technician repeats the half load cycle with the appliance empty and checks PE does not return.
They must show youthe half load cycle completed without a code.
In writingthe cycle tested, 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.
Code and model
- Who:
- you, no tools.
- How:
- photograph the display showing PE and the label with model and serial number.
- Result that matters:
- the exact code and the appliance details for support.
- If it is PE:
- go on to emptying it and the test cycle.
- If it is PC or CE:
- that is a different error; Samsung assigns PC to Zone Wash and CE to panel communication.
- Evidence to keep:
- photo of the display and the label.

Emptying the dishwasher
- Who:
- you.
- How:
- take out all dishes and cutlery before the test, as Samsung asks.
- Result that matters:
- an empty appliance, so the test does not depend on how it was loaded.
- If you can empty it without trouble:
- go on to the half load cycle.
- If the door will not open or there is a lot of water inside:
- do not force anything and contact support.
- Evidence to keep:
- note of how it was loaded when PE appeared.

Half load test cycle
- Who:
- you.
- How:
- add detergent and run a half load cycle with the dishwasher empty. Stay nearby to see whether and when the code returns.
- Result that matters:
- whether the half load function finishes without the error.
- If it finishes without PE:
- it was a one-off; use half load again and watch for it.
- If PE returns:
- the fault persists; contact Samsung support with the photo and when it appeared.
- Evidence to keep:
- time of the test and the point at which PE appeared, if it did.

What it means
Samsung US defines PE on its dishwashers as a half load function error: the appliance detects that the function is not performing correctly. The official routine is to empty it, add detergent and run a half load cycle, then contact Samsung support if the error remains. Samsung does not say which part runs the half load on each model, so PE does not point to a specific fault. This PE is unrelated to the PE on Samsung washing machines, which covers a different system.
