4C2
Samsung 4C2 on a washer: hot water at the cold inlet
Risk level
Low
Usually safe to check without specialist tools.
Urgency
Low
Quick answer
On a Samsung washer, 4C2 (also 4E2, CE or 14C2) means water entering through the cold inlet is very hot. Check the hose is connected to the cold water tap, usually the blue one.
Safety first
Stop and check this first
- Turn the taps off before undoing the hoses: if the supply water comes out very hot, it can scald.
Safe checks you can perform
- Exact code
- Which tap feeds the washer
- Two inlets: blue to blue and red to red
Leave these tasks to a qualified professional
- Do not attempt this professional task: Temperature measurement check
- Do not attempt this professional task: Test wash after the work
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.
Temperature measurement check
What they doOnly if the connections are right and the code returns, the technician checks the water temperature sensor and its connection with a multimeter against Samsung's specification.
They must show youthe water connections checked and the sensor value against the specification.
In writingwhat was measured and, if a part is replaced, its part number and the reason.
Test wash after the work
What they doTo finish, the technician runs a cold wash and checks neither 4C2 nor its variants appear.
They must show youthe wash completed without a 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.
Exact code
- Who:
- you, no tools.
- How:
- photograph the display and note whether it reads 4C2, 4E2, 4E1, 4Ed, 14C2 or CE.
- Result that matters:
- confirming it is the inlet water temperature warning.
- If it is one of those variants:
- check the water connections.
- If it reads 4C or 4E with no number after it:
- that is a different water supply warning; see its page.
- Evidence to keep:
- photo of the display.

Which tap feeds the washer
- Who:
- you.
- How:
- follow the inlet hose from the washer to the tap and see whether it is the cold tap, usually blue, or the hot one, usually red.
- Result that matters:
- knowing whether the washer gets cold water as Samsung requires.
- If it goes to the hot tap:
- turn both taps off, move it to the cold tap and turn it back on.
- If it already goes to the cold tap:
- if your model has two inlets, check for crossing in the next step.
- Evidence to keep:
- photo of the tap and the connected hose.
Evidence: What do the codes on my washing machine mean?
Two inlets: blue to blue and red to red
- Who:
- you, only if your washer has two water inlets.
- How:
- with the taps off, check the hose from the cold tap goes to the cold inlet and the hot one to the hot inlet, blue to blue and red to red, as Samsung US says.
- Result that matters:
- ruling out crossed hoses.
- If they were crossed:
- that was the cause; set them right, open the taps and try a wash.
- If they were correct and the warning remains after a wash:
- contact Samsung support.
- Evidence to keep:
- photo of the rear inlets with their hoses.

What it means
Samsung US groups 4C2, 4E2, CE, 14C2 and nF1 as a hot/cold error: water from the cold supply is extremely hot, which happens when the supply hoses are swapped. It adds that this code does not indicate service is needed. Samsung UK describes it as a water temperature issue (4C2, 4E1, 4E2, 4Ed) and asks you to check the hose is on the cold supply, the blue tap. If the connection is right and the warning returns, it points to how the washer measures water temperature.
