Samsung Washer Error Code 4E2

The 4E2 code means the washer has detected incoming water with a temperature above 50 degrees Celsius during a dry cycle or while running a Wool or Lingerie wash course. These cycles require cool water to protect delicate fabrics, so the machine stops to prevent potential damage. The most common reason is that the hot and cold inlet hoses are connected in reverse at the back of the unit.

You should not continue running the affected cycle until the issue is resolved. Hot water entering during a Wool or Lingerie cycle can shrink or damage delicate fabrics. The washer stops automatically as a protective measure, and resolving the root cause before restarting is the right approach.

If the problem is simply reversed inlet hoses, there is no parts cost and the fix takes only a few minutes. If a plumbing issue is involved, plumber costs will vary by location and complexity. Replacing a faulty water temperature sensor or thermistor typically involves a parts cost in the range of 15 to 50 dollars plus labor if a technician is needed, which can add 80 to 200 dollars depending on your area.

Start by turning off the water supply and inspecting the inlet hoses at the back of the washer to confirm the cold hose is connected to the cold water tap and vice versa. If the connections are correct, run the cold tap near the machine and test the water temperature to rule out a plumbing cross-connection or an overly hot water heater. If water supply temperatures are normal and connections are correct, a technician should test the water temperature sensor for proper operation.

Resetting the washer, typically by unplugging it for a few minutes and restarting, may temporarily clear the error display. However, if the underlying cause is not corrected, such as reversed hoses or a faulty temperature sensor, the code will return as soon as the affected cycle runs again. A reset alone is not a fix.
