Question:

What should I do if I get a 4E, 4E 1, or 4C error code on my dishwasher's display?

Answer:

Check the water pressure - Ensure that your dishwasher has a minimum of 20 psi and a maximum of 120 psi.

Test the water temperature - The supplied water should not exceed 176�F (80�C).

Inspect the hose - Do not use Floodsafe hoses, as they're incompatible with Samsung dishwashers.

Verify the water supply valve - Make sure it's fully open (turn clockwise to close, counterclockwise to open).

If the problem persists after checking these issues, service will be needed.
