Use this guide to pull stored error codes and run built-in tests on a Samsung front-load washer with the WF42H* style control panel. These diagnostics can help you narrow problems down to the door lock, drain pump, water valves, wiring, or the control board before you start replacing parts.

ШагиSteps

Prepare the washer for diagnostics

Confirm the washer is plugged in, and the control panel matches the WF42H* style layout shown in the video.
Leave the washer powered off at the console when you plan to enter quick test mode.
Turn the washer on at the console when you plan to enter the service mode used to read error codes.

Enter service mode for error code diagnostics

Power on the washer.
Press and hold the Delay Start button and a Soil Level button at the same time.
Release the buttons after you hear a chime and the display shows all zeros.

Display and scroll through stored error codes

Press the Soil Level button once to start the error code display.
Confirm the letter "D" appears on the screen to show the washer is in the error code diagnostic process.
Turn the jog dial either direction to cycle through stored codes.
Keep scrolling until the display returns to the letter "D" to confirm all stored codes have been shown.
Press the Spin button to exit the error code mode and return to the broader service mode.

Check the software version and cycle information

Press the Soil Level button to display the washer's software version.
Use the cycle count function to show how many times the washer has been run since it was purchased.
Press Start while in error code mode to display how many cycles have run since the displayed error code occurred.
Press the Power button to power down and exit service mode.

Run the spin test mode

Press and hold the Delay Start button and the Temperature button until the door locks and the washer begins to spin.
Watch the digital display as a tachometer that shows drum speed in rpm.
Expect heavy shaking between 300 and 400 rpm until the counterweights align, and the spin smooths out.
Treat continued severe shaking as a sign of a major issue such as shocks, springs, the spider bracket, or another component.
Cancel the spin test by pressing the Temperature button and the Delay Start button at the same time.
Wait for rpm to drop to zero before trying to open the door.

Enter quick test mode

Confirm the washer is off at the console and the display is dark.
Press and hold the Spin button, the Soil Level button, and the Power button together for about five seconds.
Release the buttons after quick test mode activates.

Use quick test mode features

Use the door lock test to check whether the door lock mechanism responds.
Use the drain pump test to check whether the drain pump runs.
Use the water valve test after locking the door by pressing the Spin button.
Run the memory clear test by pressing and holding the Delay End button and the Power button together.
Press the Power button to exit quick test mode.

Use safe troubleshooting checks tied to many error codes

Unplug the washer before checking for loose or damaged wires.
Check wiring and connectors related to the failing system, such as the drain pump, door lock, or water valves.
Use a multimeter to test the involved component for continuity or resistance (ohms) as needed.
Check for voltage from the control board to the component, because a board that doesn't send voltage may be at fault.

Investigate unbalanced shaking related to a DC error

Check the basket for warping and extreme wear if the washer shows a DC unbalanced error.
Treat severe wear and shaking as a possible sign the spider bracket has snapped in the back of the basket.

Fix an unresponsive diagnostic mode connection

Repeat the diagnostic mode entry procedure two or three times if the washer doesn't respond to commands.
Turn the washer off, turn it back on, and try entering the mode again if the error code scroll feature doesn't work.
Don't unplug the washer for this issue, because the video reports power cycling at the console was enough.
Expect touch-style controls to sometimes require multiple tries before service mode becomes responsive.

Understand limitations of the provided source for specific code meanings

The source video references common codes such as 1E, 3E, E3, NF, ND, AE, DS, DL, LO, HR, and OE, but it does not walk through each one individually.

Exit diagnostics after testing and confirm the washer returns to normal standby before further troubleshooting. Repair didn't go as planned? Ask our Answers community for help.
