Washing machine screen is blinking and won't turn on

Check the power button and the power cable socket - screen flickering often happens because of poor contact. If that doesn't help, try unplugging the machine from the outlet for 10-15 minutes (to reset the error), then turn it back on. If the screen keeps flickering and the machine doesn't respond to buttons, it's most likely a problem with the electronic control module, and that needs professional diagnosis - I wouldn't risk fixing something like that myself, it's more complicated than it seems.

A flickering screen with no power often indicates a control board issue - it's receiving a signal but can't initialize properly. If the machine doesn't respond to button presses at all, it could be anything from a loose outlet contact to a faulty module itself.

First, try the simplest thing: completely power down the machine for about 20 minutes and turn it back on. A reboot often helps 😊 If that doesn't work, check the outlet itself - plug something else into it (like a lamp) to make sure there's power. Look the cable over for any visible damage and check that it's plugged in securely both at the outlet and in the machine.

If the reboot didn't help, the control board probably needs diagnostics. In that case, it's best to call a technician - don't try to get into it yourself, or you might make things worse.

In my experience, a simple thing often helps - check if the hatch door is closed tightly. On washing machines, the door closure sensor not only regulates the cycle start but also controls power supply to the control board. If the sensor contacts have oxidized or the door doesn't close properly due to wear on the seal, the display can flicker and stop responding to commands. Try opening and closing the door several times firmly, and listen for the latch to click.

If that doesn't work, then it makes sense to mess with the electrics. I agree with the previous advice about resetting - unplug the machine for about 20 minutes and plug it back in, sometimes that helps. Also check the visible parts of the connectors on the back panel for any oxidation or dirt. But if after all that the display is still flickering and the buttons aren't responding at all, then yeah, it's probably an electronics-level issue, and you'll need a technician - the control board might need replacing or reprogramming.
