LG Dishwasher: not responding
What is this symptom?
Is your LG dishwasher not responding? This common issue often involves an unresponsive control panel or touchpad. Users may find that the buttons do not react when pressed, and the display remains inactive. Possible causes include a malfunctioning control panel, a faulty control board, or an improperly engaged door latch. Identifying the root cause is crucial for an effective repair.
