Determining whether a washing machine lid switch is broken involves observing specific operational failures during a wash cycle and testing electrical continuity. A primary symptom of a broken lid switch is that the washer fills with water normally, but once the fill stage completes, it refuses to agitate or spin, often pausing indefinitely or flashing an error code. To verify this, unplug the washing machine to ensure safety, remove the top panel to access the lid switch, and attach a digital multimeter set to continuity mode across the switch terminals. Manually depress the switch actuator; if the multimeter fails to register continuity when depressed, or stays open regardless of movement, the switch is broken.
