Means: Door is properly closed
Next: If the latch is stuck, use a rubber mallet to gently tap it into place.
Reset the Dishwasher
Do: Unplug the dishwasher for 1 minute, then plug it back in.
Observe: Dishwasher resets and responds to control panel inputs
Means: Reset resolved a minor electrical issue
Next: If the dishwasher still doesn't start, proceed to test the door switch.
Test Door Switch
Do: Use a multimeter to check for continuity in the door switch when the door is closed.
Observe: Multimeter shows continuity
Means: Door switch is functioning
Next: If no continuity, the door switch may need replacement.
Check Control Panel
Do: Look for error codes or unresponsive buttons on the control panel.
