Quick Answer: Resetting a LG Dishwasher#
An LG dishwasher board glitch will not clear from the touch panel, so reset it at the breaker or the under-sink switch for a minute. Restoring power reboots the control board cleanly and recovers a locked or unresponsive display. It cannot repair a blocked drain or an inlet valve that has failed.
How to Reset a LG Dishwasher (Step by Step)#
- Cut power to the LG dishwasher at the breaker or under-sink switch; an LG board glitch will not clear from the touch panel alone.
- Leave it off for one minute, then restore power so the LG control board reboots cleanly.
- If the panel shows a control lock, hold the two buttons printed with the small lock icon together for three seconds until the lock indicator clears.
- Once it runs, use Smart Diagnosis through the LG ThinQ app to read any fault that survived the reset before you call it fixed.

LG Dishwasher Model Variations#
QuadWash and TrueSteam models reset the same way, since the steam feature does not alter the sequence. Top-control units hide the lock buttons on the top door edge, while front-control ones show them on the fascia. Most recent LG dishwashers support Smart Diagnosis through the ThinQ app, whereas older units rely on the power-cycle alone.
When a Reset Doesn't Fix Your LG Dishwasher#
If a code reappears in Smart Diagnosis after the reboot, decode it on our LG error-code guide rather than resetting again. When water is the complaint, follow the dishwasher-not-draining, will-not-start, and control-lock symptom pages. A fault that survives a clean power-cycle usually points to the drain pump, the inlet valve, or a sensor, not the board.
Safety First — Know the Risks
Live 120V wiring in a wet environment is one of the most dangerous DIY scenarios. Water + electricity = serious shock risk. Our techs are licensed and insured — let them handle the risk.

LG Dishwasher Reset FAQ#
How do I reset an LG dishwasher?
Switch the dishwasher off at the breaker or under-sink switch, leave it dark for a minute, then restore power so the control board reboots. The touch panel alone will not clear a board glitch.
What does the control lock mean on an LG dishwasher?
Control lock freezes the buttons so a cycle cannot be changed or started by accident, shown by a small lock icon. Hold the two buttons printed with the lock symbol together for about three seconds to clear it.
How does LG Smart Diagnosis work on a dishwasher?
Smart Diagnosis lets the machine report its stored fault to the LG ThinQ app or a support line, so you can read a code without opening anything. Use it after a reset to see whether a fault actually survived.
How do I turn off the control lock on an LG dishwasher?
Press and hold the pair of buttons marked with the small lock icon together until the lock indicator disappears. On top-control models those buttons sit on the top edge of the door.
Why will my LG dishwasher not drain?
Water left in the tub usually means a clogged filter or drain hose, not a board fault. Clean the filter at the base and check the hose at the disposer before testing the pump.
