LG Dishwasher CR Code — Test Mode Active
What this means
The CR code indicates the dishwasher has entered Test Mode, a diagnostic mode used by installers and service technicians to check the functionality of various components. This is not an error but a service state that was accidentally activated. CR is triggered by pressing and holding a specific combination of 3 buttons simultaneously.
Step-by-step fix
2 stepsExit test mode
Turn off the dishwasher and wait 1-2 minutes, then turn it back on. This should bring the unit out of test mode.
Power-cycle if needed
If the CR code persists after turning off and on, unplug the dishwasher or turn off the circuit breaker for 1 minute, then restore power.
When to call a professional
If the dishwasher will not exit test mode after power-cycling, a technician may need to reset the control board.
