The LOC code on Frigidaire Professional Dishwasher units indicates the child lock panels remain engaged. Disable the feature by pressing and holding the Lock button until the display clears.
Owners often resolve persistent codes through a full power reset after the initial unlock attempt. This approach restores normal cycle selection without external service intervention.
Disable Frigidaire Professional Child Lock
Frigidaire Professional Dishwasher models activate the LOC code when the child lock engages during operation or after a power fluctuation. The lock prevents unintended button presses but can block cycle changes when needed. Users clear the code through direct control panel interaction rather than menu navigation.
The process requires consistent button pressure and timing to register the command. Multiple attempts may occur if the unit senses ongoing input. Power interruption follows if the display stays locked after the hold sequence.
Press and hold the Lock Button for three seconds.
Release once the LOC indicator disappears from the panel.
Select a wash cycle to confirm panel response.
Frigidaire Professional Dishwasher Control Codes Table
Frigidaire Professional dishwashers display control codes to indicate specific operational states or issues. The LOC code specifically relates to the child lock feature that disables the control panels. Users can refer to the following table for a complete list of these codes and their resolutions.
Frigidaire Professional Dishwasher units track several control codes that appear alongside LOC. The table below aggregates common codes with their triggers and standard resolutions based on service patterns.
| Code | Trigger Condition | Resolution Path | Difficulty |
|---|---|---|---|
| LOC | Child lock active | Hold Lock Button | 1 |
| PF | Power failure detected | Reset via breaker | 2 |
| ER | Sensor communication loss | Inspect harness connections | 3 |
| CL | Door latch fault | Replace latch assembly | 4 |
Review the table entries before attempting fixes to match the displayed code accurately. Cross reference the symptom with the listed resolution to avoid unnecessary part replacement.
Frigidaire Professional LOC Surge and Humidity Triggers
Power surges represent the leading cause of repeated LOC codes on Frigidaire Professional Dishwasher models. Control boards interpret brief interruptions as lock commands and retain the state until manually cleared. Environmental factors such as high humidity near the panel can also contribute to false triggers.
Owners should examine the outlet voltage and grounding before repeated resets. Consistent code recurrence after proper unlock points to a board level issue rather than user error. Replacement of the main control board resolves these cases when basic steps fail.
Frigidaire Professional LOC Code Workspace Prep
Prepare the workspace by ensuring the dishwasher sits on a level surface with clear access to the control panel. Locate the circuit breaker for the appliance before starting the unlock process. Have a towel ready to manage any residual water if a cycle was interrupted.
Execute the reset during off peak hours to avoid conflicts with household power loads. Document the exact sequence of button presses used in case the code returns within the same day. Store the user manual nearby for reference on model specific button layouts.
Frigidaire Professional LOC Vibration Causes
Frigidaire Professional Dishwasher units display ongoing LOC codes after door slams or heavy vibration during cycles. These events can shift internal connections enough to mimic a lock command. Cleaning the panel surface removes residue that interferes with touch sensitivity on digital models.
Check the door alignment if the code appears without user input. Misaligned doors trigger safety interlocks that the system registers as lock activation. Adjust hinges only after confirming the primary unlock sequence does not clear the display.
Verify Frigidaire Dishwasher Operation After Reset
Run a short rinse cycle on the Frigidaire Professional Dishwasher to confirm all controls respond after the LOC code clears. Monitor the panel for any return of the indicator during the test. Note the cycle completion time and any unusual sounds from the unit.
