Frigidaire Dishwasher LOC Error Code: What It Means & What to Check

Q: My Frigidaire dishwasher is showing LOC. What does that mean, and what should I do?

A: On many Frigidaire dishwashers, LOC means the door/control lock is enabled. In many cases, this is not a failed part—it is a feature that prevents buttons from being pressed accidentally. The first thing to try is unlocking the controls using the lock button/key combination on the panel.

If the code will not clear, the buttons do not respond, or the dishwasher stays locked after a reset, there may be an issue with the user interface panel, touchpad, or control board. Our friendly technicians in yellow can help diagnose it safely.

What the Frigidaire Dishwasher LOC Code Usually Means

The LOC display typically indicates one of these conditions:

• Control Lock is turned on (most common)
• Child lock / panel lock mode is active
• A button is stuck, causing the panel to act locked
• User interface / touchpad issue preventing unlock input

Common Symptoms You May Notice

• Dishwasher display shows LOC
• Buttons do not respond when pressed
• Cycle will not start
• Only certain buttons respond
• Unit appears to have power but won’t operate normally

Safety First (Before You Start)

Good news: this code is usually a control setting, not a water leak or electrical emergency. Still, use normal appliance safety habits:

• Keep hands dry when pressing panel buttons
• Do not force buttons or pry on the control panel
• If you smell burning or see damaged wiring, stop and disconnect power at the breaker

Quick Checks You Can Try at Home

These are homeowner-safe checks that often clear a Frigidaire dishwasher LOC code.

1) Hold the Control Lock Button

Many Frigidaire models unlock by pressing and holding the Control Lock or Lock button for about 3 seconds (sometimes longer depending on the model).

• Look for a padlock icon or “Control Lock” label on the panel
• Press and hold the matching button steadily
• Wait for the display to change or the lock indicator to turn off

2) Check for a Secondary Button Combo

Some models use a different key (or key combination) to toggle the lock feature. If your panel labels are worn or unclear:

• Look for a small lock icon printed near a button
• Try holding the labeled button for several seconds
• Avoid rapid button pressing, which can confuse the control

3) Power Reset the Dishwasher

A simple reset can restore normal control panel behavior if the display is stuck.

1. Turn the dishwasher off (if the panel responds)
2. Shut off power at the breaker for about 5 minutes
3. Restore power
4. Try the unlock button again

4) Inspect the Control Panel for Stuck Keys

If a button is physically stuck or the touchpad is failing, the control may remain locked or show LOC repeatedly.

• Check for residue, moisture, or a button that feels different
• Do not spray cleaner directly on the panel
• Use a lightly damp cloth on the exterior only (if needed)

Common Causes / Likely Parts (If LOC Won’t Clear)

If the code remains after unlocking attempts and a power reset, these are common parts or areas a technician may inspect:

• User interface / touchpad panel (not registering unlock input)
• Main control board (software or relay/control issue)
• Ribbon connection / wiring harness between panel and control
• Stuck or shorted button circuit

When to Call Beacon

It’s a good time to schedule service if:

• You’ve tried the unlock button/hold sequence and the code stays on
• The panel is unresponsive after a breaker reset
• The dishwasher starts acting erratically (random beeping, partial button response)
• The code returns repeatedly after clearing

Our friendly technicians in yellow can test the control panel and electronics, confirm the cause, and help you avoid replacing the wrong part.
