Frigidaire Dishwasher Won’t Start — What’s Happening
A Frigidaire dishwasher that won’t start is a symptom, not a single fault code. It’s most often caused by a delay start setting counting down, control lock blocking button presses, a power interruption, or the door not being fully latched. Frigidaire’s error guide confirms that codes 01–24 mean Delay Start is enabled, PF means a loss of power, and LOC indicates Control Lock or Child Lock is active.
If the display is blank or unresponsive with no code showing, Frigidaire points first to the door not being closed and latched successfully. The unit will not begin any cycle until it detects a secure latch signal. Power interruptions or stuck buttons on the touch panel can also mimic a locked or dead control.
Most Likely Causes
- Delay Start is active (01–24 on display) The dishwasher is waiting for the countdown to reach zero before it begins the cycle.
- Control Lock is enabled (LOC on display) The control lock or child lock feature is blocking all button inputs until you unlock it.
- Door not fully latched The door did not click shut, or a misaligned rack or damaged latch prevents the switch from signaling that it’s safe to start.
- Power interruption or breaker issue (PF on display) The unit lost power and must be reset before it will accept a new cycle command.
- Stuck or unresponsive touch button A button on the control panel is stuck or the touch membrane has failed, mimicking a locked control.
- Failed door latch switch The latch may close physically but the switch inside does not signal the control board that the door is secure.
- Control panel or main control board failure If the panel remains dead after all resets and the latch is good, the user interface or main board may have failed.
How to Diagnose and Fix
- Check the display for 01–24 and cancel Delay Start if present, then restart the cycle.
- Look for PF on the display and clear it by pressing Start/Cancel or performing a full power reset at the breaker.
- Check for LOC on the display and hold the Control Lock button combination for 3 to 5 seconds until the indicator clears.
- Close the door firmly until you hear a click, then inspect the latch area for a misaligned rack, debris at the seal, or a loose latch.
- Turn off power at the breaker or unplug the unit for a few minutes, restore power, and attempt to start a cycle.
- Remove the inner door panel to inspect the latch assembly, verify the switch actuates when the door closes, and check wiring for corrosion or heat damage.
- If the latch is good but the panel stays unresponsive, test for signals from the user interface to the main control board.
- Replace the latch assembly or latch switch if engagement is weak or the signal is inconsistent, or replace the control panel or main board if no input registers.

When to Call a Pro
If you’ve canceled Delay Start, unlocked Control Lock, confirmed the door latches with a solid click, and completed a full power reset but the dishwasher still will not respond, call a technician. The next steps require removing the inner door panel to test the latch switch circuit, inspect wiring for damage, and diagnose whether the user interface or main control board has failed. Attempting board-level diagnosis without a meter and wiring diagram risks further damage or unsafe conditions.
