A common issue affecting many Frigidaire Dishwasher models is that the lock stays on, and one cannot operate the dishwasher. This can happen due to a fault in the display control board, or the unit may simply need to be reset. Here we will discuss the steps necessary to unlock a Frigidaire dishwasher and reset it.

According to the model you have, there should be a lock icon below the heat/dry button or the rinse-only button. To unlock your Frigidaire dishwasher, hold down applicable the heat/dry button or the rinse only button for 3 to 5 seconds. Doing so should turn off the lock light, and your Frigidaire dishwasher will now be unlocked. If this doesn’t work, try unplugging your dishwasher or flip the circuit breaker into the OFF position for about 10 minutes. After that, turn on the dishwasher by plugging it back in or flip the circuit breaker into the ON position. Doing so will reset the display control board on your Frigidaire dishwasher. This should normally fix the issue of the dishwasher not unlocking.

If following the above procedure does not solve the issue, then you may have a faulty display control board. This can happen due to a short circuit somewhere inside the control board, and it will need to be replaced. Look up the owner manual of your Frigidaire dishwasher and find the part number of the display control board. Replacing the old display control board with a new one should fix the issue, and your dishwasher should now be unlocked and ready to use.
