All right. If you've got a Frigidaire Gallery dishwasher with this type of display, in order to get it into diagnostic mode, you have to hold you have to get it to light up, and then you hold the first and the third buttons down, and then what'll happen is C3 will start to blink if you push the first button.
It will run through like firmware checks. If you push the second button, you can go through individual component tests. You can te test the water solenoid, the dishwasher door, the heater. You can check all of these things individually, but if you push the third button, what you'll do is you'll get a 13 minute that pops up.
And what that does is that means it will just run a basic 13 minute cycle to test. All of the individual things at one time. If you have any issues, it will throw up a trouble code and tell you which part is bad. Now again, you can push the second one and check these things individual. You can check the door switch, you can check the detergent door, you can check the heater, the water fill solenoid, the drain pump.
You can test all those things individually, but the third button, the third option just does all of it at once for you. So you hit start, everything lights up, and then you just shut the door and it takes care of it.
