How to Troubleshoot & Replace Frigidaire AP6327227 / 5304514670 Main Control Board

Replace the control board for the 2nd time. Please be careful purchasing this model of dishwasher. Look online for the repair issues 

Ordered a new control board 

Contacted customer service trying to troubleshoot dishwasher problem. Spoke with very helpful lady who worked through issues. She and tech decided it was control board. I got off phone and ordered part by 4:00 pm. I had the part the next morning and in 10 minutes dishwasher was running. Customer service like this is near non-existent these days, especially with the big box places. They helped me without knowing I would buy part from them. I will not hesitate to use this company anytime I have appliance issues or just need parts. 

The problem started because the dishwasher would not fill with water. At first it was believed to be the water control valve. it was replaced but the problem was still there. Ran some test with a volt meter (Not sure I really did them right) and it did not appear as the water inlet valve was not getting any power. Check a couple of other connections and that did not show any power either. Order the control board and waited for its arrival. The control board is located inside the door so I located 8 screws on the inside of the door and when they were undone the door fell off onto the floor. Control panel was then located in its protective plastic box. The old one was removed by taking out the screws and unplugging it. the connecting the new control board and plugging up all the connections. Turned the water and power back on to the system and tested it and it ran like it was supposed to. Turned off the water and power again and reassembled the washer and it has worked ever since. 

I did some research and discovered the mother board needed to be replaced. The dishwasher works perfectly now and I saved hundreds of dollars in not having to purchase a new dishwasher. I'm not a technician, but the swapping out of the computer board was very easy. 

In reading other user's posts, I inferred that it was a possible board problem, not the control panel. I took a chance and ordered the board and it only took a couple of days to get it! It only required to take out six screws for access, then three screws to take out the board. It was a simple job to replace it. I'm a techie, so it was like replacing a motherboard on a PC. It took about 15 - 20 minutes to do, most of the time was spent trying to get the panel back on properly. In the past, I've used Appliance Pros to get the replacement part for the ice maker on my refrigerator. That came within three days! The videos are a plus, too. I will definitely use them again! 

I went online and found a YouTube video that explained what the most likely fix was. Control panel or power board. I decided if I was going to disassemble the unit, I chose to replace both. The video at AppliancePartsPros.com was very helpful. I watched it twice to be sure I was ready to do the job. Smooth procedure. Thanks to the video. 

Purchased model replacements 

Replaced the Control Board. I felt only about 90% certain that the replacement Control Board would fix the problem. There was no way to troubleshoot further than to try a new board. I had monitored the power (120VAC) at the door switch using a MIN/MAX Volt Meter during a cycle. After it stopped with pf display, the Voltage had dipped no lower than 118V. I concluded that source power (circuit breaker, wiring connections) was not the problem. I did not find anyone or any website that had experienced my exact symptoms. Most places only suggested checking the incoming power in case of pf code (which means Power Fail) I was relieved that I had not thrown away $150 when the replacement board fixed the problem. 

Did some online research and found this type of problem is typically a "control board" problem. Ordered a new control board from AppliancePartrsPros.Com. Arrived in two days with standard shipping. Installed the new board (found a YouTube video that showed all the steps). Took about 20 minutes total to install and reassemble the door assembly. Have run several loads and the problem looks to be solved. AppliancePartsPros had the best pricing for a new board. Shipping was very reasonable and very fast. I'm a happy camper!
