"PF" code showing on Frigidaire dishwasher

Model Number: FDB4315LFC0
Brand: Frigidaire
Age: 1-5 years

So the problem I'm having is that our dishwasher first had a vent error, that is fixed thanks to the vent assembly part from here. The test cycle shows a rinse aid error but I have suspicions that it may not be that in actuality as the error doesn't come on until about 5-10 minutes are left in the cycle. It also doesn't matter if it's on heated or air dry. Any thoughts? i could replace the soap dispenser but I want to make sure I eliminate everything else.

The "PF" error code on this dishwasher stands for "power failure". This error code will display if you shut off the power to the dishwasher, or if there was a power outage. You can normally just clear the code and run the dishwasher if there are not any other issues. It can also be caused by a bad electrical connection. Shut off the power to the dishwasher and check the electrical connections where the power comes into the dishwasher.

Yeah I've checked all the power connections, had to when I basically completely uninstalled the dishwasher to replace the vent assembly. I think i may try replacing the dispenser and see if that does the trick.

Is it coming up with a different error code for the dispenser?

only in the test cycle. I get the ra code when it gets to step 7 or so.
