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.
