Dishwasher stops running

[farrell46]

I have a Frigidaire FPHD2491KF0 dishwasher, about 1 1/2 years old. The dishwasher will run for 15-20 mins then stops running or atleast the pump does. I'm not sure if the board is bad or there's away to test it.

Check for 120vac at the motor.

When the dishwasher is running it has 120 volts, when it stops nothing. I've also noticed if you open the door for a couple mins and close it, it will run for about a min or less than stop again

I replaced the main board today, the dishwasher came to life, however it will not go into rinse only mode now. I'm also not sure if the clean light is working.
