Frigidaire Dishwasher will not start but has power

[Jamoe]

Model Number: LFID2426TF4A
Brand: Frigidaire
Age: 1-5 years

A friend of ours gave us a dishwasher he had only had for about 3 years. It was operational before we installed it at my house. Right now it has power, but will not start. When I push start and close the door, the start light goes from solid to blinking. I have changed the door switch/latch, and the control board. Not sure what else to do. Need help. Thanks

Did you turn on delay start by accident? Try pressing and holding the START/CANCEL button for 3 seconds to cancel the delay start option.

Did you replace the main control board or the user interface control board with the buttons?
