I have a Frigidaire dishwasher (Model #FFBD2406NS9B) and just within the last few day's I am unable to get it to run. The lights on the button's are still lighting up, and when you initiate a wash cycle is makes a clicking noise but never actually starts. As a little context, me and my wife purchased our house brand new 3 year's ago and the dishwasher was brand new as well. We've had issues with irregular water pressure (sometimes very high) as well as hard water. A few month's ago we finally installed a pressure reducer on the main water line and a Morton's water softener, not sure if this has anything to do with the Dishwasher not working but thought it might be necessary context to provide.

Im relatively mechanically inclined and can fix most thing's myself, but having trouble on where to start with something like this, I tried opening/closing multiple times to make sure the door was actually closed and that didn't seem to do anything. Where should I start?

Thank you
