My dishwasher was working fine one moment and off the next. We just had it serviced 2 weeks ago because the start button was flashing and needed to be reset apparently. Bow it's not working at all and there is about 1 inch of water in the bottom of it. It's an ultra wash quiet gaurd3

Those whirlpool's like to blow their fuses. Start with power to the dishwasher. Breaker, outlet, dishwasher junction box, fuse near main control panel.
