My Frigidaire dishwasher 650, 690 series is not working right, the water isn't getting dispersed to the spinners and they're not letting any water into the machine. I checked the water flow, it's getting to the dishwasher fine, but it pools at the bottom. the heater seems to be working fine. I think that it may be an electrical problem, but I'm not sure. Any help would be much appreciated.
