Frigidaire dishwasher model# FDB1500LFC2, approx. five years old.

No previous issues. Ran washer while I was out of house. Opened to unload that night, dishes were still dirty on the bottom and top rack. Ran again to listen to problem. Bottom is filling up with water, all lights on control panel indicate it is working. When it finishes fill, it usually pauses and then you can hear noise of sprayer arms working and some motor noise. However, now it finishes fill and is silent, no washer arms moving, no spray, no motor noise, it is silent. I have removed and cleaned the sprayer arms and food traps. Removed the stem housing, and the propeller assembly under that seems in working order. Not sure where to look next. I need help troubleshooting.

Thanks!
