After reading other reviews about what may be the issue with my Frigidaire FDB1500LFB2 Dishwasher, I quickly learned that the probable cause of the dishwasher not functioning was the Water Inlet Valve. This is exactly what it was. Swapping it out was fairly straightforward, especially after watching the helpful video here on AppliancePartsPros.com Once I had the old part out, I examined it to try and determine what failed, yet couldn’t see any issues, so it must have been internal somewhere. Regardless, once I swapped it out, the dishwasher worked like normal.
