HEX NUTS

Brackets, gussets, clamps, and fasteners keep assemblies aligned under vibration. Loose mounting leads to noise and repeat failures. Symptoms can present as fasteners not holding, intermittent operation, abnormal noise, or a cycle that won’t complete normally—depending on where this part sits in the system. If the fault changes with vibration or after moving panels, look for borderline fitment, loose connectors, or wear marks around the installation area. Diagnosing fasteners not holding can come down to one worn component—Hex Nuts (part 03-1406-12) is a common replacement item. Disconnect power before service. Reinstall so nothing pinches, rubs, or binds once the unit is back together. Replacing a worn part early can prevent secondary damage to nearby components. Recheck fasteners after a short run-in period; vibration can loosen hardware if it isn’t seated correctly. Recheck fasteners after a short run-in period; vibration can loosen hardware if it isn’t seated correctly. If the part interacts with water, do a leak check during the first run and again after a short operating period. Clean the area around the repair so debris doesn’t interfere with fitment or sealing surfaces. If the part interacts with water, do a leak check during the first run and again after a short operating period. Recheck fasteners after a short run-in period; vibration can loosen hardware if it isn’t seated correctly. Take a photo before disassembly so you can confirm orientation and fastener locations during reassembly.
