Melting water drain nut

Water pooling beneath your ice machine during the harvest cycle often originates from a melting water drain nut that can no longer maintain the compression seal against the drain line connection. This 1864608300 melting water drain nut secures the drain tube to the evaporator trough or drain pan, ensuring that meltwater from the defrost cycle routes exclusively to the building drainage system. When this fastener corrodes, strips, or loosens from vibration, youll observe symptoms including water leaking onto the floor during harvest, ice buildup beneath the machine from accumulated leakage, and potential slip hazards in the equipment area. Technicians encounter this issue frequently during routine maintenance when the drain assembly is disturbed for cleaning purposes. The nut works in conjunction with a compression washer or O-ring to create a watertight seal; if youre replacing this hardware, inspect the sealing surfaces for calcium buildup that prevents proper seating. Overtightening cracks the plastic drain fitting, while undertightening allows the connection to weep under the pressure of rapid meltwater flow during defrost. Stainless steel construction resists the corrosion inherent in constantly wet environments. Installing this replacement melting water drain nut restores the secure connection that prevents water escape during the high-flow harvest period. The precise thread specification matches the OEM drain fitting, preventing the cross-threading damage caused by generic hardware substitutions. For repair professionals, this component addresses water leaking during harvest, ice under machine, and drain line disconnected complaints that indicate fastening system failures rather than drain line blockages.
