The Water Inlet Tubing is an OEM part for Frigidaire dishwashers. This tubing allows water to flow from the home's water supply lines into the dishwasher. Properly functioning inlet tubing is essential for supplying water to fill cycles and operate through different wash and rinse cycles. Causes of a bad water inlet tubing can include mineral or sediment build up inside the tubing restricting water flow, splitting or cracking of the tubing material from stress or age, or damage from sharp objects or wear and tear. Symptoms of a bad water inlet tubing include: The dishwasher failing to fill properly or slowly filling. Fluctuations in water pressure during cycles. Excessively long fill times. None or intermittent water flow into the dishwasher. Leaks or water drips around the supply lines. This OEM Frigidaire part is also compatible with Electrolux, Gibson, Kelvinator and some Kenmore models.Part Number 5304523457 (AP6983752) replaces 154446002, 154577401, 154239801, 154446001.
