The Fine Filter is an OEM part for Frigidaire dishwashers. It plays a critical role in trapping food particles and debris, ensuring that only clean water circulates during the wash and rinse cycles. This helps maintain optimal cleaning performance and prevents clogs in the dishwasher's drain system. Over time, the fine filter can become clogged with food particles and debris, or it may suffer damage that reduces its effectiveness. Causes of a bad fine filter include neglecting regular cleaning, buildup of mineral deposits, and physical damage from sharp objects or heavy items. Symptoms of a bad fine filter include: Poor cleaning results, with food particles left on dishes Water not draining properly from the dishwasher Unusual noises during the wash cycle due to restricted water flow Frequent clogs in the dishwasher's drain system This OEM replacement is also compatible with Electrolux, Gibson, Kelvinator, and Kenmore models.Part Number 5304506533 (AP6036343) replaces 154775401, 154252301, 154332602, 154775402, 154776101, 154252201, 154252302, 154332601, 154758901, 4456343, PS11770494.
