The 5304514365 is a genuine OEM Frigidaire-family dishwasher circulation pump & motor assembly. This is the main wash pump that recirculates water from the sump through the spray arms at high pressure to clean dishes. It replaces 240550925, A00210602, A00210627. When it fails, the dishwasher may still fill and drain but will have weak/no wash action, loud grinding/whining from the sump area, or may stop mid-cycle during the wash portion. Common failure modes include worn motor bearings, a damaged/jammed impeller from debris (glass/bones/labels), electrical winding failure, or seal leakage causing water intrusion into the motor. IMPORTANT: Poor cleaning can also be caused by clogged filters, blocked spray arms, low fill level, or low water temperature—confirm before replacing. CRITICAL: Turn off breaker and water supply before servicing.
