Detergent dispenser blocked or malfunctioning

Part: Detergent dispenser and latch mechanism

Improper loading blocking water flow

How to Identify: Large items placed in front of spray arms or dispenser; overfilled racks limiting water reach.

Part: Water inlet valve

Expired or improperly stored detergent

How to Identify: Old or clumped detergent; pods appear degraded or hard to press.
