The dispenser door fails to open during the wash cycle, leaving detergent tablets or powder untouched — dishes come out dirty or with food residue remaining.
The module latch or spring mechanism is broken or worn, causing the door to stay stuck shut or hang open and unable to hold detergent before the cycle starts.
Insufficient detergent release due to a clogged or failed wax motor inside the module results in poor wash performance and cloudy or greasy dishes.
Hardened detergent deposits jam the dispenser mechanism, preventing the door from opening fully and causing uneven detergent distribution across the wash cycle.
A cracked module housing or damaged door seal allows water and detergent to leak onto the interior door panel, potentially reaching the control board.
The integrated rinse aid compartment within the module is damaged or its release valve has failed, causing streaky glassware or poor drying results.
💡 Pro Tip: Is Your Detergent Dispenser the Problem?
Your part is likely the culprit if you notice any of the following:
⚠️ Detergent remains completely undissolved in the cup after a full wash cycle
⚠️ Dispenser door does not spring open during the main wash phase
⚠️ Dishes come out with greasy residue or food still attached
⚠️ Visible cracks, warping, or a broken latch on the dispenser door
⚠️ Water or detergent leaking from the dispenser area onto the door panel
Before ordering, run a short cycle and watch the dispenser — if the door stays shut or only partially opens, the wax motor or latch inside the module has failed and the entire module should be replaced as a unit. Also check that the door panel wiring harness connector is seated; a loose connector mimics a failed dispenser.
