Symptoms
- Detergent pod or powder still sitting in the cup after the cycle
- Dishes come out with a visible film of dried soap
- Dispenser door won't click shut when loading
- Cycle finishes but dishes seem unwashed
Likely causes
- CommonDispenser blocked by a dish or utensilA tall dish or pan lid on the top or bottom rack can physically block the dispenser door from swinging open.
- CommonDetergent clumped or expiredDetergent exposed to moisture in the cup can harden and fail to dissolve or release properly.
- PossibleDispenser latch or spring worn outThe small spring-loaded latch that holds and releases the door wears out over time.
- PossibleWax or film buildup on dispenser hingeOld detergent residue can gum up the hinge so the door doesn't swing freely.
- Less commonWiring or solenoid failure on the dispenserAn electrical failure in the dispenser's release solenoid stops it from firing on cue.
What to do
- Check that no dish, pan, or utensil is positioned in front of or above the dispenser cup blocking it.
- Make sure the dispenser lid is fully closed and latched before starting the cycle; you should hear or feel a click.
- Wipe out the dispenser cup and hinge area with a damp cloth to remove old, hardened detergent residue.
- Use fresh, sealed detergent pods or powder rather than product that's been exposed to humidity in an open container.
- Run the dispenser door open and shut by hand outside a cycle to check the spring and latch move freely.
- If the door won't open during a wash cycle even when clear and clean, the release mechanism likely needs replacement.
