Symptoms
- Rinse aid level indicator doesn't seem to drop over time
- Dishes still spotty or wet despite refilling rinse aid
- Rinse aid cap won't close properly
- Dispenser dial set very low
Likely causes
- CommonDispenser dial set too lowMany dispensers have an adjustable setting from low to high; a low setting releases very little.
- CommonCap not sealing or closing correctlyAn improperly seated cap can prevent the dispenser from releasing product on cue.
- PossibleDispenser mechanism gummed up with residueDried rinse aid or detergent overspray can jam the small release door.
- Less commonFailed rinse aid dispenser motor or wax motorThe small actuator that opens the dispenser during the rinse phase can fail electrically or mechanically.
What to do
- Check the rinse aid dial (often near the fill cap) and turn it to a mid or higher setting.
- Make sure the cap clicks fully closed after filling; a loose cap can leak or fail to seal for release.
- Wipe around the dispenser opening to remove any dried residue that could block the release door.
- Run a cycle and check the rinse aid level before and after to see if it's dropping at all.
- If the level never drops even on a high setting with a properly closed cap, the dispenser motor may have failed.
- Have a technician test or replace the rinse aid dispenser unit if it's confirmed not releasing product.
