Safety Warning: Prioritize safety: always unplug your dishwasher from the wall outlet and shut off related water or gas valves before removing access panels.
Check Water Temperature
Tablets need water to be around 120°F (49°C) to dissolve properly.
- Run your kitchen sink tap on hot before starting the cycle to bring hot water to the line faster.
Inspect the Spray Arms
The tablet requires direct spray from the arms to wash it out of the tray.
- Remove the bottom and middle spray arms and clean out any clogged holes using a toothpick.
- Ensure the arms can spin freely without hitting tall dishes.
Dispenser Door Malfunction
Check if the latch spring is broken or gunked up.
- If the door is blocked by tall plates in the lower rack, the tablet won't release into the tub.
- If the electronic actuator fails, the entire dispenser assembly needs replacing.
