Bleach dispenser not releasing bleach at the right time

Symptoms

• Bleach still sitting in the compartment after the cycle
• Bleach released too early, bleaching clothes it shouldn't
• White residue crusted in the bleach compartment
• Faint bleach smell without visible whitening effect

Likely causes

• CommonDried bleach residue clogging the compartment or siphon tubeBleach can crystallize and block the small channels that control timed release.
• CommonOverfilling the bleach compartment beyond the fill lineToo much bleach can overwhelm the dispenser's designed release timing.
• PossibleLow water pressure preventing full flush of the compartmentThe dispenser relies on adequate water flow at the right cycle step to release bleach on time.
• Less commonFailed dispenser valve or siphon mechanismA mechanical failure in the dispenser can prevent it from working regardless of cleanliness.

What to do

1. Remove the dispenser drawer and thoroughly clean the bleach compartment, using an old toothbrush on any crusted residue.
2. Check the small overflow or siphon tube in the compartment for blockage and clear it gently.
3. Fill the bleach compartment only to the indicated line, never above it.
4. Confirm water supply valves are fully open for adequate flow.
5. Run an empty cycle with just the bleach dispenser filled with water to test if it releases at the correct point.
6. If bleach still won't dispense correctly after cleaning, have a technician check the dispenser valve mechanism.
