Understanding the Problem
If your LG WT7600HK washer's bleach dispenser never gets water, the washer may still fill normally while the bleach cup remains dry, or the bleach may sit in the cup and never be flushed into the drum. This is usually caused by a blockage in the dispenser path, a failed inlet/diverter that supplies the dispenser, or the control not calling the valve at the right time. Bleach not dispensing can leave stains on clothing if added manually at the wrong time and prevents proper sanitization. Start with simple checks: make sure the bleach cup is seated correctly and not clogged with hardened residue, verify cold-water supply to the washer is turned on, and confirm other fill functions (like main tub fill) operate normally. If physical clearing and supply checks don’t fix it, the problem commonly lies in the water inlet valve or the dispenser assembly (including small tubing or diverter components) or an electronic control that fails to actuate the valve during the bleach fill step.
Common Symptoms
Bleach cup never fills during cycles; washer fills but bleach remains in dispenser; sporadic dispensing; visible clogging/residue in dispenser; loud click missing when dispenser should be supplied.
Common Causes
- Clogged or hardened bleach residue in the dispenser cup or internal dispenser tubing
- Blocked/dirty inlet hose screens or supply sediment limiting flow to the dispenser
- Failed or weak water inlet valve (solenoid) or diverter that supplies the dispenser
- Dispenser assembly (tray/diverter) cracked, stuck or otherwise failed
- Control board or timer not sending signal to the inlet valve at the bleach-dispense step

Helpful Repair Tip
Run a cycle that should use the bleach dispenser (or a diagnostic/rinse cycle), watch the dispenser during the fill step and listen for the inlet valve(s) clicking. If you hear the valve but no water, remove the dispenser and inspect/clear the tubing and screens; if you don’t hear the valve energize, test inlet-valve solenoids for continuity with a multimeter.
Frequently Asked Questions
How do I tell if the water inlet valve or the dispenser assembly is the problem?
First, remove and inspect the bleach cup for hardened residue or visible clogs and flush it with water. Next, run a cycle and listen for the inlet valve clicking when the bleach step begins — you should hear a click and water flow toward the dispenser. If you hear the click but no water at the cup, inspect the small tubing and screens between the valve and dispenser for blockage. If you don’t hear the valve click, remove the console/panel and test the valve solenoids for continuity with a multimeter and check for 120V (or appropriate voltage) being sent to the valve during the bleach step. If the valve is getting voltage and has continuity but does not open, replace the inlet valve. If the valve works but the dispenser tubing or drawer is clogged or damaged, replace the dispenser assembly or tubing.
Can I pour bleach into the washer manually if the dispenser isn't working?
You can manually add diluted bleach directly into the tub at the correct time (typically after the wash fill and before the rinse) but be careful: adding undiluted bleach directly onto clothes can cause spotting or fabric damage. Always dilute bleach in at least a liter of water before adding and add it while the drum has water and is agitating so it is distributed. Manually adding bleach is a temporary workaround — you should still diagnose and repair the dispenser to ensure correct timing, dilution and safety.
