Understanding the Problem
If your LG WT7600's bleach dispenser never fills during the wash cycle, the machine won't deliver bleach to the drum and clothes won't be sanitized as expected. The dispenser relies on a timed valve/opening that routes cold water into the bleach chamber. Problems can come from a blocked dispenser, a failed water inlet valve or solenoid that feeds the dispenser, kinked or clogged tubing, or an electronic/control issue preventing the valve from being energized. Begin troubleshooting by confirming the washer is receiving cold water (the bleach dispenser normally fills from the cold inlet) and that detergent/softener settings aren’t interfering. Often the repair is mechanical and simple: cleaning the dispenser and screens or replacing the inlet valve. If the dispenser still doesn't fill after cleaning and confirming water pressure, you'll need to test the inlet valve and wiring, or replace the dispenser assembly or main control board depending on diagnostics.
Common Symptoms
Bleach stays in the dispenser or overflows without being flushed, no water enters dispenser during the fill/drain points, clothes not bleached/sanitized, occasional error codes or long fill times.
Common Causes
- Clogged dispenser, siphon-break, or dispenser outlet preventing water flow
- Faulty water inlet valve or solenoid that feeds the bleach dispenser (no open/close action)
- Blocked/kinked dispenser tubing or a control/board/wiring failure preventing the valve from energizing

Helpful Repair Tip
Run a diagnostic or time a cycle and listen for a distinct "click" when the valve is supposed to open; no click plus no continuity on the valve solenoid means the inlet valve is likely the culprit.
Frequently Asked Questions
Can I still use bleach if the dispenser doesn't fill?
You should avoid pouring bleach directly into the drum as it can damage fabric and rubber parts if not diluted correctly. Instead, troubleshoot the dispenser (clean, check water supply, test valve) or add bleach pre-diluted into the final rinse if you understand the washer's cycle timing. Best practice is to repair the dispenser or replace the faulty component.
How do I test the water inlet valve on my LG WT7600?
First turn off power and water. Remove the back or top access panel to reach the inlet valve. Visually inspect for debris on the inlet screens. With the cycle set to a point that should open the dispenser valve, restore power briefly and listen for a click. For an electrical test, disconnect the valve harness and measure solenoid continuity with a multimeter (typical solenoids show low ohms). No continuity or no click indicates a bad valve. If the valve tests good but there is no signal, trace wiring and test the control board outputs.
