Understanding the Problem
On the LG WT7600 top-load washer the bleach dispenser is filled by a short, timed flow of water routed through the dispenser housing. If the bleach compartment never receives water during the wash cycle the washer will not dilute and add the bleach as intended. Typical operation relies on a working water inlet valve (cold fill for bleach), a clear dispenser funnel/hose, and an actuator or solenoid/diverter that opens at the correct time under control of the main control board. When the bleach cup stays dry the issue can be a plumbing problem (blocked or kinked hose, clogged dispenser), a failed water inlet valve or solenoid that doesn’t open, or an electronic/control issue that never signals the dispenser to fill. Diagnosing requires checking water supply and pressure, visually inspecting and clearing the dispenser and funnel, and testing electrical parts with a multimeter and by running service diagnostics if available.
Common Symptoms
Bleach compartment remains dry during wash; machine otherwise fills and spins normally; no visible leak; sometimes an audible click or no sound at the dispenser fill time.
Common Causes
- Clogged or obstructed dispenser funnel/hose (residue or mineral buildup)
- Faulty water inlet valve (cold) or weak inlet valve solenoid not opening
- Broken dispenser diverter/solenoid or dispenser assembly (mechanical failure)
- Kinked or disconnected dispenser pickup hose between cup and tub
- Low incoming water pressure or closed/partially closed supply valve
- Control board or timer failing to energize dispenser solenoid

Helpful Repair Tip
First run a dispense test or diagnostics (LG service mode) and listen for a click at the dispenser time; if you hear the click but no water, check the inlet valve and dispenser hose for blockage. If you hear no click, test dispenser solenoid/control output with a multimeter.
Frequently Asked Questions
How can I quickly tell whether the inlet valve or the dispenser assembly is at fault?
Run a dispense cycle or a service diagnostic and listen for a click at the time the dispenser should fill. If you hear a click but no water, the valve side or water supply is likely the problem (check inlet valve, screens, and supply pressure). If you hear no click, the solenoid/diverter or the control board may not be energizing the dispenser — test the solenoid for continuity and check for voltage during dispense in service mode.
Can I still use bleach if the dispenser won’t fill?
You can manually add properly diluted bleach directly to the tub at the start of the wash only if you carefully follow laundry and safety instructions (never pour undiluted bleach directly on clothes). However, manual addition may not be safe for all loads or cycles and can cause fabric damage. The recommended fix is to diagnose and repair the dispenser/inlet components so bleach is added and diluted at the correct time.
