Understanding the Problem
On LG top-load washers like the WT7600 the bleach dispenser only receives water during a specific rinse portion of the cycle. The machine’s control board signals a water inlet valve or dispenser diverter to route water to the bleach cup so the bleach is diluted and introduced at the correct time. When that cup stays dry the bleach either never dispenses or is dumped into the wash load at the wrong time, reducing effectiveness and risking fabric damage. Several different issues can stop water from reaching the bleach dispenser: a clogged dispenser or internal tubing, a failed water inlet valve or dispenser solenoid, or an electrical/control fault that never opens the valve. A proper diagnosis looks at both the mechanical path (screens, hoses, dispenser assembly) and the electrical path (valve energizing, control signals). Replacing parts without testing can be expensive and unnecessary if the problem is just a blockage or kinked hose.
Common Symptoms
Bleach cup remains dry during rinse, no water flowing into the bleach compartment, bleach being dispensed at wrong time, washer otherwise fills and spins normally.
Common Causes
- Clogged dispenser cup, screens or internal tubing preventing water flow
- Faulty water inlet valve or dispenser solenoid failing to open during rinse
- Control board/timer not sending the signal to open the valve or a wiring harness fault

Helpful Repair Tip
Run a diagnostic/rinse cycle and listen for a click at the water inlet valve during the rinse — if you hear the valve but no water, check the inlet screens and dispenser tubing first; if you don’t hear the valve click, test the valve for continuity or check the control board signal.
Frequently Asked Questions
How can I test whether the water inlet valve is the problem?
Run a rinse cycle and listen for a click at the valve when the machine should route water to the bleach cup. If you hear a click but no water, clean the inlet screens and dispenser lines. If you don’t hear a click, shut power, unplug the washer, and test the valve coils for continuity with a multimeter (expect low ohms). Also check for voltage at the valve during the rinse (only with power on and safe precautions) — no voltage indicates a control or wiring issue rather than the valve itself.
Can I still use bleach if the dispenser doesn't fill?
You can add bleach directly to the wash water in small amounts, but this risks uneven dilution and fabric damage. It's better to fix the dispenser so bleach is introduced at the correct time and concentration. If you must add it manually, add bleach during the first rinse and dilute it in a cup of water before pouring and avoid using on delicate fabrics.
