Understanding the Problem
If the bleach dispenser on your LG WT7 washer never fills or only partially fills, the washer will not deliver bleach during the wash and stains or sanitizing steps can be missed. The dispenser relies on a timed valve/solenoid and the machine's water inlet path. A failure anywhere between the cold water supply and the dispenser cup can prevent water from reaching the bleach chamber. Common areas to check include the water inlet valve (the solenoid that lets water into the washer), any internal diverter or dispenser solenoid, clogged screens/filters or kinked inlet hoses, and the dispenser assembly itself. Electrical faults (no signal to the solenoid) and control board issues are less common but possible if the valve is not being energized during the appropriate point in the cycle.
Common Symptoms
Bleach cup never fills or fills late/slowly; washer otherwise fills for wash/rinse cycles; no audible click from inlet valve at bleach fill time; visible clog or buildup in dispenser cup/ports.
Common Causes
- Clogged dispenser ports or internal screens (residue buildup restricting flow)
- Faulty water inlet valve or dispenser diverter solenoid (no water flow to bleach cup)
- Kinked/blocked inlet hose or shutoff valve partly closed; electrical/control signal failure to valve

Helpful Repair Tip
Run a rinse-only or diagnostic cycle and watch the water inlet hose/dispenser area; if the washer fills but the dispenser stays dry, suspect the dispenser/diverter or clogged port. Use a multimeter to check inlet valve coil continuity and listen for the inlet valve click when the fill should occur.
Frequently Asked Questions
How do I test the water inlet valve on my LG washer?
Unplug the washer and turn off the water. Access the inlet valve at the rear panel. Remove the wire harness and use a multimeter to check each solenoid coil for continuity (typical reading: several hundred to a few thousand ohms). To confirm operation, restore power and have a helper start a cycle that should open the valve, then listen for a click at the valve or carefully test voltage at the connector (usually ~120V) when the machine should fill. Only measure live voltage if you are experienced and take safety precautions.
Can a clogged bleach dispenser be cleaned or do I need to replace the part?
Often the dispenser cup and its small ports can be cleaned of detergent/bleach residue and restored to normal function. Remove the dispenser assembly and soak/brush it, and clear any visible buildup in the port that routes water to the bleach cup. If the internal diverter valve or solenoid is damaged or the dispenser housing is cracked, replacement will be necessary.
