Function & Importance of the Washer Water Inlet Valve

The CW-400 water inlet valve is responsible for controlling and directing water flow into the washing machine drum during wash, rinse, and fill cycles.

Inside a washer system, it:

• Opens and closes electronically based on cycle commands

• Mixes hot and cold water (if dual inlet system is used)

• Ensures correct water pressure and volume for each wash stage

Because it is a critical water control component, OEM-level precision is essential to avoid overfilling, underfilling, or cycle interruptions.

Why OEM Quality Matters

Using a genuine Robertshaw OEM valve ensures:

• Proper electrical response to washer control signals

• Accurate water flow calibration for wash cycles

• Long-term durability under continuous water pressure

• Reduced risk of leaks, flooding, or cycle failure

Inferior or mismatched valves can result in inconsistent filling, slow wash cycles, or premature failure due to incorrect flow design.

Common Symptoms of a Faulty Washer Inlet Valve

If your washing machine is experiencing any of the following issues, the CW-400 may need replacement:

• Washer not filling with water

• Extremely slow water intake

• Washer overfilling or not stopping water flow

• No hot or cold water entering the drum

• Incomplete wash or rinse cycles

• Error codes related to water supply or fill failure

These issues typically indicate a failing inlet valve solenoid or internal blockage, directly impacting washer performance.
