Crafted from anti-corrosion engineering plastic and premium copper coils, our valves maintain consistent water inflow and deliver an extended service life across all fully automatic washing machine models.
Cixi Lihe Electric Appliance Co., Ltd. specializes in the R&D and manufacturing of Fully Automatic Washing Machine Solenoid Valves. Also referred to as washing machine water inlet valves or dual-inlet solenoid valves, our products feature a dual independent channel design that enables precise hot and cold water control. Constructed with corrosion-resistant materials and high-grade copper coils, they deliver stable flow rates, rapid response (≤0.1s), reliable shut-off performance, and effective leak prevention. The valve is designed for broad compatibility across front-loading and top-loading washing machine platforms, and is suitable for both OEM production and aftermarket replacement applications.

Manufacturing Process & Quality Testing
Each Fully Automatic Washing Machine Solenoid Valve is produced through a series of controlled manufacturing steps within our Cixi factory, ensuring consistency and traceability from raw material to finished product.
Production workflow:
• Copper coil winding and insulation treatment to meet rated power and thermal stability requirements
• ABS body injection molding with metal insert integration for structural strength and corrosion resistance
• Precision assembly of diaphragm, plunger, spring and sealing components under clean-room conditions
• Automated welding of coil terminals and connector harness
Quality control tests performed on each unit:
• Coil resistance and electrical insulation test
• Sealing pressure holding test (0.02–1.0 Mpa, zero leakage acceptance criteria)
• Flow rate and response time verification
• Operating noise measurement
• Cycling endurance sampling test (batch-level, ≥100,000 cycles)
Our internal after-sales tracking records from exported products indicate that the annual reported field failure rate remains below 0.2% under normal operating conditions, reflecting the result of this multi-stage testing approach rather than an absolute guarantee.

Installation & Maintenance
Installation Steps
1. Disconnect both power supply and water source before starting installation.
2. Flush the inlet pipe to remove any scale or debris that could obstruct the valve.
3. Secure the inlet valve with appropriate torque (recommended 3–5 N·m) and connect outlet hoses firmly.
4. Verify supply voltage matches the valve rating, complete wiring connections, then restore water supply and check all joints for leaks.
Maintenance Note: Operate the valve within the rated pressure (0.02–1.0 Mpa) and temperature (0–100℃) ranges. Clean the inlet filter every 6 months to maintain consistent flow performance. For technical inquiries, contact our engineering support team.

Frequently Asked Questions
Q: How do I select the correct solenoid valve for my washing machine model?
A: Key selection factors include voltage rating (AC100–240V), thread size (standard 3/4 inch), number of water inlet channels (dual for hot/cold control), and physical mounting dimensions. We recommend checking your original valve's specifications or providing us with your washer model number for compatibility confirmation.
Q: What is the difference between this dual-channel valve and a single-channel inlet valve?
A: A dual-channel valve independently controls hot and cold water intake, enabling temperature regulation during wash cycles. Single-channel valves handle only one water source. Dual-channel designs are standard for modern fully automatic washing machines requiring both hot and cold water connections.
Q: What are the common signs that the solenoid valve needs replacement?
A: Typical indicators include: the washer fails to fill with water, water continues flowing when the machine is off, abnormal humming or buzzing noise from the valve area, visible cracks or corrosion on the valve body, or inconsistent water flow. We recommend inspection by a qualified technician before replacement.
Q: Can I install this valve myself, or is a professional required?
A: The installation requires basic tools (wrench, screwdriver) and involves electrical wiring and water connections. Users with DIY experience may perform the installation following the included instructions. However, we recommend professional installation to ensure safety and proper function. Always disconnect power and water supply before starting.
Q: What factors affect the service life of this solenoid valve?
A: Key factors include water quality (hard water may accelerate scale buildup), operating pressure (must stay within 0.02–1.0 Mpa), ambient temperature, and usage frequency. Regular cleaning of the inlet filter every 6 months helps extend service life significantly.
Q: Do you support OEM customization for this valve?
A: Yes. We offer customization options including wire harness length, terminal types, housing color, brand logo printing, and packaging design. Please provide your detailed specifications for a tailored quotation.
Q: What testing does each valve undergo before shipment?
A: Every unit passes coil resistance and electrical insulation testing, sealing pressure holding test from 0.02 to 1.0 Mpa with zero leakage acceptance, flow rate verification, and operating noise measurement. Batch-level cycling endurance testing (≥100,000 cycles) is also conducted.
Q: How does this valve compare with generic aftermarket alternatives?
A: Key differences include: 100% individual factory testing, copper coil construction for better thermal stability, ISO 9001:2015 certified production processes, and an annual field failure rate below 0.2% based on internal after-sales tracking data across major export markets.
