WM Water Sensor B03150054

Description

Based on the item you are currently viewing, here is the dedicated product description and system compatibility guide for this specialized laundry part:Product DescriptionThe Haier B03150054 Water Level Pressure Sensor (frequently cross-referenced with the B0315 series or structural configuration number CGQ-1) is an OEM-grade electronic water level switch. It is engineered specifically for modern fully automatic washing machines that utilize a 3-pin low-voltage digital control loop.This sensor plays a critical role in your washer’s cycle management by monitoring the air pressure displaced by the water level inside the tub. As water enters the machine, it pushes air up through an attached 1/4″ rubber pressure tube and into the sensor’s top nozzle. The internal diaphragm deflects, altering the frequency output of an onboard induction coil. Once the frequency corresponds to your chosen water level, the main control board halts the inlet valve to initiate washing. Swapping out a malfunctioning B03150054 component resolves common problems such as constant tub overfilling, failure to advance past the fill cycle, or “E4” / “PE” error codes flashing on the panel.Key Features & SpecificationsModel Designation: B03150054 / CGQ-1 Architecture BaseElectrical Rating: DC 5V | 10mA (Low-voltage digital frequency control logic)Terminal Interface: 3-Pin male wire harness socket connectionHousing Build: High-durability, moisture-sealed white polymer chassis with a distinctive circular blue or grey accent ring and integrated structural mounting ears.Pneumatic Port: Single tapered top-facing air nozzle built to form a vacuum-tight seal with standard pressure tubes.Compatible Machines & ModelsThe B03150054 / CGQ-1 pressure switch is a standardized component widely deployed across several regional and international top-loading automatic washer lines:Haier Fully Automatic Washers:Natively engineered for various mid-capacity to high-capacity Haier automatic models requiring a 3-pin 5V DC control logic loop.Damro & Innovex Top-Loaders:Directly functions as a direct drop-in replacement part for Innovex and Damro automatic washing machines configured for a 3-pin connection pattern.Singer Top-Loading Washers:Fits several regional Singer automatic laundry platforms utilizing the standardized round induction-style pressure valve ecosystem.Midea & Little Swan Platforms:Matches select electronic Midea top-load configurations utilizing standard DC 5V sensor frequency matrices.💡 Fitment Check Tip: The B0315 series shares an outer structural profile with other legacy switches, but is optimized for modern 3-pin digital control loops. Before purchasing, always look closely at the plug receptor on your broken component to confirm it contains three distinct metallic pins arranged linearly, ensuring full electronic compatibility with your washer’s circuit board.
