Need help?Do you have a question about the Panasonic NA-107VC4W01 and is the answer not in the manual?
This document is a service manual for the Panasonic NA-107VC4W01 drum-type washing machine, designed for the Indian market. It provides comprehensive information for experienced repair technicians, covering the machine's functions, technical specifications, usage, and maintenance.
The Panasonic NA-107VC4W01 is a front-loader drum-type washing machine with a 7 kg capacity. Its primary function is to wash, rinse, and spin-dry laundry. The machine features a control panel with an LED display and various function buttons and knobs, allowing users to select from 15 wash programs and 6 spin speed settings. Key components include a detergent drawer for dispensing detergent, softener, and pre-wash agents, a drum for washing and spin-drying, a door with a seal, a water-drain hose, and adjustable feet for leveling.
The washing process involves several stages: water intake, heating (if a hot wash is selected), washing, rinsing, and draining. The machine incorporates an electronic pressure switch (EPS) to regulate water levels and an NTC (Negative Temperature Coefficient) sensor to monitor water temperature, ensuring optimal washing conditions. A drain pump is responsible for expelling water from the machine. The motor, an asynchronous type, controls the drum's rotation for both washing and spinning cycles.
Safety features are integrated into the design, such as a child lock function to prevent unintended operation and a door lock mechanism that activates at the beginning of a program to ensure the door remains closed during operation. In case of an electric energy lack during a washing cycle, an emergency opening system (PTC-Bimetal) allows the door to unlock after a minimum of 60 seconds.
The machine also includes an "Autotest" mode for service technicians, which allows for a systematic check of various components and functions, including spin speed, heating, water intake, and pump operation. Failure codes are provided to help diagnose specific issues, such as door lock problems, lack of water, pump failure, overflow, NTC or heater failure, motor failure, and EPS errors.
The washing machine offers a variety of programs to suit different laundry needs, including "Cotton," "Cotton + PW" (Pre-Wash), "Cotton-Eco," "Colours," "Easy-care," "Wool," "Rinse," "Drain," "Spin," "Sportswear," "Bedding," "Shirts," "Rapid 15'," "Quick," and "15 °C Wash." Program details, including available temperature ranges, duration, energy consumption, and water consumption, are provided. The "Half Load Defection" feature adjusts program parameters for smaller loads, optimizing resource usage.
Users can adjust the spin speed and utilize a "Delay Start" function. The "Extra Rinse" function can be selected for additional rinsing. The LCD screen displays program information, selected settings, and indicators such as "Spin Phase Led," "Rinse Phase Led," "Wash Phase Led," "Child Lock Activation Led," "Door Lock Led," "Lack Of Water Indication Led," and "Pump Failure Indication Led."
The child lock feature is activated by pressing the fourth function button for 4-5 seconds, displaying a "CL" symbol on the LCD. Deactivation follows the same procedure.
The manual emphasizes several maintenance aspects for technicians. For installation, it details the removal of transportation screws, adjustment of feet for stability, and proper electrical and water connections. The drain pump filter should be cleaned regularly for better performance.
The document provides detailed instructions for disassembling and assembling various components, including the top plate, door, spring wire, detergent drawer, control panel, kick plate, front panel, upper support bracket, detergent drawer housing, power cable group, parasite filter, electronic pressure switch (EPS), door lock, pump motor, front counterweight, heater, tub bellows seal, transport screw, upper counterweight, washing group, shock absorber PIN, belt, driven pulley, motor, tub entrance with bellow hose, pressure switch hose group, tub, and drum. Torque values for critical fasteners are specified to ensure correct reassembly.
For troubleshooting, a comprehensive guide lists common failures, probable causes, and methods of elimination. This includes issues like the machine not operating, not receiving water, not draining, vibrating excessively, or producing excessive foam. It also addresses problems with washing results, residues on clothes, grey stains, and spinning issues.
Component checking procedures are outlined for the drain pump, resistance (heater), NTC, valve, EPS, motor, and door lock. These procedures involve using a multimeter to measure resistance or checking specific functions to diagnose faults. Wiring diagrams are provided to assist in tracing electrical connections. Exploded views and replacement parts lists are included for easy identification and ordering of components. The manual also highlights special safety components marked with a triangle symbol, emphasizing that these parts must be replaced with manufacturer-specified parts to prevent hazards.
