Analysis of common fault maintenance methods for Whirlpool washing machines
The quality of Whirlpool washing machines has always been recognized by consumers and industry insiders, but this does not mean that Whirlpool washing machines will not have any failures at all. Let's learn some about Whirlpool washing machines maintenance methods and common fault codes with us. Analyze content knowledge. Analysis of common fault codes of Whirlpool washing machines f1: The water level sensor is in poor contact e1: Drainage timed out, check whether the drain pipe is blocked or the safety switch is faulty : The water intake is overtime, check the water pressure, and whether the water inlet valve is dirty and blocked e5: The water temperature exceeds 50 degrees"pf"——power failure"fl"——flood condition The water level in the bucket is too high"lf"——long fill The water intake time is too long. (10 minutes)"ce"——communications error signal disorder (cannot recognize computer board commands)"ld"——long drain draining time is too long Whirlpool washing machine repair method When washing, the motor runs normally in the forward and reverse directions, while the pulsator can only reverse in one direction, and cannot rotate forward Analysis and maintenance: This fault is caused by the deformation of the clutch pawl fork or the rotation of the adjustment screw If it is too deep, the working position of the pawl cannot be in place, resulting in that the washing shaft and the dewatering shaft are not separated in the washing state. Maintenance method: When the working position of the clutch pawl is not in place, the square wire clutch spring cannot be loosened, so that both the washing shaft and the dewatering shaft are held tightly by the clutch spring, and the dewatering shaft is held tightly by the brake belt in the washing state. When the clutch pulley rotates clockwise, it cannot drive the pulsator to rotate. When the clutch pulley reverses counterclockwise, it is not only the direction of loosening the clutch spring of the square wire, so that the washing shaft and the dehydration shaft are separated; it is also the direction of tightening the clutch button spring, and the dehydration shaft is still held by the brake belt. The wheels can turn in the opposite direction. Adjust the adjusting screw properly first, so that the clearance between the pawl shift fork and the brake lever is within the normal range. If the pawl shift fork is deformed and damaged, the pawl shift fork can be repaired and corrected. In serious cases, the pawl shift fork needs to be replaced to solve the problem. . The washing machine does not start analysis and maintenance: l. Whether the socket meets the requirements and whether it is in good contact. 2. Whether the door is closed tightly, and whether the micro-delay switch is in good contact. 3. The motor plug wire is in poor contact or the motor is broken. 4. Whether the start button is pressed (the light stays on after the start/pause button is activated), and there is a beep prompt. 5. Whether the faucet is turned on. Maintenance method: 1. Check the power plug and socket to make it in good contact. 2. Check whether the micro-delay switch is in good condition under the power-on state. If it is good, it is a contact problem, and the plug wire should be clamped. 3. Clamp the motor plug or replace the motor. 4. Press the start/pause button again. 5. Open the tap and re-select the program to start. Analysis and maintenance of washing machine not entering water: 1. Improper operation or too low water pressure (less than 0.05Mpa), etc. 2. Whether the door is closed tightly, and whether the micro-delay switch is in good contact. 3. The water inlet solenoid valve is faulty. 4. The water level switch is faulty. Maintenance methods: 1. Recheck: (l) Whether the faucet is open; (2) Whether the water inlet pipe is bent or blocked; (3) Whether the solenoid valve is blocked; (4) Whether the program indication position is accurate; (5) Whether the water pressure is too high Low. 2. Check whether the contact between the door hook and the door lock is good, and adjust if it is not good; check whether the micro-delay switch is in good condition under the power-on state. 3. Power on to check whether the solenoid valve is in good condition and re-tighten it. 4. The water level switch of the mouth blowing should have a clicking sound, if not, replace it. When the program enters the washing state, the motor rotates normally, but the pulsator does not rotate. Analysis and maintenance: The fault mostly occurs in the mechanical transmission part between the motor and the pulsator. Maintenance methods: 1. The fastening screws of the motor pulley, clutch pulley and pulsator are loose, slippery or broken. Just re-tighten or replace the fastening screws; if the square hole of the pulsator is rounded, replace the pulsator. 2. The V-belt slips or falls off. As long as the distance between the motor and the clutch is appropriately increased and some rosin powder is rubbed on the V-belt to increase the friction, it can be solved. If the V-belt is aging and deformed, the V-belt should be replaced. 3. If the parts of the clutch deceleration mechanism are worn or damaged, it is generally necessary to replace the clutch assembly.
Ball Burst Method (ASTM D3787): Steel ball penetration for textiles/films using testers like GT-C02-2.
Hydraulic Method (ISO 13938.1): Fluid pressure on rubber diaphragm for industrial fabrics via GT-C12A.
