Failure 1: The water inlet stops before reaching the set water level.
Analysis and repair: this fault is mainly poor performance of the water pressure switch, so that the air pressure inside the air collection room has not yet reached the prescribed pressure, its contacts will be converted in advance by the state of disconnection for the state of closure and stop the water inlet,
Specific reasons and treatment methods are:
(1) the water pressure switch water level control spring pre-compression is small, as long as you screw in the adjusting screw to increase the water level control Spring pre-compression can be solved if the water level control spring elasticity becomes small or lose elasticity, then replace the water level control spring.
(2) water pressure switch cam groove wear or damage, generally to replace the cam can be solved.
Failure 2
: The water inlet must exceed the set water level by a large amount before the water inlet will stop.
Analysis and repair: This phenomenon shows that the actual water level has reached the required height, the water pressure switch air pressure inside the air collection room still does not reach the required value, only continue to raise the water level, the water pressure switch will act.
Specific reasons and treatment methods are:
(1) water pressure switch air chamber air guide connector blockage or air leakage. As long as the removal of debris at the air-conducting nozzle; or in the air leakage can be sealed with 401 adhesive. If the air guide hose is aging kink or rupture leakage, then to replace the air guide hose.
(2) water pressure switch water level control spring pre-compression is too large. As long as the adjusting screw out some, reduce the water level control spring pre-compression can be.
(3) water pressure switch in the reversing top rod and transmission components deformed or damaged. Can be repaired and corrected to solve the problem, in serious cases to replace the water pressure switch
Failure 3: program into the washing state, the motor rotation is normal, but the wheel does not turn.
Analysis and repair: the fault occurs in the motor to the mechanical transmission between the part of the wheel.
Specific causes and treatments are:
(1) motor pulley, clutch pulley and wave wheel fastening screws loose, slippery wire or broken. Just retighten or replace the fastening screws; if the square hole of the wave wheel rolls round, replace the wave wheel.
(2) Triangle belt slipping or fall off. As long as the appropriate motor and clutch distance and in the triangle belt rub some rosin powder to increase friction can be solved. If the belt is aging and deformed, then replace the belt.
(3) the clutch reducer parts wear or damage, generally have to replace the clutch assembly.
Failure four: when washing, the dewatering bucket heel turn.
Analysis and repair: dehydration bucket with the rotation of two cases, one is the dehydration bucket clockwise direction with the rotation; the second is the dehydration bucket counterclockwise direction with the rotation.
Dewatering bucket clockwise with the specific causes and treatment are:
(1) brake belt loose, so that the brake belt on the dehydration shaft braking torque decreases, as long as the re-installation of the brake belt can be.
(2) The brake belt is seriously worn or damaged. By rotating the adjusting screw, the pawl position can be adjusted appropriately to increase the braking torque of the brake band on the dewatering shaft, and the brake band should be replaced in serious cases.
Dewatering bucket counterclockwise to follow the specific causes and treatment are:
(1) clutch torsion spring off, broken or torsion spring and dewatering shaft with too loose and slippery, so that the torsion spring loss of stop function. Just reload the torsion spring or replace the torsion spring can be, serious cases to replace the reducer.
(2) clutch brake band loose, worn or broken. Just retighten or replace the brake band.
(3) Clutch brake spring or fork spring is too soft or broken. Just replace the clutch brake spring or fork spring to solve the problem.
Failure 5: when washing, the motor is normal in forward and reverse operation, while the wave wheel can only one-way reversal, can not be forward.
Analysis and repair: this fault is the clutch pawl fork deformation or adjusting screw screwed too deep, so that the pawl working position can not be in place, resulting in the washing shaft and the dehydration shaft in the state of washing is not separated.
Because the clutch pawl working position is not in place, the square wire clutch spring can not be dialed loose, so that the washing shaft and the dehydration shaft are held by the clutch spring, and the dehydration shaft in the state of washing is held by the brake belt. When the clutch pulley rotates positively in the clockwise direction, the pulley cannot be driven to rotate. When the clutch pulley counterclockwise direction reversal, both is the clutch square silk clutch spring spinning loose direction, so that the washing shaft and dehydration shaft separation; and is the clutch knob spring spinning tight direction, dehydration shaft is still being held by the brake belt, at this time, the wave wheel can be rotated in the opposite direction.
First properly adjust the adjustment screw, so that the pawl fork and brake lever clearance within the normal range, if the pawl fork deformation damage, the pawl fork can be repaired and corrected, serious pawl fork to be replaced to solve the problem.
Failure six: slow drainage.
Analysis and repair: this fault is generally not fully open the drain valve or drain pipe is not smooth.
Specific causes and treatment methods are:
(1) drainage valve clogged with debris or drainage hose bending deformation. As long as the removal of debris in the drain valve or replace the drain hose can be solved. (2) drainage lever and rubber valve gap becomes large, as long as the appropriate adjustment of the drainage lever and rubber valve gap can be.
(3) drain valve spring is too long or lose elasticity. Just replace the inner spring.
(4) drain solenoid valve moving core damping or suction becomes small. Clear the solenoid corrosion dirt or replace the drain solenoid valve.
Fault seven: drainage is not clean.
Analysis and repair: this fault is generally poor performance of the water pressure switch or air pipeline leakage, so that the air pressure inside the air collection room becomes smaller,
When the water level in the water bucket has not yet dropped to the required position, the water pressure switch contacts will be early action, so that the total drainage time is shortened, resulting in
drainage is not clean failure. Just try to find the air leak in the air line and seal it with 401 adhesive. If the water pressure switch is damaged, replace it.
Fault 8: After the end of dehydration, the braking time is too long.
Analysis and repair: the fault is that the brake belt can not hold the dehydration shaft brake wheel, so that the brake friction is reduced.
Specific causes and treatments are:
(1) the clutch on the installation of the brake band skewed, lining wear or fastening screws loose. Simply reinstall or replace the brake band.
(2) The brake spring is loose, broken or has lost its elasticity. Simply reinstall or replace the brake spring.
(3) The brake lever is pinched by the pawl fork and cannot be returned, so that the brake band cannot hold the dehydrated axle brake wheel tight. As long as the pawl fork position adjustment, repair or replacement of the fork can be.
(4) electromagnet moving core is blocked by debris can not be fully extended, so that the brake lever can not be restored to the original position. As long as the removal of the electromagnet on the core of the corrosion of dirt or repair the electromagnet can be replaced.
Fault nine: dehydration, dehydration bucket has a large vibration noise.
Analysis and repair: the specific causes of vibration noise caused by the dehydration bucket and processing methods are:
(1) between the dehydration bucket and washing drum debris. Just remove the debris.
(2) the dehydration bucket balance ring rupture or leakage, so that the dehydration bucket rotation loss of balance. Just replace the balance ring can be solved.
(3) dehydration bucket flange fastening screws loose or broken. Just tighten or replace the flange can be.
(4) Dewatering bearing is severely worn or loose. Simply tighten or replace the dewatering bearing.
(5) Dewatering bearing is severely worn or loose.
