Analysis and maintenance: The fault occurs in the mechanical transmission parts between the motor and the wave wheel. The specific reasons and treatment methods are:

(1) The fastening screws of the motor pulley, clutch pulley and wave wheel are loose, and the wires are slipped or broken. Just re-tighten or replace the fastening screws; If the wheel square hole is round, the wheel should be replaced.

(2) Triangle belt slip or fall off. As long as the distance between the motor and the clutch is properly adjusted and some rosin powder is rubbed on the triangle belt to increase the friction can be solved. If the triangle belt is aging and deformed, the triangle belt should be replaced.

(3) The parts of the clutch deceleration mechanism are worn or damaged, and the clutch should generally be replaced.

Analysis and maintenance: there are two cases: one is to turn the bucket clockwise; The second is to take off the bucket and turn it counterclockwise.

The specific reasons and treatment methods for the clockwise rotation of the bucket are:

(1) The brake belt is loose, so that the braking torque of the brake belt on the dehydration shaft is reduced, as long as the brake belt is re-installed.

(2) The brake belt is seriously worn or damaged. By rotating the adjusting screw, the position of the pawl can be properly adjusted to increase the braking torque of the brake belt on the dehydration shaft, and the brake belt should be replaced in serious cases.

The specific reasons and treatment methods for counterclockwise rotation of the bucket are:

(1) The clutch torsion spring falls off, breaks, or the torsion spring is too loose with the dehydration shaft and slips, so that the torsion spring loses the reverse function. As long as the torsion spring is re-installed or replaced, the reducer should be replaced in serious cases.

(2) clutch brake belt loose, worn or broken. Simply retighten or replace the brake belt.

Analysis and maintenance: This fault is caused by the deformation of the clutch pawl fork or the adjustment screw is too deep, so that the working position of the pawl can not be in place, resulting in the washing shaft and the dehydration shaft are not separated in the washing state.

When the working position of the clutch pawl is not in place, the square wire clutch spring can not be loosened, so that the washing shaft and the dehydration shaft are tightly held by the clutch spring, and the dehydration shaft is tightly held by the brake belt in the washing state. When the clutch pulley is turning clockwise, it cannot drive the wave wheel to rotate. When the clutch pulley is reversed counterclockwise, the direction of the clutch wire clutch spring is loosened, so that the washing shaft and the dewatering shaft are separated. The clutch button spring is tightened in the square direction, the dewatering shaft is still held tightly by the brake belt, and the wave wheel can be turned in reverse at this time.

First adjust the adjusting screw properly, so that the gap between the pawl fork and the brake rod is within the normal range. If the pawl fork is deformed and damaged, the pawl fork can be repaired and corrected. In serious cases, the pawl fork should be replaced to solve the problem.

Analysis and maintenance: This fault is generally caused by the drainage valve is not fully opened or the drainage pipe is not smooth. The specific reasons and treatment methods are:

(1) There is debris blocked in the drainage valve or the drainage hose is bent and deformed. Just remove the debris in the drainage valve or replace the drainage hose to solve the problem.

(2) The gap between the drainage rod and the rubber valve becomes larger, as long as the gap between the drainage rod and the rubber valve is appropriately adjusted.

(3) The internal spring of the drainage valve is too long or loses elasticity. Just replace the inner spring.

(4) The drainage solenoid valve moving core damping is too large or the suction becomes small. Remove the corroded dirt in the electromagnet or replace the drainage solenoid valve.

Analysis and maintenance: This fault is generally poor performance of the water pressure switch or air leakage in the air pipeline, so that the air pressure in the gas collection room becomes smaller, when the water level in the bucket has not fallen to the specified position, the water pressure switch contact will act in advance, so that the total drainage time is shortened, resulting in unclean drainage. Just try to find the air line leak and seal it with 401 glue. If the water pressure switch is damaged, replace it.

Analysis and maintenance: The fault is caused by the brake belt can not hold the dewatering shaft brake wheel tightly, so that the brake friction is reduced. The specific reasons and treatment methods are:

(1) The brake belt on the clutch is mounted crooked, the lining is worn or the fastening screw is loose. Simply reinstall or replace the brake belt.

(2) The brake spring loosens, breaks or loses elasticity. Just reinstall or replace the brake spring.

(3) The brake rod cannot be returned to position by the pawl fork, so that the brake belt cannot hold the dewatering shaft brake wheel tightly. Adjust, repair, or replace the fork position of the pawl.

(4) The electromagnet moving core is blocked by debris and cannot be fully extended, so that the brake rod cannot be restored to its original position. Just remove the rust dirt on the electromagnet moving core or replace the electromagnet.

Analysis and maintenance: The specific causes and treatment methods of the vibration and noise of the bucket are:

(1) There is debris between the bucket and the washing bucket. Just remove the clutter.

(2) The balance ring of the bucket is broken or leaking, so that the balance of the bucket is lost when it rotates. Just replace the balance ring.

(3) The tightening screw of the bucket flange is loose or broken. Just tighten or replace the flanges.

(4) The dehydrated bearing is seriously worn or loose. Simply tighten or replace the dehydrated bearing.

1. Check the power cord: First of all, check whether the power cord of the dryer has been plugged in, whether it is loose or damaged. If there is no problem with the power cord, check that the power outlet is energized.

2. Check the fuse: If the dryer can not be turned on, you can also check whether the fuse is blown. If the fuse is blown, a new fuse needs to be replaced.

3. Check the control panel: If the above two items are OK, then you need to check whether the control panel is normal. If there is a problem, contact the maintenance personnel to replace it.
