How to Repair a Washing Machine

The whole machine does not work

First, observe whether the power indicator light is on and whether the fuse is fused. Check the power rectifier filter and voltage transformer circuits if the power indicator light is on. If the power indicator light is not on, the fault occurs in the panel control circuit part. If the fuse is blown, the load part has a short-circuit fault. You need to check the washing motor, dehydration motor, drying heat-generating components, etc.

Abnormal water inlet

No water inlet

First, check if there is a problem with the power supply. If regular, then check whether the fuse is fused. If it is not connected, check whether the water pressure and water inlet pipe are normal. If there is no abnormality, check whether the water inlet valve filter is blocked. If normal, the water inlet valve coil is damaged.

The water intake does not reach the set water level when the water intake stops

First, check whether the spring force of the water level control becomes smaller or loses elasticity. If so, replace the water level control spring; if not, the groove on the water pressure switch cam is worn or damaged.

The water intake must exceed the set water level by more before the water intake stops

First, check whether the water pressure switch air guide connection is blocked or leaking. If yes, clear the debris at the air guide nozzle, or seal the air leak with 401 adhesives; if not, check whether the air guide hose is aged and kinked or broken and leaking. If not, check whether the water pressure switch water level control spring pre-compression is too large. If yes, reduce the pre-compression amount of the water level control event. If not, the water pressure switch is deformed or damaged in the reversing top rod and transmission parts.

More than the water inlet

More than water intake is usually the water inlet valve, and its components to control the water inlet valve are faulty.

Drainage abnormal

Slow drainage speed

First, check if the drain valve is clogged with debris or if the drain hose is bent. If yes, remove the trash in the drain valve or replace the drain hose; if not, check whether the drainage tie rod and rubber valve clearance are too large. If yes, adjust the gap between the drainage lever and the rubber valve appropriately; if not, check whether the spring inside is too long or loses elasticity. If yes, replace the innerspring; if not, the drain solenoid valve dynamic iron core damping is too large, or the suction force becomes small.

No drainage

First, check whether the drain pipe is down. If yes, prevent whether the drain pipe is submerged in water or the end is sealed in the sewer; if not, check whether the rubber seal inside the drain valve seat is blocked by dirt. If not, check if the drain is more than 15cm above the ground. If not, the extension drain is too long or too thin in diameter.

Drainage is not clean

First of all, check whether the performance of the water pressure switch is bad or whether there is air leakage in the airline. So that the air pressure inside the air collection chamber becomes small. When the water level in the bucket has not yet fallen to the specified position, the water pressure switch contact will act in advance. So the total drainage time is shortened, resulting in unclean drainage. If the water pressure switch is damaged, replace the water pressure switch; if the airline leakage, find the airline leakage and seal it with 401 rubber.

Abnormal washing

No washing

First, check whether the power is out or the fuse is fused. If not, check whether the power supply voltage is too low. If not, check whether the water intake exceeds the required water level (if the water intake does not reach the set level, the washing machine will not work). If not, check if “appointment” washing is set (the washer will not start working until the appointment time is selected). If not, check if the washing control circuit is defective. If not, check if there are damaged components in the electrical part of the wash. If not, the washing machine is stuck.

When washing, the bucket is rotating

First, identify whether the bucket is rotating clockwise or counterclockwise. If the bucket rotates clockwise. Then check whether the brake belt is loose and whether the brake belt is worn or damaged. If the bucket turns counterclockwise, check whether the clutch torsion spring is off or broken and whether the torsion spring is loose with the dewatering shaft and slipping. And whether the clutch brake belt is loose, worn, or damaged. And whether the clutch brake spring or fork spring is too soft or broken.

When washing, the motor usually runs in forward and reverse directions. Still, the wave wheel can only change in one order but not in the forward movement.

First, check whether the clutch pawl fork is deformed or the adjusting screw is screwed in too deep. So that the pawl working position cannot be in place, resulting in the washing axis and the dewatering axis not being separated in the washing state. If the pawl fork is deformed and damaged, repair and correct the pawl fork or replace the pawl fork. If the screw is screwed in too deep, adjust the adjusting screw appropriately so that the pawl fork and brake lever clearance is within the normal range.

Abnormal dehydration

No dewatering

First, check whether the door cover is closed. If yes, check whether the clothes are placed too much; if not, check whether the washing machine is set smoothly. If yes, check if the motor drive belt is too loose; if not, check if the spinning motor or starting capacitor is damaged. If not, then the spinning motor reduction clutch is holding the shaft.

Loud noise when dewatering

First, check whether there is any debris between the dewatering and washing drum. If there is, the waste can be removed; if not, check whether the balance ring of the dehydration bucket is broken or leaking. So that the dehydration bucket loses its balance when rotating. If yes, replace the balance ring; if not, then check whether the flange fastening screw of the bucket is loose or broken. If yes, tighten or replace the flange; if not, the dewatering bearing is seriously worn or loose.

Water leakage

First, check whether there is a crack in the washing bucket. If not, check if the wash shaft oil seal is terrible; if not, check if the front sight hole seal is aging. If not, the drain valve is not sealed tightly.

Leakage

First, determine whether it is an induction leak or a line leak. If it is induction leakage, the line or insulator insulation performance is reduced. If it is line leakage, it means that the line is broken off a lap or motor insulation is poor. Inspection should be used to check the local inspection method segmentation, such as the separation of a part, the fault disappears, meaning the removal of the amount of the leakage.

Buzzer does not alarm

First, determine whether the buzzer itself is damaged. If yes, replace the buzzer; check the buzzer driver circuit and the control circuit for problems.

The motor usually rotates, but the wave wheel does not turn

First, check whether the fastening screws of the motor drive wheel, clutch pulley, and pulley are loose, slippery, or broken. If not, check whether the triangle drive belt is slipping or falling off. If not, the clutch reduction mechanism parts are worn or damaged, and the clutch assembly usually needs to be replaced.

After the end of dehydration, the braking time is too long

First, check if the brake belt on the clutch is installed crooked, the lining is worn, or the fastening screw is loose. If so, reinstall or replace the brake band; if not, check to see if the brake spring is loose or broken. If yes, reinstall or replace the brake spring; if not, check whether the brake lever is detent fork top can not return so that the brake belt can not be held tight to the dehydration shaft brake wheel.

If so, as long as the pawl fork is in a position to adjust, repair, or replace the division. If not, it means that the electromagnet dynamic core is blocked by debris.

And can not be fully extended so that the brake lever can not return to the original position.
