First of all, when the washing machine can't put out water, you need to check whether the water supply is normal. Follow these steps::
Confirm that the faucet is open and that the water supply pipe is not blocked.
Check the connection of the water supply pipe for loose or leaking water, and the sealing ring needs to be tightened or replaced.
Check whether the water pressure is normal, you can turn on other water sources for detection.
If the water supply is normal, the next thing you need to check is that the water valve inside the washing machine is working properly
Disconnect the power to the washing machine.
Unscrew the faucet part of the water inlet pipe that connects to the washing machine and remove the water valve with a wrench.
Check the water valve for blockages or damage, and if so, need to be cleaned or replaced.
If the water valve is normal, you can use a multimeter to test the resistance to ensure that the circuit is normal.
If both the water supply and the water valve are normal, there may be a problem with the pump inside the washing machine:
Disconnect the power to the washing machine.
To open the lid of the washing machine, it is usually necessary to unscrew the screws or press the buckle.
Locate the pump, check for blockages or foreign objects, and the pump needs to be cleaned or replaced.
Check whether the circuit of the water pump is normal, you can use a multimeter to test it.
If the above steps do not solve the problem, it is recommended to seek a professional maintenance master for overhaul and repair.
Water supply problems: faucets not open, clogged water supply pipes, insufficient water pressure, etc.
Water valve problems: clogged or damaged water valves, faulty circuits, etc.
Pump Problems: Clogged, damaged, or electrical problems with the pump.
Other issues: control panel failure, sensor failure, etc.
These are only common causes, and specific problems need to be diagnosed and dealt with on a case-by-case basis.
