If the LG washing machine does not fill with water, it will not be possible to start the scheduled wash. You will have to forget about dirty things and start diagnosing the machine, since a “dry” drum can signal either a minor failure or large-scale problems. Our instruction article will help you understand what led to the trouble, valve, pressure switch, UBL or heating element.
Several reasons can lead to problems with water intake: from a simple blockage in the hose to a failed control board. What makes the search easier is that some problems appear in LG machines more often than others. Among them are the following malfunctions:
Inoperative water supply valve. A clear sign of this breakdown is that the powder in the tray is not washed off, since first, water must flow into the powder receptacle. To confirm your guess, you should check the part: apply 220 Volts to the valve and listen. If you hear a click, it means there is a short circuit, and everything is fine. In this case, the drum will begin to fill, and the problem will be resolved. Otherwise, replacement will be required. The valves ring in pairs, and if there is no click, they are replaced using a slotted screwdriver.
Clogged water supply mesh. When clogged, the machine tries to fill the tank for a long time, making an unpleasant buzzing sound.
Non-functioning pressure switch. If the level sensor incorrectly sends signals to the control board, for example, it detects a full tank, then the intake will not start. Therefore, we remove the top cover, look for a round part with a tube going down the machine and disconnect the latter from the “box.” Then we blow into the tube and try to hear 1-2 clicks. It is likely that due to prolonged stagnation, the hose has become clogged with cobwebs, dust, or fabric fibres, which will disappear after blowing out.
Problems with the control board. Burnt out resistors on the control unit of the washing machine often interfere with the full flow of the fence. To correct the situation, you need to replace them or purchase a new module. But we strongly do not recommend trying to solve a problem with electronics on your own - such work should only be carried out by a service center employee.
It is also worth checking the wire going from the pressure switch to the tank. The fact is that it often suffers from premature wear and begins to leak air, introducing an imbalance in the operation of the level sensor. The correct functioning of the UBL is also important, since the system, receiving erroneous signals, may consider the door open and not start washing with water.
Another reason is a burnt-out pump. If the board does not receive a command from the pump that it is ready to drain water, then the machine does not start the cycle and, in fact, the intake. It is unlikely that you will be able to cope with the malfunction on your own since it requires a long and serious repair. It is better to immediately contact professionals.
Initial actions
If you notice problems with the flow of water into the tank, you need to act. If the car was purchased less than a year ago and it is still under warranty, then there is only one answer to the question what to do - contact the service center with a receipt and a warranty card. You should not open the case yourself and try to fix the problem.
Older machine owners will have to go a different route and pay for repairs out of their own pockets. Doing it yourself will be cheaper but will require more time and effort. First, you need to establish the “sore spot” of the washing machine, so we sequentially check the above-mentioned parts of the system, moving from simple to complex.
At the start, if you notice a missing set and a barely audible buzzing sound, you should do the following:
If after successfully carried out first aid there is no result, pay attention to the filler hose filter. More precisely, on the filter installed in it - a fine metal mesh. It often becomes clogged with scale and small debris.
Next comes the coarse filter. As a rule, this mesh is placed after the tap and suffers from scale. But here the cleaning scheme is different: we take two wrenches and, holding the joint with one, unscrew the bolt with the second. First you need to place a container under the pipe and release water with strong pressure. The flow will clean out the dirt, and all that remains is to return the nut to its place.
Often, water does not flow into the tank due to problems with the valves. The problem is that these parts cannot be tightened or blown out, so they will need to be replaced.
A faulty heating element also causes the machine to shut down for water intake. If the scale layer is not removed manually or the multimeter indicates a breakdown, the heater will have to be replaced. We will provide instructions now.
If the check shows that the heating element and valves are in perfect order, but water is still poorly poured into the tank, we pay attention to the machine door. The hatch blocking device or UBL does not work, and the control board does not send a command to set the drum. Therefore, we disconnect the machine from communications, and begin to test the locking mechanism, “ring with a multimeter” and clean the contacts.
