Why a washing machine does not get water

The reasons why a washing machine does not draw water is much more than when it refuses to drain. This is unbelievable because the only mechanism involved is the intake valve. However, the control circuit is such that the process involves a lot of sensors. Therefore, the overall reliability decreases, the causes of failures are spread out by grouping. Today we consider the perpetrators of the refusal of water intake.

Preparation for washing

How a washing machine draws water

The intake valve is responsible for the water collection. Water comes in under the pressure of the riser. Manufacturers write that washing machines are designed for the established conditions. In the villages, people suffer and ask: how to connect household appliances in the absence of a central water supply system.

Note. Already previously answered the question how to connect the washing machine without pressure. Look through the section of the site.

At the entrance to the valve is a plastic mesh, it needs to be periodically cleaned. Begin the intake of water in charge:

  1. Electronic Brain( or timer-programmer).
  2. Water level sensor.

The central unit always knows which program should start, therefore it allows or denies water intake. Without a level sensor, the process is certainly impossible. In a full tank to collect water is impossible. Level control is the responsibility of the sensor. Curious cases occur when the rinse is normal and the wash does not start: the washing machine does not get enough water.

Double inlet valve

The inlet valve is often double, and in addition, selected washing machines operate from two hoses - cold and hot - in order not to waste water. If the first step of the cycle comes from one riser, the second - from another. The inlet valve has on each path through the membrane, each with a separate control coil. There is a reason for interruptions.

Rough filter and

riser According to the technology of laying water pipes in the apartment it is necessary to place a coarse filter from the riser. If earlier it was mounted exclusively on cold water, now on hot. Regardless of the type of washing machine, check two things:

  • Is the stand valve open? In ball valves, the position of the handle is assumed to be made parallel to the pipe in the open state.
  • The coarse filter is sometimes clogged. Mostly - the only apartment, check whether there is water in the faucet( necessary, hot or cold).If necessary, clean the standpipe overlap, unscrew the bolt with a key, take out the mesh, wash, and assemble in the reverse order.

If everything is in order, turn off the ball valve and approach the washing machine.

Self-leveling hose and fine filter of the washing machine

The self-leveling hose is screwed exclusively by hand. Do not grab the pliers or the key. Turns away in the same way. Rubber gasket will not allow water to leak. With the end turned, hold the hose over the tub. Carefully open the ball valve - a strong jet is expected. If everything is in order, return the valve to its original position and hold the pliers with thin noses.

Inlet hose and fine filter

Carefully remove the fine filter from the washing machine. It is located right behind the hose, in front of the intake valve. The fine filter is similar to a thimble, the outer edge is topped with a comb. For the ledge and grab. When reinstalling do not confuse the outer side, it is convex with a comb. Mess up - it will be difficult to pull out to put correctly.

The filter is rinsed under running water. If the part is clean, the reason is different. We'll have to disassemble the washing machine.

The inlet valve of the washing machine

The inlet valve of the washing machine can be single, double or triple. Accordingly, individual modes are able to draw water, while others will not. It is necessary to check each path separately. For this washing machine is disassembled. The first is often removed the top cover. Nothing more is needed - the inlet valve is located at the top on the back wall.

Inside there are coils according to the number of channels, each with a core opens and cuts off the course of the water. At the common entrance there is a gearbox to reduce the pressure. It's just a rubber washer, it is permissible to remove and rinse, if you can see that dirt has accumulated inside. Be careful! If dirt gets blocked in the inner membrane, the valve will begin to constantly poison the water. In the latter case, repair the part is extremely difficult. Have to buy a new one.

Now on the device. Each coil includes a core-rod resting on the membrane, in the center of which a hole is made. In normal condition, the return spring keeps the system closed. When current is applied to the coil, the stem is raised, giving freedom to the water. This is a fence for any step of the cycle. A voltage of 220 V is applied to the coils, by disconnecting the terminals, it is possible to check each turn.

Caution! Observe safety precautions when working with high voltages.

Pressostat and timer washing machine

The authors find it difficult to name the control center of the washing machine. In early models, this is a programmer-timer that counts down the seconds and consequently closes and terminates a multitude of contacts. As a result, it is logical to call the part a brain, sending impulses. In later models of care takes electronics. Evaluates the course of the program, the data of the pressostat. If the described option is incorrect, incorrect, it is easy to notice that the washing machine does not get water, that's all.

If the inlet valve has already been tested, it seems to make no sense to measure the voltage at the input terminals of the valve. However, a trivial breakage is possible. Measure the signal from the electronic unit. Use the wire color to find the connector you want. Additionally, call the tester to ensure correctness. Previously it is useful to check the pressure switch, in other words, the level sensor.

Pressostat and timer of the washing machine

The subject is similar to a washer with many holes. Pressostat happens to different number of levels, two, three. Accordingly, the relay clicks when the pressure rises differs identical quantity. Inside there is an equal shoulder lever, pressing on groups of contacts with different pressing forces. Due to this, sequential operation occurs. Shoulders are spaced in a circle and with an equal angle. The pressure is the same.

Consider how the process takes place in the case of three levels. The arms of the lever are scattered in a circle with a spread of 120 degrees. Groups of contacts lie parallel to each other or along a circle. At the initial moment, each spring has the same effect when water begins to collect. Soon the weakest spring does not hold up, the first group of contacts is closed. One shoulder goes down.

As the pressure rises further, the second spring does not withstand, already two arms go down. The working chamber of the pressure switch is sealed, it can be disassembled, but it cannot be reassembled.

The pressure sensor is located at the top of the washing machine and is connected to the measuring chamber of the tank through a hose( sometimes a tube).And the water does not get to the pressostat: inside there is air, which shrinks as the level rises. Relay will work accordingly. By the way, the pressure switch needs to be checked when the washing machine gets enough water. This indirectly indicates that electronic logic is not able to properly assess the situation.

If the measures listed did not help to understand why the washing machine does not draw water, the electronic module probably became the cause of the malfunction. This is a complex chipset that is difficult for an ordinary inhabitant to understand; not every service center is taken to repair. The parts described by the authors, in contrast to the electronic board, are not too expensive. It is permissible to wind the coil on the inlet valve with one's own hand or remove the same from another part. Russian radio amateurs will quickly understand what to do.

If the washing machine is slowly drawing water, the filter is probably clogged. Sometimes it's in the riser. It is permissible to try to remove the gearbox from the intake valve. The step will help those who live in the houses - we bring the advice first to runet, notice!
