Dur­ing the wash­ing process, the wash­ing machine drains water at least twice. The first time — dur­ing the wash­ing itself and again — when rins­ing the washed clothes. There are modes in which the wash­ing machine col­lects and drains water more than twice. If the wash­ing machine con­stant­ly pumps water and drains, then some­thing has hap­pened to it and it must be turned off imme­di­ate­ly and the cause of the mal­func­tion must be found out.

This prob­lem can occur if your wash­ing machine is not con­nect­ed cor­rect­ly or if there is a break­down. This arti­cle will help you find out the rea­son why the wash­ing machine con­stant­ly draws water into the tank and imme­di­ate­ly drains it.

Possible causes of malfunction

If your wash­ing machine con­tin­u­ous­ly draws water, this is a bad sign and this prob­lem needs to be addressed imme­di­ate­ly if you plan to use your appli­ance in the future. There are many rea­sons why a machine stops work­ing prop­er­ly. It is nec­es­sary to under­stand all pos­si­ble rea­sons, and cut­ting off irrel­e­vant ones, to iden­ti­fy the real rea­son that the wash­ing machine does not stop pump­ing water.

Here are the main rea­sons for the inop­er­abil­i­ty of the machine:

  • Mis­takes were made when con­nect­ing the wash­ing machine to the water sup­ply and drainage sys­tem.
  • Dur­ing oper­a­tion, the tank of the wash­ing machine lost its tight­ness and began to leak water.
  • The sen­sor, which deter­mines the water lev­el in the tank, is out of order.
  • The inlet valve that reg­u­lates the water sup­ply has stopped work­ing nor­mal­ly
  • the con­trol unit has ceased to func­tion nor­mal­ly.

washing machine constantly fills with water

If you just bought a car, then the pres­ence of a prob­lem may indi­cate a fac­to­ry defect. Maybe in a new wash­ing machine, there is a defec­tive part, or prob­lems with the elec­tron­ics.

The washer is not connected correctly

If you have just bought a wash­ing machine and are sure that it is in per­fect work­ing order, but for some rea­son it con­stant­ly draws water, it means that the drain hose is most like­ly con­nect­ed incor­rect­ly.

If the con­nec­tion of the wash­ing machine is car­ried out by a non-pro­fes­sion­al who is not famil­iar with the ele­men­tary laws of physics, then the so-called “siphon effect” may appear. This leads to the fact that the used water from the sew­er will begin to flow into the switched off wash­ing machine. And when the wash­ing machine is run­ning, it will pump clean water all the time, which will also con­stant­ly pour into the sew­er.

You will imme­di­ate­ly feel that your water con­sump­tion will increase dra­mat­i­cal­ly, the wash­ing machine will either wash poor­ly or not wash clothes at all.

To fix this prob­lem, it is nec­es­sary to prop­er­ly orga­nize the drain sys­tem by rais­ing the drain hose 50–60 cm from the floor lev­el or installing an anti-siphon valve on the hose. It is prefer­able not to install a siphon valve, which requires peri­od­ic clean­ing, but to prop­er­ly orga­nize the drain sys­tem.

Leaky washing machine tank

If the tank is leak­ing in your wash­ing machine, then it will be imme­di­ate­ly notice­able in the pud­dles on the floor. The elec­tron­ic unit will give a con­stant sig­nal for pump­ing, but the tight­ness of the tank will not allow the machine to work nor­mal­ly and its pump will con­stant­ly sup­ply new water to the leaky tank.

washing machine constantly draws water what to do

Mod­ern machines have spe­cial “aqua-stop” sys­tems that block the sup­ply and dis­charge of water in the event of a leak in the tank. Usu­al­ly in this case, it is nec­es­sary to replace the tank. Weld­ing or braz­ing of mod­ern tanks is often impos­si­ble due to the mate­r­i­al from which they are made.

The pressure switch is out of order


Anoth­er rea­son why the wash­ing machine con­tin­u­ous­ly fills with water is the fail­ure of the water lev­el sen­sor. The water lev­el sen­sor is a device by which the elec­tron­ic unit eval­u­ates how much water is in the tank. If the com­mand from the sen­sor is incor­rect, then the elec­tron­ics con­sid­ers that there is not enough water in the machine and gives the com­mand to fill the tank. This prob­lem is solved by replac­ing the pres­sure switch or repair­ing it. This device has the fol­low­ing prob­lems:

  1. The rub­ber of the mem­brane los­es its tight­ness. Dur­ing oper­a­tion, all rub­ber parts grad­u­al­ly lose their prop­er­ties and require replace­ment.
  2. The sen­sor con­tacts are oxi­dized. They need to be cleaned up. If the con­tacts are severe­ly rust­ed, they must be replaced.
  3. The appear­ance of cracks on the sen­sor tube. In this case, it is nec­es­sary to com­plete­ly change the block. It is very dif­fi­cult to cor­rect such a prob­lem qual­i­ta­tive­ly.

Why does a washing machine fill with water and immediately drain?

It is worth con­sid­er­ing that the pres­sure switch is not a very expen­sive device, even for new mod­ern cars. There­fore, if there are prob­lems with it, the eas­i­est way is to buy a new one and put it in the wash­ing machine.

Inlet valve failure

If the inlet valve in the wash­er has stopped func­tion­ing cor­rect­ly, this may also be the rea­son that the machine is con­stant­ly pour­ing cold water. If the valve has lost its tech­ni­cal char­ac­ter­is­tics, then water will con­tin­u­ous­ly flow into the wash­ing machine. It does­n’t even mat­ter if the machine is on or off. This will great­ly increase the con­sump­tion of cold water. The inlet valve can­not be repaired. You need to pur­chase a new one from the store and install it in the sys­tem.

Control unit failure

If the wash­ing machine con­stant­ly draws water and the rea­son for this is the elec­tron­ic con­trol unit, then it is nec­es­sary to con­sult with a pro­fes­sion­al. Don’t both­er check­ing and repair­ing it your­self. You can per­ma­nent­ly break elec­tron­ics if you do not have the nec­es­sary knowl­edge and skills. If there is a break­down in the con­trol unit, then most often it is not repaired, but a new one is installed.

washing machine fills with water and immediately drains

If your wash­ing machine con­stant­ly pumps water into the tank, then this is a seri­ous break­down in which it is impos­si­ble to use house­hold appli­ances. If you do not fig­ure out in a time­ly man­ner what is caus­ing the incor­rect oper­a­tion, then you can wait until the wash­ing machine fails com­plete­ly, and its repair will become very cost­ly, or even impos­si­ble. There­fore, at the first “call”, imme­di­ate­ly start look­ing for the cause of the break­down and ways to elim­i­nate it.
