A great helper in the kitchen is a dish­wash­er. She helps to quick­ly wash the plates and cut­lery after a fam­i­ly din­ner. The prin­ci­ple of their oper­a­tion and design fea­tures are sim­i­lar to wash­ing units. They are con­nect­ed only to the cold water sup­ply sys­tem, and the water is heat­ed by them­selves. As soon as the desired tem­per­a­ture is reached, the select­ed modes start. If the dish­wash­er does not heat water, then it indi­cates the pres­ence of break­downs. It is nec­es­sary to take mea­sures to restore the equip­ment.

Dishwasher does not heat water — causes of malfunctions

If the water remains cold, then the machine sim­ply will not be able to wash the dish­es well. More­over, in some cas­es, the wash­ing process itself sim­ply does not start, since the con­trol sys­tem does not receive a sig­nal from the sen­sors.

Caus­es of mal­func­tion­ing dish­wash­ers:

  • the heat­ing ele­ment itself (TEN) has failed;
  • the ther­mo­stat is not adjust­ing the tem­per­a­ture cor­rect­ly;
  • var­i­ous ele­ments of the con­trol sys­tem do not work cor­rect­ly.

This is a fair­ly com­mon prob­lem faced by ser­vice cen­ter spe­cial­ists. There are not many com­mon rea­sons lead­ing to such a defect. Usu­al­ly this is due either to mal­func­tions of sen­sors and ther­mostats, or to a break­down of the heat­ing ele­ment. Over time, it can sim­ply burn out or become cov­ered with scale. Man­u­fac­tur­ers them­selves tell why this hap­pens with the dish­wash­er and what to do in this case.

The dishwasher does not heat up water — diagnosing problems

Despite the fact that prob­lem solv­ing tech­niques have long been devel­oped, it is still rec­om­mend­ed to con­duct a full diag­no­sis and test var­i­ous options. In rare cas­es, it hap­pens that seem­ing­ly third-par­ty break­downs actu­al­ly lead to the fail­ure of ther­mostats and heat­ing ele­ments. Why this hap­pens, only experts after a thor­ough exam­i­na­tion can say.

dishwasher diagnostics

There are a few oth­er options worth check­ing out:

  • equip­ment may be con­nect­ed incor­rect­ly or with vio­la­tions;
  • there is a block­age in the water pipes or fil­ters, so the water sim­ply does not fill up;
  • the dish­wash­ing mode is incor­rect­ly select­ed or the set­tings are incor­rect­ly set;
  • the pres­sure sen­sor has failed.

Dur­ing the wash­ing process, the water inside cir­cu­lates, and this process is con­trolled by a pres­sure sen­sor. If it is faulty, then the cir­cu­la­tion does not stop, and the water sim­ply does not have time to heat up to the desired tem­per­a­ture.

The dishwasher does not heat the water — what to do?

Often you can deter­mine the rea­sons your­self. At the very least, this will be able to help spe­cial­ists who will already be direct­ly involved in the repair and explain why the equip­ment failed.

does not heat water

For diag­nos­tics, you must per­form the fol­low­ing steps:

  • check if the equip­ment is con­nect­ed cor­rect­ly and which modes are select­ed;
  • see if water enters the tank;
  • does the machine turn on in nor­mal wash­ing mode;
  • check to see if water is stag­nat­ing inside the tank.

In nor­mal oper­a­tion, water must con­stant­ly cir­cu­late between the tank and the addi­tion­al tank. In the process of this, the heat­ing ele­ment main­tains the desired tem­per­a­ture. If the water stops cir­cu­lat­ing, then this indi­cates prob­lems with the pres­sure sen­sor, or with the fil­ters. Check if the debris fil­ter is clogged and clean if nec­es­sary.

If, dur­ing a nor­mal inspec­tion, the water cir­cu­lates nor­mal­ly and does not stag­nate exces­sive­ly inside the machine, and also drains at the end of the wash, then the heat­ing prob­lem is asso­ci­at­ed with more seri­ous break­downs. In this sit­u­a­tion, the tem­per­a­ture sen­sor and con­trol mod­ule should be checked. The prob­lem occurs quite often, so usu­al­ly you just need to replace it.
