Do-it-yourself dishwasher repair based on the cause of the problem


The dish­wash­er pro­vides our life with com­fort, but there are often sit­u­a­tions when the device refus­es to work or does it with reduced effi­cien­cy. In this case, if there is no time to wait for the mas­ter, you can try to repair the dish­wash­er with your own hands.

Dishwasher device

To deter­mine why the device has become unus­able, you must first under­stand its device:

  2. dis­penser;
  3. Air path of the dry­ing sys­tem;
  4. Upper bas­ket;
  5. Low­er bas­ket;

  10. Fil­ter.

Primary analysis for various problems

Before start­ing repairs, an ini­tial inspec­tion should be car­ried out to iden­ti­fy the cause of the break­down. Remem­ber that if this can­not be done, then it is bet­ter to refuse self-repair and leave the mat­ter to a spe­cial­ist. So, here are the parts of the device that need to be ana­lyzed:

Noise during machine operation

If it is unnat­ur­al and tap­ping is heard, then wash­ing must be urgent­ly stopped. First of all, we assess the sit­u­a­tion visu­al­ly: are sharp objects inside the impellers or the door of the deter­gent tray inter­fer­ing? If this option is pos­si­ble, then pull them out or shift them to a more con­ve­nient posi­tion and repeat the cycle. It can also knock loose dish­es.

Both options did not fit, which means that your prob­lem is more seri­ous and you will need to repair the dish­wash­er your­self. Knock­ing can occur if the impeller bear­ing is dam­aged. Rotate them by hand to check if there is a knock. If it is clear­ly audi­ble, the bear­ing needs to be replaced.

Impeller bearing

The prob­lem may also be in the bear­ing of the drain or main pump. Find­ing it is easy. The first knocks at the end of the wash, and the sec­ond — through­out the work.

Problems of the water circulation system

Hoses and fit­tings should be checked for accu­mu­la­tion of food debris. This can be done by first dis­con­nect­ing the machine from the pow­er sup­ply.

Water circulation system

Lumps of waste must be removed and the wash restart­ed. If the prob­lem per­sists, then you need to check the hoses and pipes for integri­ty. If there is dam­age, then they must be replaced with new ones. If the fas­ten­ers are loos­ened, tight­en them with the keys.

Problems when turning on

If the device does not turn on, then this may be due to the fol­low­ing rea­sons:

  • Wash­ing will not start if no water enters. The point here may be both in the machine itself and in your crane. If the faucet is not clogged and water is not flow­ing, then check the hose that goes to the device. To do this, you need to dis­con­nect it, sub­sti­tute a con­tain­er under it and turn on the water. If the water does not come out, then the hose is clogged and needs to be cleaned and rinsed well.
  • The wash cycle does not start if the door is not closed prop­er­ly. In this case, turn off the device, open and close the door again, and restart after wash­ing.
  • The last and most dif­fi­cult prob­lem may lie in the pro­gram­mer. With such a break­down, do-it-your­self repair is in no way pos­si­ble — you will have to con­tact the work­shop.

Device switching scheme

When the pump failed

The pump is locat­ed at the bot­tom of the tank or reser­voir. First of all, exam­ine it from the out­side: are there any cracks or scuffs on it. Also check the fas­ten­ing. When every­thing is in order with the mount, the pump must be replaced with a new one.


To do this, unfas­ten the old part from the bot­tom and install a new one. It must be pur­chased in advance in a spe­cial store, accord­ing to the instruc­tions attached to the device.

Other problems

If the machine is run­ning, but the water still does not enter, the inlet valve is most like­ly bro­ken. In such a sit­u­a­tion, it will have to be replaced with a new one. Worn-out seals and pumps are changed in accor­dance with the rec­om­men­da­tions giv­en in the instruc­tions for each machine.

If the machine sud­den­ly stops work­ing dur­ing a cycle, then the first thing to do is check the clean­ing fil­ters. If they are in good con­di­tion and not clogged, then the work­ing pump may break. It could also be the ther­mo­stat on the heat­ing ele­ment. In this case, the heat­ing ele­ment needs to be replaced. How to do this, you will learn fur­ther.

Con­sul­tants from the ser­vice cen­ter can help you iden­ti­fy the prob­lem. In the same place, they can tell you how to prop­er­ly fix this or that mal­func­tion or offer the ser­vices of a spe­cial­ist.

Changing the heating element

Before repair­ing the dish­wash­er when chang­ing the heat­ing ele­ment, you will need to col­lect all the tools nec­es­sary for this: a new part, a set of keys and instruc­tions for the device.

Heating element

Fol­low this algo­rithm exact­ly:

  1. We take out all the trays for dish­es so that they do not cre­ate prob­lems dur­ing work.
  2. We turn off the device from the net­work and unscrew all the hoses.
  3. Remove the sprin­kler, which is locat­ed at the bot­tom of the device, gen­tly pulling it up.
  4. Next to the sprin­kler is a fil­ter — it looks like a plas­tic cup. The fil­ter will also need to be removed.
  5. We remove the stain­less steel mesh.
  6. We unscrew the screws that hold the pipe and the heat­ing block. After that, care­ful­ly turn the machine upside down.
  7. Remove the back wall or pull out the bot­tom pan­el.
  8. Take the pump that the heat­ing ele­ment is con­nect­ed to and turn it clock­wise. After that, pull to the side, and the pump will be removed.
  9. Under the plas­tic case there is a rub­ber ele­ment that also holds the heat­ing ele­ment. It will need to be found and dis­con­nect­ed (sim­ply removed).
  10. Now you can remove the old heat­ing ele­ment and install a new one in its place.

When the do-it-your­self repair is com­plet­ed, assem­ble fol­low­ing the same instruc­tions, but in reverse order.

Replac­ing a heat­ing ele­ment is one of the most dif­fi­cult inde­pen­dent types of do-it-your­self dish­wash­er repair. There­fore, if you do not have expe­ri­ence with com­plex struc­tures, then it is safer to use the help of spe­cial­ists for this. In addi­tion, a new heat­ing ele­ment will cost you quite a lot, so putting it on an out­dat­ed mod­el is sim­ply irra­tional.

Common causes of breakdown

In most sit­u­a­tions, dish­wash­er repair is nec­es­sary for the fol­low­ing break­downs:

  • Fre­quent use of the dish­wash­er. Of course, this prob­lem is unlike­ly to affect pow­er­ful pro­fes­sion­al devices, but home mod­els often break if you use them more than 3–4 times a day every day. The fea­tures of the fre­quen­cy of use are described in the man­u­al for using the machine.
  • Poor qual­i­ty water. When var­i­ous con­t­a­m­i­nants accu­mu­late in water, it becomes dan­ger­ous not only for the human body, but also for devices that work in direct inter­ac­tion with it. The con­se­quences of such work can be plaque and rust.
  • For­eign objects have entered the device. It can be left­overs from food, such as bones. Before start­ing a dish­wash­ing cycle, care­ful­ly check the device and car­ry out an ini­tial clean­ing.
  • Sud­den pow­er prob­lems. This prob­lem is rel­e­vant if the elec­tric­i­ty was turned off dur­ing the wash­ing cycle. In this case, the cycle is abrupt­ly inter­rupt­ed, as a result of which var­i­ous fail­ures may occur in the oper­a­tion of the device in the future.
  • Poor qual­i­ty deter­gent. To avoid repair­ing the dish­wash­er with your own hands, it is best to use a spe­cial deter­gent. There are even options select­ed or rec­om­mend­ed specif­i­cal­ly for cer­tain brands of cars.


The dish­wash­er can dete­ri­o­rate sim­ply from old age and dete­ri­o­ra­tion of the mech­a­nism — not a sin­gle ele­ment of house­hold appli­ances is immune from this. In this case, do-it-your­self repair will sim­ply be inef­fec­tive.

How to avoid dishwasher repair?

No mat­ter how sim­ple a break­down is, the repair process always requires costs — mon­ey or time. You can avoid this by fol­low­ing the rules pre­scribed in the instruc­tions for using the device, as well as observ­ing the fol­low­ing sim­ple rec­om­men­da­tions:

  • When burnt food or hard pieces remain on the dish­es, the dish­wash­er may not be able to han­dle it. There­fore, you must first scrape off the soot your­self.
  • It is worth using rinse aid or spe­cial dish­wash­er salt, because these prod­ucts pro­long the life of the machine and sim­pli­fy its work. It should be remem­bered that the tool must be used in mod­er­a­tion, because if you go too far with it, it will also dis­rupt the oper­a­tion of the device. An alter­na­tive dish­wash­er deter­gent is All-in-One tablets. They include both salt and rinse aid.
  • You can extend the life of your dish­wash­er by clean­ing the fil­ters after every cycle. In almost every device, they are locat­ed in the bot­tom area next to the drain.

The dishwasher washes for a long time, heats the water, does not dry — what to do? (video)

In this video, you will learn why the device does not dry dish­es and wash­es for a long time, and how to fix this prob­lem. You will also hear help­ful tips:

Use your dish­wash­er only in accor­dance with the rec­om­men­da­tions and in time pay atten­tion to devi­a­tions in its oper­a­tion. Remem­ber that ear­ly detec­tion of a prob­lem can great­ly sim­pli­fy its solu­tion. Only in this case the device will serve you for a long time.
