Dishwasher device

Any dishwasher consists of several main nodes:

• TEN.
• Engine.
• Working chamber with rocker arms.
• Drain pump.
• Exhaust valve.
• Control board.

Important! In some models of such household appliances there are heat exchangers, turbo dryers and some other modules, but, as a rule, the structure looks exactly like that. Therefore, independent repair of the device is possible without the involvement of specialists. In addition, in this case, you can save a lot of money.

The dishwasher does not turn on:

• Sometimes household appliances break down so that it simply ceases to show signs of life - no indicators light up, no modes are selected - absolutely, nothing happens to the dishwasher. But do not be sad about this, because the problem often lies on the surface. For example, a broken outlet may be the cause of the malfunction - plug in some other electrical device and make sure that there is power. If the outlet fails, replace it and check the wiring condition.
• If the power goes, but the dishwasher still does not show signs of life, then you need to check the fuses on the power board - they can also fail due to, for example, a power surge. In this case, do-it-yourself DIY repair of the dishwasher comes down to a banal replacement of fuses, which can be easily found in specialized stores. However, do not try to put “bugs” here, since this approach can lead to the most sad consequences (even before fires).

Important! A blown fuse may be a sign of some kind of internal malfunction of the device - if the failure occurs again, it is worth checking the entire device.

• Many dishwashers are equipped with mechanical power buttons. They are quite reliable, but occasionally contact groups begin to fail - contacts are oxidized or burn out from sparking, factory defects affect. In the end, this can lead to the button breaking completely. As a result, no matter how much you press it, nothing will happen. Therefore, after fuses, it is worth checking the switch, it is likely that its life has expired.

Important! Sometimes the reason for the lack of efficiency can be a violation of the integrity of the connecting wires - while the repair of the Ariston dishwasher with its own hands will consist in their partial or complete replacement (the wiring tends to become obsolete). The control board may also fail.

The appliance does not start washing dishes

Repairing a dishwasher often involves finding and eliminating not entirely understandable breakdowns. If the device does not show signs of life - this is one thing, however, if it turns on and does not start to execute a given program, then this is a completely different matter. The reasons for this may be different:

• The door is not tightly closed. In this case, you just need to close the door more tightly - that’s the whole repair. In some cases, opening and re-closing the loading door helps.
• The engine has failed (it is also a circular pump) - this is a more serious problem, for the solution of which it is necessary to find the same motor - you can search it in specialized stores or service centers.
• One of the sensors broke.
• A clogged filter is not the most common cause of a malfunction, but is eliminated by thorough cleaning. In the event that the holes in the rocker arms are clogged, then you should arm yourself with a match, a toothpick or an awl, and then consistently check the patency of the holes.
• Control turned off - in this case, try to completely turn off the device and turn it on again.
• Control board malfunction - it does not turn on the motor, does not open the exhaust valve, or does not respond at all to any user actions. In this case, DIY repair of Electrolux dishwashers at home involves a complete replacement of the board, which can be bought at service centers or specialized online stores.

Important! Often, dishwasher malfunctions are displayed in the form of code errors, which are generated as a digital combination on the panel or as a combination of burning LED indicators. Using these prompts, you can easily calculate a failed node.

If you decide to purchase a new dishwasher, be sure to pay attention to the following models:

• Indesit Dishwasher dsg0517. 
• Dishwasher Bosch Silence Plus.

No water enters the machine

If your dishwashing machine does not draw water, it is possible that the cause of the problem lies on the surface.

Reason 1

First, check for the presence of water in the water supply system - it could just be turned off for the duration of the technical work. Also, troubleshooting can be reduced to checking the ball valve and the inlet hose.

Reason 2

Lack of water may also be due to filter malfunction. One of them is located in the inlet hose - it is a thin mesh that traps mechanical impurities. Repair in this case comes down to checking and cleaning this mesh.

Important! If there is an additional coarse filter in the inlet, then make sure it is working.

Reason 3

Another possible reason due to which water does not get into the dishwasher is the lack of operability of the exhaust solenoid valve. Do-it-yourself Bosch dishwasher repair steps are as follows:

1. Check the valve with an ohmmeter.
2. Check the supply voltage to the valve.
3. Ring the wires with a multimeter.

Important! In some cases, the malfunction may lie in the control board - here the triac breaks down, which controls the voltage supply to the valve.

The appliance does not drain water

If your dishwashing device has stopped draining water, then in most cases the repair will be reduced to replacing the drain pump - this element breaks down quite often. For some dishwashers, the cost of this part is very expensive, but there is no other way - you will have to make a replacement. Also worth checking out:

• The integrity of the wires that lead to the drain pump.
• Patency of the drain hose.
• The presence of supply voltage to the pump.

Finding the cause of the malfunction of the dishwasher, we again rest against the most commonplace things. For instance:

• Lack of proper drainage is often caused by a clogged drain hose.
• Some users push this hose, which also leads to a hose break.
• It is necessary to verify the normal operation of the siphon - its blockage is also possible.

 

Diagnosis and repair of the pump comes down to checking the resistance of its winding (you need to find the nominal resistance of the winding for a specific pump model in the network and make a comparison). If the drain pump does fail, replace it. In addition, during the repair, check the power supply at the moment when the drain should begin.

Important! Repair of individual dishwashers can be complicated by the fact that some flow pumps have a built-in instantaneous water heater, as a result of which repair will be much more expensive.

Dishwasher leaking

If a puddle of water forms under your dishwashing device, then it's time to perform a comprehensive check:

• Inspect the boot door seal - it may be that it has served its time and needs to be replaced. Do-it-yourself repair of the dishwasher comes down to acquiring a similar seal and replacing it.
• Inspect all available clamps - often loosening one of them leads to the formation of leaks.
• Check the integrity of the inlet hose - it could overheat or leak. Also inspect all seals and replace as necessary.
• Carefully inspect the working chamber - often steel is exposed to through corrosion. Thus, the repair consists in restoring the integrity of the tank (for example, flat soldering).

Important! Models of dishwashers that are equipped with the Aquastop module will help prevent water from getting on the floor - it stops the flow of water when the water inlet hose breaks or if water gets into the appliance tray.

Noise in the dishwasher

Such a household appliance as a dishwasher is prone to making noise, the source of which is flowing water, an engine and a drain pump. Some models are louder, some are quieter - it all depends on the parts used and the sound insulation of the case.

If the dishwasher starts to make noise louder than usual, it needs repair:

• Disassemble the device and inspect the engine - it is possible that bearings are rustling here, in which water could get through the leaky seals. Repair is simple - replace the seals and the bearings themselves. Sometimes the repair process can be reduced to a complete replacement of the entire motor.
• Check the pump - any impurities that may cause an increase in noise levels might be stuck there.
• Check the rotating rocker arms - perhaps they are the ones making noise or the mechanism that sets them in motion.

Important! Making repairs to the dishwasher with their own hands, the craftsmen recommend periodically conducting professional examinations - they make it possible to detect developing failures in time.

The dishwasher does not heat water

Dishwashers wash dishes in hot water, as washing something in cold water is very problematic. For heating in this device is responsible for the heating element - flowing and classic. Its breakdown leads to the fact that the device stops heating water, as a result of which it is possible to stop the program and the lack of a normal result. Repair consists in replacing the heater - you will have to find a similar part.

Important! Worst of all, if in the device there is a heater, which is combined with a drain pump.

Other reasons for the lack of heating include the following:

• Malfunction of internal wiring - repair consists in ringing the integrity of the wires and replacing them.
• Malfunction of the temperature sensor, which gives the command to turn off the heater - the repair comes down to replacing the sensor.
• Failure of the control board, which does not supply power to the heating element.

Important! But most often the heater itself breaks down.

The appliance does not dry dishes:

• Condensation drying in modern dishwashers works in such a way that the dishes are dried by themselves, that is, in a natural way. Evaporating water collects condensate on the top of the chamber and flows down. In order to improve the quality of evaporation, the developers of such household appliances raise the temperature of the water when rinsing, thereby heating the dishes. Therefore, the presence of water drops is the norm. No repairs are needed here.
• The turbo dryer works differently - it dries dishes with the help of hot air, which is generated using a special heating element and fed into the working chamber by a fan. If the turbo dryer does not dry, then a broken fan may cause a malfunction. If it rotates, but the dishes still remain wet, then the problem may lie in the failed heater. Repair is simple - replace a failed module.

The dishwasher is shocking

The most common reason that the device is beating current is the failure of the heater - it must be checked first. Repair consists in checking the resistance between the housing of the heating element and its contacts. If the multimeter showed a breakdown, then the heater will have to be replaced.

It is also worth checking the following:

• The integrity of all the connecting wires inside the device - perhaps, insulation somewhere was leaky, partially closing to the case.
• Motor dishwasher - there may be a breakdown on the body. Repair consists in replacing the motor or rewinding the windings.
• The integrity of other electrical components.

In order for the appliance to always wash dishes with high quality, you should choose a good detergent. Therefore, we suggest that you familiarize yourself with our dishwasher rated.
