At the time, the British magazine conducted a survey of readers of the quality of household appliances.The unequivocal conclusion was only one - the hassle of home appliances there.And both models of the elites - the class, after 5 - 6 years are beginning to falter.Worthy of attention to their conclusion on the reliability of dishwashers leading brands.So the leaders of longevity among the British brands named Ariston, Bosch and Electrolux.
But, as has been said, even the most reliable home helper falters.And when that happens, two exit: tuck your sleeves and take on the repairs yourself, or call for help from a specialist service center.In favor of the first option says statistics - namely, most dishwasher malfunctions are eliminated at home.And in the statistics service centers takes the leading place - "no discharge".
So small and not very complex problem it is possible to eliminate most, but for this it is necessary to get acquainted with the
- design dishwasher
- most common faults and their solutions
- No display, press the buttons on the machine does not respond
- No water supply
- machine is turned on, the water passes fence, but does not start washing
- No draining
- Lack reverse
- Leak machine
- machine makes no sound of its characteristic
- lack of hot water
- No drying dishes
housing, as in any household appliances, serves as the base on which are placed all the major components and assemblies of the machine.The main elements of dishwasher include:
- Control Panel, which is always located on the front side of the machine.It consists of a digital microcontroller (timer), the control buttons and indicator display (as an indicator thereof may be used a beam that is projected onto the floor surface).
- spray blocks or impeller.It is a system of water supply for washing dishes.It consists of a system of pipes and nozzles (two of them: upper and lower).The special design of water and detergent is fed under high pressure, which ensures high quality of washing dishes.
- Float switch - a means of protection from water leaks.The hollow plastic cylinder with a certain amount of water emerges and thus closes the contacts.Depending on the constructive solutions, these contacts close the circuit controlling the pump of pumping water or carry out an emergency shutoff valve supplying water to the machine.
- drain assembly consists of a drainage pipe, which is connected to a common network sewerage and drainage pump.The principle of operation is identical to the sink for washing machines, who knows.
- water inlet integrated with the intake valve, which is controlled by a digital microcontroller.
- water pump is used for supplying water to the sprays, and in some models and for draining water.Typically, co-located with the motor, which starts the pump.
- filters are designed for "catching" the remnants of food and other items.
That's all the most important and the most common faults in the elements of dishwashers.Of course, different manufacturers can be added other units that extend the functionality of the unit.But all of the above - framework to deal with it, you will easily be dismantled and the individual elements of the design of your car.
most common faults and their solutions
To repair the dishwasher with your hands, you must have a minimum set of tools, namely:
- screwdrivers: Phillips, flat and hexagonal (as shown in the image);
- meter with a scale measuring the resistance (ohms);
- pliers and wire cutters.
No display, press the buttons on the machine does not respond
If there is no indication at all - check for power at the outlet with a multimeter.If there is power in the socket, the machine will have an autopsy.
If there is indication of the buttons and the display, but the launch of the program is not going on - check the density of the closing doors.It did not help - to repair washing machines Zanussi require disassembly of the machine.
At the bottom of the machine under the front panel to be the junction box terminals.Tension on the cable gets into the box, and only then through the control contacts at odds on.It is therefore necessary to remove the panel and check the status of the terminal.This place is exposed to humidity and therefore contacts may well oxidize.If so - clean the joints with sandpaper.
Once reached the box and if no visual damage to cables and connections are found, it is necessary to ring the power supply and to determine the injury.Disconnect the input voltage to the box and rang them multimeter (the machine is disconnected from the network, and running water, and drained all the water).Both conductors have to call each device to a prescribed scale measuring the resistance, ieIf the conductor purposes - should be short, if you like to connect two probes together.Faulty cable from the wall outlet to the box You can easily replace their own, and if then the machine will come to life - wonderful.If not, the repair of dishwashers Siemens or other brands, the two outputs: call a specialist or at your own risk seek the fault in the circuit below. \
to select the second option, ieSearch yourself, first of all, you need to find an electrical schematic diagram of your dishwasher model.And then step by step to verify the whole chain.For this purpose, the joints to break the chain and using a tester to check the operation of all chain links.
For easier understanding of the scheme and are some troubleshooting information:
- Scheme English letters abbreviated all the colors of the wires, they all have a different color, so it is easier to find a desired area of the circuit.So be careful and not go wrong.An example of such designations: BK - Black, TR - yellow-brown with a red stripe, W-BK - white with a black stripe, BR-O - brown with orange stripes, etc.
- small circles in the diagram indicate locations of cable connectors in these areas is necessary to break the chain and carry out measurements;
- dashed line indicates that data group of contacts and the circuit elements are located inside of a block, for example the starting relay or panel keys (the diagram circled beside the name of the place specified block and the connection point with the numbers and titles of the contacts).
Note.For any circuit should be the beginning and end, ieto power launched an element chain is always necessary to "+" could fall to minus.Carefully trace the path of the inclusion of your electrical circuit element (either bimetallic or heater).It's like a route from point A to point B if there is a break somewhere - so standstill, the voltage does not take place, all the elements are not able to work.
No water supply
If the water tap is open and the machine is not taking on water in the system, then a clogged filter mesh or the faulty water supply valve.Valve and grid located at the bottom of the machine in place in the water entering the machine.It is necessary to disconnect the machine from the pipe, remove the cover and check these items.If the mesh is clogged, it must be washed with water.The efficiency of the valve, or rather its coils can check tester.To do this, disconnect terminals, and we measure the resistance of the coils.If the device indicates a short (as in connection with the probe) - coil has interturn fault.If zero resistance, so there is an open coil.If there is a certain resistance value - the winding intact, but the problem is inside the valve.In all cases, you have to buy a new inlet valve, and the same with the same capacity.
machine is turned on, the water passes fence, but does not start washing
Determine the sound - "buzzing" whether the motor.The answer is yes then it is likely that something is stuck or the motor or pump.How to check and unlock the pump is specified in the video below.
Just cause may be damage to the motor windings.To check it is necessary to disable its conclusions and a multimeter to check for open winding or interturn circuit.In the case of the mentioned faults must be replaced with a comparable engine or rewind, you will carry out an expert.
If there is no sound of the engine start-up and repair of dishwashers Indesit and search for damage should be implemented in a similar way as described in the first fault, ieIt must be guided by the circuit diagram to go and look for the cause breakage.
No draining is necessary to check
sewer - not clogged drain.The reason may be a blockage or damage to the drain pump.To determine the cause of the fault must be removed and checked for clogging.Also, using a multimeter you can check the serviceability of the windings.
may also cause contamination of the filter, how to maintain them in the video shown below.
absence of reverse
cause of the fault may be damage to the motor windings, and the fault timer.With the last all is not easy, so if you suspect a timer - contact a professional repair washing machines Bosch or other manufacturers.
leak of the machine can be connected with the door seal is checked visually.If his condition is unsatisfactory, you can buy new and without any problems be replaced.
In the case of a leak from the machine, you must determine the location of the leak.To do this, remove the panel, for that would get to the bottom.This allows to visually determine the location of a leak, as a rule, can be damaged seal pump supply hose or the drain.
machine makes no sound of its characteristic
necessary checks for the presence of metal or glass fragments.Chance of bearing wear.If the quality has fallen dishwashing, it may indicate damage to the pump impeller.Therefore, if there is no debris, it will be necessary to disassemble the engine and pump for that would determine the degree of wear of the bearings.The motor shaft should be smooth and soft run without obstacles.
lack of hot water
This fault may be caused by the following reasons:
- faulty heater;
- faulty temperature sensor;
- fault timer.
With the first malfunction can understand yourself, disconnect the heater and check the resistance.If open - buy a new me.With the other two will be difficult, for example, to check the timer needs to know the entire sequence or algorithm switching contacts for heating the heating element.Therefore, the optimal solution for the majority of users will appeal to the service center.
No drying dishes
If the machine is provided with a turbo-drying dishes, this failure indicates damage to the windings of the fan motor or damage the circuit switching thereof.Winding check just need to get to the terminal the motor fan and check their serviceability multimeter.If the fan is functional - check the entire electrical circuit turning on the fan.
We reviewed the most common faults dishwashers.Of course, just impossible to describe, but we hope that we Fault finding highlighted sufficiently, that we could begin to self-repair washing machines.It is worth mentioning that the repair of dishwashers Electrolux, or any other with their hands should be made at the expiration of the warranty period.Otherwise, you lose the manufacturer's warranty, but to decide, of course, you.
