The characteristic dishwashers malfunction situation applies when the dishwasher is cold water. At the time allowed to connect hot, but this is an emergency situation. Dishwasher can not be regarded as a functioning and in need of repair.
The main feature of such a failure is a decrease in the quality of washing, the abundance of food debris and grease on the dishes after its completion. Problem sources can be varied. They should be divided into two groups: a violation of the rules of operation and technical problems.
misuse
Modern PMM devices robust and durable. Therefore, if the dishwasher under the Bosch brand name does not heat the water thing, most likely in use error. These include:
- error when connecting the drain;
- Untimely cleaning of the filter;
- the wrong choice of operating modes.
drain connection
When connecting the drain, experts recommend making two loops without kinks. One at the entrance to the car, the other closer to the junction with the pipe siphon. This prevents the reverse current from the sewage water.
Improper installation of the hose kinks disrupts the normal circulation and heating process, resulting in machine does not heat the water. To restore the operation of the device it is necessary to shift the drain under the instruction requirements.
trash filter
Another cause disturbances of circulation water is clogged "junk" filter. It consists of a grid system and grid cups nested in each other and screwed into the "sex" detergent compartment. Designed for filter delay trash scrubbed with utensils. Neglect leads to cleaning:
- to clogged grid elements;
- the water starts to accumulate in the hopper;
- not held in the holding tank;
- Pump forced to compensate for the lack of it;
- as a result of heating element can not cope with the heat.
The solution is simple, it is necessary to urgently carry out cleaning of the filter and restore the circulation of fluid, if not parallel to the other problems arose.
modes of operation
Such technological aids as a dishwasher or Hansa Zanussi can be equipped with a large number of programs that are able to work on an enhanced functionality. But in any case, the three main modes:
- standard at about 60 ° C for washing secondary contaminants;
- amplified, wherein the water is heated to 70 ° C, is used for washing heavily soiled;
- sensitive to the temperature not above 45 ° C required for use with fragile objects or light load.
If the operator makes a mistake, and selects the delicate cycle for heavily utensil, the device will not be able to heat the water to a desired temperature, dishes remain dirty. Output is obvious, again run the dishwasher with a properly installed regime in the future not to make mistakes.
technical issues
Failure of structural elements is the natural result of many years of use. But more often it is a problem all the same abuse, which can not withstand even the most reliable units. As a result, they can "please" their negligent owners loss of operating temperature. Structurally, this may be due to:
- faulty thermostat;
- failure of PETN;
- a malfunction of the control unit.
Faulty thermostat
This is one of the weaknesses of the most popular machines, such as a dishwasher Zanussi. Before embarking on his replacement, it is necessary to check the operation of the sensor. This will require open access to the internal electro-mechanical parts of the device.
Proceed as follows:
- disconnect the unit from the communication (the water supply, plums, power);
- remove the basket from the washing compartment;
- dismantle the rocker sprinkler and filter recycling;
- turn the machine for access to the lower cover;
- reverse side fasteners;
- disconnect the drain tube heating block;
- lift the bottom;
- find the sensor on the heater, which is assembled in a single block with a circulating pump;
- free and clean contacts;
- multimeter to measure the resistance.
If the test results do not meet the normal need replacement parts for the same.
Failure of PETN
In modern dishwashers the heating elements are mounted in a single unit with circulation pumps. Since the block expensive and causes lack of heating varied, it is necessary to ensure breakage. This will require open access to TENu the manner described above. After that:
- visually determine block the circulation pump and the heater;
- remove his half-turn clockwise, unless otherwise provided in the Regulations;
- to remove the sensor unit;
- if any, release the other fastening elements of the block;
- rid of all the contacts and extract heater.
Scheme conditional disassembly may be adjusted in accordance with the design features specific model. After dismantling the faulty heating element should be replaced with a new one and reassemble in reverse order.
The fault control unit
This part of the machine generates the control signals in accordance with the mode selected by the operator. They act on other equipment, and provide the necessary consistency of his work.
Repair of the control board is not recommended to carry out on their own, without the involvement of a specialist.
The latter can be extended to all the faults listed, with no experience of such work, and the minimum required knowledge. If repairs are carried out on their own, should be as careful to avoid damaging expensive equipment.
