Decoding error codes dishwashers Bosch

Each dishwasher has a self-monitoring system. While the bosch dishwasher is operating normally, self test does not manifest itself. If a problem occurs, bosch dishwasher error codes begin to appear on the screen, symbolizing certain faults.

Difficulties with water heating

E01. This error says about the failure of the system tena contacts or about breaking its integrity. With the appearance of this code, with high probability we can say that the heating element has blown, and its replacement is the only correct solution. If the teng is okay, a possible suspicion falls on the temperature sensor.

E09. Similar mistake with teng flow type. Such a malfunction is typical for machines where the heating element is placed not in the tank, but in the depth of the distribution pump. The classic error correction option is to replace the defective item.

E11. This code indicates that there is no power supply to thermal sensor. It is also possible to break the communication between the sensor and the control system. To eliminate the error you need to check:

• operability of the sensor contacts;
• wiring to the sensor;
• contact system in the control unit.

E12. Signal about accumulation on the surface of the ten lime scale or dirt, which leads to a lack of heat transfer of the heating element. In most dishwashers, it is possible to clean the PETN and restore normal operation.

TEN flow

Complications of the drain system

These problems are not often encountered while operating the dishwasher. Bosh, however, must be treated with the utmost care.

E3. This signal interrupts the work of the dishwasher, if for a fixed time interval it is impossible to get the right amount of water. In new versions of dishwashers, at first the water drains itself, and then the E3 error is fixed on the screen. In this case it is necessary:

• make sure that there is water in the water supply;
• check all the filters;
• make sure in good condition bay valve;
• check the operation of the water sensor;
• determine the state of the pump, although it fails very rarely.

E5. The water tank of the dishwasher is filled with water over measure. This happens if the water sensor cannot stop the process of filling with water in time. Unequivocally defective sensorand in this case it is necessary:

• inspect the sensor tube if dirt has accumulated there;
• whether the wiring to the sensor is good;
• is everything okay with the closing of the filling valve, does it not let the water through.

In very rare cases, such a mistake is about failures in the control system.

E8. This kind of error intersects with a similar one - E3. The reason for this failure lies in the inability of the machine to pump the required amount of water in the pan. As a result, both the pump and the heating element cannot start their work. The reasons are the same as in the detection of the error E3.

Filter check

E16. The manifestation of an error with this code indicates that water randomly and non-stop flows into the machine. Almost always the cause is extraneous fraction, trapped with flooded water and does not allow the exhaust valve to close.What needs to be fixed:

• clean the bay valve;
• make sure that the water sensor is in good condition;
• Check for excess foam from the composition for washing.

E17. Difficulties with the water supply in the dishwasher cause this error. A fault of this type is quite specific and indicates a complete or partial failure in the operation of the exhaust valve. A similar indicator may occur when water hammerIn this case, restarting the machine solves all problems. If in the house plumbing system overpressure, then it must be adjusted on the pipes of the riser.

E21. The specified code appears in the case of problems with pumpas a result there is a refusal to drain water. If the pump is normally supplied with power, the operation with the control unit and sensors is synchronized, but the pump does not function, the following situations are possible:

• impeller does not spin (due to ingress of foreign objects);
• sticking of the rotor on the sleeve, you need to clean its surface and lightly lubricate it;
• The pump has passed the wear point and needs to be replaced.

Trouble with blockages

Problems caused by a variety of blockages, according to statistics, the most frequent. For the most part, blockages are formed when the user is too lazy to clean the plates of food debris, before placing it in a drawer for washing.

E07. This code indicates that the items are not laid out in order, and one of them blocked the holethrough which water goes. It is possible that this hole is blocked by food debris.

E25. This trouble lurks when either the pump tube or the drain hose is blocked at the base. The error algorithm is as follows: the effort of the drain pump is not enough to remove dirty water, the sensors transmit information to the control system, and that in turn stops the operation of the Bosch dishwasher. To fix the problem, you need clean the hoses and diagnose the impeller.

E24. Error E24 is understandable to any amateur - problems with hose to drain (kinking or clogging), possible clogging in the sewer. So says the standard instruction, in fact, you need to check the following items:

• their failure by one of the sensors;
• failure of the drain pump;
• software failure in the control system.

Very often, after blowing a hose with a strong airflow from a vacuum cleaner, the problem is easily solved.

Water sensor faults

E4.This code is authorized to state that the sensor regulating the flow of water supplied to the sprinkler does not work. The main cause is usually the blockage caused by calcined scale due to excessive water hardness.

E6. Failure of the sensor clean water. This specialized sensor is located next to the heater for monitoring water quality. As a rule, it is necessary to replace this element.

E14. Incorrect functioning of the sensor responsible for monitoring the water entering the device. To solve this problem, you need to call a professional master.

E15. This error occurs when detecting leakage. The following steps should be taken:

• examine the leak detection pan;
• visually check the hoses;
• Inspect all items for leak detection.

E27. Briefly - the voltage in the network has changed to the lower side and is not 220 volts, the machine stops working. The error often manifests itself in the evening, with the greatest network load. Having chosen the start (till 3 o'clock in the morning) start, the problem is easily eliminated and in the morning clean dishes will be waiting for the hostess.

A better solution is to connect the dishwasher with a voltage stabilizer.

I would like to point out that the fault detection system is necessary to provide substantial assistance in the operation of the dishwasher. In many ways, thanks to her, she manages to find and successfully correct the defects that arise.
