Hansa dishwasher error codes - how to decipher

Dishwashers This brand is produced in China. One of the important features of such devices is the economical use of available resources. This washing mashine brand began its existence back in 1997. However, already at the beginning of the 2000s, this equipment appeared on the Russian market. Most models can be classified as budget or middle class. If malfunctions occur, the owner sees error codes for Hansa dishwashers, which allow them to determine the type of malfunction and put them into working order.

General information

Almost all the latest models of devices include a display on which the Hansa machine can display messages for the owner. If an error occurs, the machine automatically determines its source and issues the necessary code. In accordance with the information received, the user determines what happened and knows what is recommended to be done to clarify the received data and for repairs.

However, older models, many of which are still in use, did not have displays installed. However, the designers provided the opportunity to find out exactly what problem arose. Data is transmitted by flashing indicators installed on the panel. In some models, both methods can be used simultaneously.

Description of error messages

For different Hansa models, the information provided on the display may differ. Therefore, the codes used on most models are provided below.

Error code E01 indicates that the tank is filling with water too slowly. There are many possible reasons for this. Some of them are easy to fix yourself, without contacting the service.

The following reasons may be the reason for this message:

1. It is possible that water does not enter the machine at all. This is possible if the hose is clogged or pinched. Then it is enough to inspect and correct the situation.
2. Sometimes the electronic control of the Hansa dishwasher can prevent the flow of water. This happens if the door is not tightly closed. It is enough to simply close it tighter.
3. When entering the machine, water passes through the solenoid valve. If the latter has become faulty, it must be replaced.
4. The filling level of the chamber is determined using a special sensor. If it gives incorrect data, this may be the reason that water does not flow.
5. Sometimes it may happen that the units and mechanisms work correctly, but the problems occurred with the wiring. In this case, you need to check its serviceability and make sure that there are no burnt wires. If an error is detected, it is necessary to restore the connection.
6. If violations are detected in the operation of the Hansa machine's electronic control controller, then to correct the situation you will need to contact the service for its repair or replacement.

When the E3 code appears on the display, the error relates to the heating system.This manifests itself in the fact that after 60 minutes have passed, the water in the Hansa dishwasher is still not heated to the level required for washing.

In this case, the source of breakdowns may be the following:

1. It is possible that the temperature sensor is broken. If this is the case, then replacement is required.
2. The level sensor is faulty and a new one will need to be installed.
3. It happens that the chamber now has too much volume. This is a sufficient reason for the heating to be insufficient. This happens, for example, if it was not detected in time that there was already enough water in the tank.
4. If the wiring in the circuit that supplies energy to the heating element is broken. Then you need not only to check whether the contacts have come loose, but also to ring this entire circuit to detect a breakdown.
5. Sometimes the heating element shorts to the body. In this case, it is better to replace this unit.
6. If the heater burns out, then only replacing it can help.
7. The operation of the dishwasher is controlled by an electronic board. If there are problems with it, then you need to take it to a specialist workshop. In this case, it is impossible to carry out repairs on your own.

To eliminate the breakdown, you need to take into account that the reasons may be the following:

1. It is possible that the water entering through the plumbing system is under too much pressure. If the water supply is faulty, it is recommended to invite a plumber to repair it.However, there is also a situation when it is enough to simply reduce the water pressure in the hose.
2. A faulty fill valve cannot be repaired; it must be replaced.
3. If the pressure switch is working properly, but there is a break in its circuit, then to repair it you need to ring the contacts and correct the found break.
4. Sometimes the level sensor does not detect a situation when the tank is full of water due to a malfunction. Water continues to flow and overflow occurs. Replacing the level sensor will help here.
5. If the control board does not work properly, it becomes necessary to repair the electronic device. Only a service professional can do this.

For the device to operate, it is important that the machine receives reliable data from its nodes. If the temperature sensor is faulty, code E6 will appear on the display. In order to take action, you need to check the following:

1. It may turn out that the sensor itself is working, but the wiring that goes to it is damaged. In this case, you need to inspect it for damage and call if necessary. Then you need to restore the connections.
2. If the sensor is broken, then there is no point in repairing it - the situation can only be corrected by replacing it with a working unit.
3. The operation of the Hansa dishwasher is organized by an electronic control board. If there is a malfunction in it, then there will be a complex repair that is almost impossible to carry out on your own. To do this, you need to contact a specialist in a repair shop.

If error E7 is displayed, this indicates a malfunction of the temperature sensor. It is necessary to react in this situation in the same way as to error E6.

In a situation where the machine has identified the failure code as E8, the faulty unit is clearly identified - this is the inlet valve due to which water does not flow. In this case, do the following for repair:

1. If the valve is broken, you need to replace it with a new unit.
2. The drain hose may be connected incorrectly.
3. A triac short circuit occurred on the control board. Now you need to call a specialist who will check and repair or replace the control board.

Conclusion

Knowing the error codes will help you detect and correct faults in Hansa dishwashers. In fact, in addition to the listed signals, other diagnostic options can be used. In order to use them, you need to find out their descriptions in the instructions that came with the dishwasher.
