Error codes for Kaiser dishwashers

Dishwashers from the German company Kaiser have conquered markets in almost all countries of Eastern Europe and Russia. But no matter how much the developers care about extending the maintenance-free operation of their products, the time still comes and the equipment begins to gradually fail. This especially often happens when operating rules are violated or low-quality water is used.

The developers of Kaiser dishwashers took into account the requirements of customers and developed a self-control system. Its essence boils down to the fact that in the event of any defects, the Kaiser dishwasher system analyzes the breakdown and provides the user with information in the form of error codes.

Difficulty deciphering the error code

There are a number of breakdowns that distort one or another error code. We are talking about malfunctions in electronic circuits. For example, any damage to the electronic control circuit of a Kaiser machine can lead to a malfunction of the self-diagnosis device, and then various error codes may spontaneously appear on the display that do not reflect the true breakdown.

Some codes in Kaiser dishwashers may combine not a specific single defect, but several breakdowns, with different mechanisms and components. Therefore, it is recommended to be very careful and not trust 100% in decoding errors. If possible, it is recommended to find other ways to determine the true error.

However, the developers of Kaiser dishwashers believe that it is better for the user to know the essence of the defect and be able to answer the question of what to do and how to correct the situation.

Error E1

Error reports about a faulty door lock. The control circuit of the blocking device does not receive a signal to activate it.
The absence of a signal may be due to the following reasons:

• The loading hopper door is not completely closed;
• the locking lock or sensor is damaged;
• There is a malfunction in the electrical control circuit of the locking device.

To resolve the error, it is recommended to do the following:

1. check that the door is closed tightly;
2. check the functionality of the locking lock. If necessary, it must be replaced;
3. Check the electrical circuit for controlling the locking device. Pay attention to the presence of electrical connection between the board and the blocking actuator. If necessary, the cable is replaced.

Error E2

Error warning that the filling time has been exceeded. This failure can occur for the following reasons:

• low pressure in the water supply network;
• the solenoid valve is damaged;
• the intake hose is dirty or the filter device is clogged.

To repair damage to your Kaiser dishwasher, you must do the following:

1. check the pressure in the water supply system.Maybe it has dropped to a critical value or the water supply has stopped;
2. check the functionality of the shut-off valve. Maybe it's just closed;
3. check the electronic circuit of the filling valve;
4. disconnect the filling hose from the PMM and clean it. Inspect the cleaning filter, and if it is clogged, clean or replace it.

Error E3

Error symbolizes about exceeding the water drainage time. In a Kaiser dishwasher, this error indicates the following failures:

• the pump impeller is blocked;
• the drain filter is clogged;
• The drain hose or siphon is clogged. The sewer system may be clogged.

Troubleshooting methods:

1. it is necessary to remove the pump cover and clean the impeller from blockages;
2. clean the drain filter. To do this, you need to open the chamber door and remove it from the tray. The filter is cleaned under the pressure of running water;
3. remove the drain hose and, if necessary, rinse under running water;
4. check the siphon and sewer system. If necessary, they must be cleaned of contamination.

Error E4

The code is displayed when the water level sensor is triggered. This indicates an overflow of water.
The following problems may be the cause:

• water intake valve malfunction;
• failure of the pressure switch;
• malfunction of the electronic module.

To repair the listed damage in a Kaiser dishwasher, it is recommended to do the following:

1. check the water intake control valve. If it is damaged, it must be replaced. It cannot be repaired;
2. check the operation of the water level sensor. A multimeter is used to check. When the sensor is working, its resistance should slowly decrease to zero.You can also determine its performance by purging the pressure switch tube. If clicks are heard during the injection process, this indicates that the sensor is damaged and needs to be replaced;
3. determine the malfunction of the electronic module, and only a specialist can repair it.

Error E5

To determine the location of the short circuit, it is necessary to check the insulation resistance of all listed elements of the electrical circuit. A megohmmeter is used for this. If a short circuit occurs in any part of the electrical circuit, the device will show a zero insulation resistance value. Depending on the complexity of the insulation failure, it can be restored or individual elements of the electrical circuit replaced.

Error E6

In the Kaiser dishwasher error code warns about a break in the thermistor circuit. Contact failure can occur in any element participating in the water heating circuit. This can happen equally in the heating element, as well as in the temperature sensor or wiring. Before troubleshooting, it is necessary to carefully diagnose and locate the damaged element.

Error E7

This code appears when there is a short circuit in the temperature sensor. The breakdown is very serious, so experts recommend contacting a service center.

Conclusion

This is a complete list of Kaiser dishwasher error codes. However, experts do not advise rushing to fix any breakdowns on your own.If an error code appears on the display during operation, there is no need to panic. First you need to turn off the machine and let it rest for 30-40 minutes. Then the machine turns on again. If the error code does not disappear, then you need to decide to fix the defect yourself or send it to service.
It is better, of course, to invite a specialist or contact a service center. Incompetent intervention in a complex mechanism can cause much greater harm.
