Siemens dishwasher - error codes

The use of dishwashers provides significant assistance to the housewife, reducing the amount of housework. However, this happens as long as the machine is working properly. If problems arise, then the error codes of Siemens dishwashers will help you determine what to do next. They will help you determine what happened and how to fix the problem.

Review of possible breakdowns

If diagnostics say that an error has occurred, it is important to ensure that it is not a random failure. In order to do this, you need to unplug the machine, wait a few minutes, then turn on the dishwasher again. If upon restart the error is still displayed, this means that repairs need to be made. Siemens dishwasher.

Errors E1-E6

If the display shows code E1, then the problem is related to the incorrect operation of the heating element. However, this error in Siemens machines can have various causes:

1. The most common of them is the occurrence of current leakage to the housing or the presence of zero resistance at this node.
2. If the element that is part of the control board and is responsible for the operation of the heating element is broken.
3. The safety thermostat has malfunctioned.
4. Incorrect functioning of the flow sensor.
5. The water level sensor (called a pressure switch) gives incorrect values.

If such a breakdown occurs, you need to check the electrical characteristics of the corresponding components of the Siemens dishwasher. If possible, the used element must be replaced. If there are errors in the functioning of the control board, you must contact a specialist for repairs.

Error code E3 indicates that there is not enough water in the tank. Of course, it’s not difficult to replenish the supply, but the problem is that in this situation the cause was a breakdown Siemens dishwashers. There may be one of the following reasons:

1. The filling system includes a hose, valve and filter. If they are clogged, then water will not be able to flow through them. To correct the situation, it is enough to inspect them and clean them, if necessary.
2. The inlet valve may have broken. It must be inspected and replaced if necessary.
3. Sometimes problems arise when the drain valve does not work well. It may be blocked. In order to study the situation, you will need to inspect the pump impeller. Perhaps foreign objects got there.
4. Sometimes the reason may be that the pressure switch is broken. In this case, a replacement must be made.

When the water switch is faulty, error code E5 can be seen on the display.

In this case, the problem usually occurs due to one of the following reasons:

1. The unit is clogged.
2. Engine dishwasher works with malfunctions, as a result of which this node switches incorrectly.

In the first case, it is enough to inspect the switch and remove the blockage. In the second, the situation is more serious - the engine has probably failed, which most likely needs to be replaced.

Sometimes it happens that there is too much water left in the tank. This is indicated by the E5 code, which will be shown on the display of the Siemens machine. Here are some possible reasons for this:

1. The pressure switch data is incorrect.
2. The drain hose does not allow water to flow through because it is clogged.
3. The exhaust valve is not functioning properly.

When a Siemens dishwasher displays this error code, you need to check for dirt. If they are found, it is necessary to clean them. To control the correct operation of the pressure switch, you need to check its electrical characteristics. If a malfunction is detected, this unit will have to be replaced.

Errors E7-E18

When code E7 is received, it means the dryer is not working. The cause is a non-functioning fan. In some cases it can be repaired, but sometimes it is better to buy a new one.

In order to start the washing process, it is necessary that the volume of water. Which is in the tank has exceeded a certain minimum level. If this does not happen, error E8 will be issued. One possible reason could be low water pressure in the plumbing system.However, we cannot exclude cases where the heating device or pressure switch of the dishwasher is faulty.

If the flow-through heater does not heat the water (error E9), this may, for example, mean that this unit is burnt out or there are problems with the wires. Which lead to him. In this case, you need to check the contacts and measure the electrical parameters of the heating element. If there are burnt wires, they must be replaced. If the dishwasher unit is faulty, it will need to be replaced.

If error E11 occurs, the Siemens machine starts the work cycle, but the heating element does not work. A malfunctioning thermostat can lead to this result. The problem can also occur when wires burn out or the control module malfunctions.

Sometimes a breakdown results in the heating element being dirty. This is indicated by code E12. The same diagnosis is also possible if a layer of scale forms on this unit. If this happens, to restore functionality dishwashers It is enough to remove the contamination.

An alarm signal is a message that the water temperature in the Siemens dishwasher is too high (E13). This can happen not only due to a malfunction, but also as a result of an incorrect connection of the dishwasher to the hot tap. However, it also happens that the problem arose due to improper functioning of the thermistor.

E14 indicates that the water flow sensor is not working properly. In this case, it will need to be replaced.

If this Siemens model is equipped with the Aquastop leakage protection system, then a situation is possible when it tripped (E15). In this case, you have to find the place where the leak occurred and fix it.

When water fills the washing tank spontaneously, this indicates a malfunction of the inlet valve. However, error E16 also has other possible causes:

1. The foam level in the tank is too high.
2. The water level sensor is faulty.

You can try removing the foam and see if it works Dishwasher Siemens. If this is not the case, then you will have to replace the non-functioning unit.

E17 means that faults were detected during filling. This occurs when the flow sensor is faulty or when the incoming water pressure is too high.

Malfunctions related to water drainage

• Code E21 indicates a breakdown of the pump when draining or a clogged impeller.
• At E22 We are talking about a loss of communication between the pump and the control module.
• If there is a break in the electrical winding of the pump, then the error code that will be displayed on the display is equal to E23.
• If the drain does not occur at all, then you need to check the drain hose. If you clean it and make sure it works, then the reason for the error E24 eliminated.

Other codes

Conclusion

Knowing the error codes will allow you to quickly and reliably diagnose the problem and take measures to correct it.
