Siemens Dishwasher Error Codes

Siemens dishwasher errorsSiemens dishwasher self-diagnosis indicates that the machine stops when a malfunction occurs and an error code appears on the display. Users who see this for the first time think that the dishwasher is broken, they will have to turn it in for repair. However, you should not panic, but it’s better to figure out what the appeared code means, it may turn out to fix the problem yourself. To do this, look at the instructions for the machine or read this article.

Errors of discharge and gulf of water

We decided to divide all error codes of Siemens dishwashers into two groups. First, we attributed those errors that in most cases are resolved independently, without the involvement of specialists, and they are mainly associated with the discharge and collection of water.

E3 - an error code informing that when typing water does not reach a certain level in the time allotted by the program. Old cars of this brand stop in this situation, and water is collected until it reaches a certain level. In newer dishwasher models, water may drain. The reasons for this work are as follows:

  • “Aqua stop” system is faulty;
  • the drain pump does not work;
  • the filling valve is damaged;
  • the water level sensor does not work;
  • there is a blockage in the filter on the water supply.

The first thing to check is the filter located immediately behind the inlet hose at the inlet to the dishwasher and inlet valve. Then the Aqua Stop hose is checked, if necessary it needs to be replaced. Least of all breaks the pressure switch and pump, the replacement of which will require certain skills.

E5 - error code that occurs when the water overflows above the level. In this situation, the cause is a blockage in the tube of the water sensor, or a breakdown of the sensor itself. In addition, water can all be drawn into the dishwasher, if the water supply valve is stuck in the open position, such a valve can only be replaced.Siemens dishwasher errors

E8 - error code indicating a small amount of water collected. At the same time, the heater of the dishwasher does not receive a signal to turn on, and the circulation pump cannot “drive out” the water because of the reduced pressure, as a result, the washing process does not start. A common mistake is the low pressure of the gulf of water. There may be a mistake in the pressure switch.

E15 - error code, when the Aqua Stop protection system is triggered, most likely water has got into the pan. To eliminate the error E15, you need to drain the water and find a place for leakage, for example, leaky connection of hoses and pipes. It happens that the “Aqua Stop Sticks” float needs to be tilted to fix this, and then the error e15 will disappear.

E16 - is displayed on the screen during spontaneous water intake into the dishwasher tank. The reasons for this may be:

  • increased foaming due to overdose of the detergent or its use for other purposes;
  • malfunction persostat or filling valve.

E17 - an error that occurs when collecting water into the tank of the dishwasher. This error informs about the incorrect operation of the flowing water sensor when the water pressure is exceeded. First of all, the water pressure in the tap is checked, and if necessary, the flow sensor is changed.

E21 - fault code of the dishwasher pump. The drain pump of the dishwasher is blocked, the water does not drain. This is due either to blockage of the pump or to its wear.

Note! On some Siemens dishwasher models, an E22 error occurs, sometimes interspersed with an E24 error. In 80% of cases, E22 is associated with a clogged filter located at the bottom of the washing chamber. And very rarely appears with a pump malfunction.

E24 - error code informing about the lack of water drain. This can happen for one of the reasons:

  • kinked drain hose;
  • clogged drain filter or drain hose;
  • clogged sewer.

Error codes related to water heating and sensors

Now consider the error codes for Siemens brand dishwashers that inform you of more complex problems.

  • E1 - error code that occurs when the water overheats or is not heated. Most likely, the cause is a malfunction of the heating element. The triac triac on the control module may also fail. Least of all, an error in heating the water occurs when the pressure switch or the inlet valve fails.Siemens dishwasher errors
  • E2 - the temperature sensor does not work (NTC sensor). This sensor in Siemens dishwashers is located inside the heater; replacing it is not so difficult if you know how to disassemble the dishwasher.
  • E4 - error code informing about the malfunction of the stream switch. This switch is located under the heater, its task is to distribute water in the rocker arm. The cause of the error can be either a clogged switch or a breakdown in the engine that controls the switch.
  • E6 - error code of the malfunction of the water turbidity sensor (Aquasensor). The aquasensor controls the turbidity of the water during the initial rinse of the dishes. Thanks to this sensor, the number of rinse cycles can be reduced. It is located next to the heating element.
  • E9 - fault code of the heating element. This error is typical for dishwashers with flowing heating element. It is necessary to check the unit with a multimeter and, if necessary, replace the heater with a new one.
  • E11 - error code that occurs when the dishwasher is operating without heating the water. This suggests that you need to check the temperature sensor, wiring, or the electronic board.
  • E14 - error code associated with incorrect operation of the water flow sensor. The dishwasher can work. In this case, a professional diagnosis of the dishwasher is required. Read about self-repair in the article. Siemens dishwasher repair.

    Important! Error code E18 is the only one that does not require any action. On the contrary, you need to wait until the dishwasher completes its work itself, while you can not turn off the power.

  • E27 - error code informing the user about a decrease in voltage in the electrical network. Most often, such an error occurs when the network is overloaded in the evening. In this situation, you need to check the voltage in the network, and for the normal uninterrupted operation of the unit to put a voltage stabilizer, which can save the car from repair.

So, there are not many codes for malfunctions in a Siemens dishwasher. The reasons for some of them are similar, so you need to be careful when identifying a malfunction, and in case of difficulty contact a specialist. Otherwise, you can not fix the car, but break it.
