The meaning of the e04 error code in Siemens washing machine

Siemens dishwasher can issue the E04 system error if the flow sensor fails. In addition, there are situations when the code appears if the nozzles are not working properly. It relates to the blockage or high rigidity of water, used for washing dishes. In this case, the jets cannot safely pass through the holes of the sprinkler. In turn, this leads to the technique breakage.

The situation in which water is poorly supplied to the device is not critical. You can eliminate it completely even at home.

How to fix the E04 system error?

Before repair works, you need to make sure that the problems are real. In some situations, a fault code may occur during system malfunctions.

First of all, try to reset the error. For this:

  • turn the unit off and unplug it;
  • wait for about 10 minutes;
  • start the dishwasher again.

If the fault code disappears, the dishwasher is completely in order. However, if the Siemens dishwasher issues the E04 code again, you should start troubleshooting.

To do this, clean the sprinkler. The essence of the procedure is as follows:

  • removal of the rocker from the seat;
  • rinsing under the running water;
  • cleaning nozzles with a toothpick.

Experts recommend using special dishwasher salt as the prevention of the E04 error. It reduces water hardness so that the limescale on the parts and components do not form.

The nozzle is cleaned, but the error occurs again

In this case, the problem lies in the flow sensors. Their purpose is to control the amount of water entering the nozzles. In some Siemens dishwasher models, this element is installed instead of a standard pressostat. This sensor sends a command to the control module to stop feeding. Thus, water gaining stops.

When choosing a sensor for replacement, be sure to consider the brand and model of the dishwasher. All original components are suitable only for a specific device.

To avoid breakages and the E04 code appearance on the display, take care of the dishwasher timely. Specialists recommend cleaning filters and other components at least once a month. Also, use special agents, which prevent scale formation.
