What should I do if the error E04 is displayed in the Bosch dishwasher? It is necessary to determine the value of the code - it indicates the failure of the flow sensor, because, for example, there was a blockage. Our article will help you to make detailed decoding, and also will tell you how to fix the problem.
If the dishwasher stops operation and displays incomprehensible symbols on the display, the system notifies the user of the problem by using the self-diagnosis function.
What does the DTC mean?
The dishwasher can show error E 04 when the flow sensor breaks down, and if the injectors fail. Due to clogging or high water hardness, jets do not pass well through the holes in the sprinkler, which leads to the braking of the PMM.
Water does not go in well, but this position is uncritical, so you can try to eliminate the damage yourself.
How to fix the situation
First you have to check whether the fault is actually occurring, or it is a failure in the system. Try to reset the code E04:
- disconnect the Bosch dishwasher from the mains;
- wait 10-15 minutes;
- please try restarting.
If the icons have disappeared and no longer appear, it means everything is in order. But if the machine again displays an error on the screen, then you need to take action.
What to do? To clean the sprinkler:
- Remove the rocker from the seat.
- Rinse under the pressure of water.
- Clean the nozzles (holes) with a toothpick.
Use a special salt for dishwashers. It allows you to reduce the hardness of water and prevents the formation of calcareous deposits on the parts.How to choose a tool, read in a separate article.
The parts are cleaned, but the trouble code appeared again? Then replace the flow sensor. It is designed to control the amount of water that enters the nozzles. Part is installed in some models of "Bosch" instead of the usual pressure switch. From the sensor, the stop signal arrives at the control module, which instructs the user to stop the water intake.
We recommend choosing a spare part for replacement to focus on the make and model of your dishwasher. Because all components are original.
You can avoid such breakdowns ifto take care of machinery in a timely manner. At least once a month, clean the filters and other parts. Use tools to avoid the appearance of scale.
