But do not worry, because any problem is solvable. This can happen, for example, if an E18 error occurs in the washing machine manufactured by Bosch.

Decoding and Cause For E18 Error

Speaking of the Bosch technique instruction, the error is explained short and understandable. The E18 code that appears in the Bosch washing machine means that there is no drainage of water. And a user also notices that there is water in the tank. It seems like the appliance hasn’t even tried to start the drain.

In various Bosch washing machines models, a manufacturer shows the error by different codes. F18 and d02 faults are the identical ones.

What if the washing machine is not equipped with a screen? In this case, users discover an error due to the indicators located on the control panel. If there is no drain, the spin speed indicators for 1000 and 600 lit up. What reasons can affect the fact that the tank does not drain water? Let’s list the main of them:

  • violation of the rules of connecting the drain hose;
  • bend or clamp the water drain hose;
  • blockage of the drainage system (filter, nozzles, pumps);
  • pump failure;
  • the sensor that measures the water level in the tank is broken;
  • “brain glitches” of the washing machine, module malfunction.

If such an error occurs, the first thing a user should do is to close the water supply. Next, turn off the washing machine first with the button, and then from the mains. To carry out repairs and find the cause, you must also drain water from the tank. Do it through a small drain hose. It is located at the bottom of the appliance, next to the drain filter behind a small plastic door.

The second way to drain the water is to pull out the drain filter. But in this case, it is necessary to leave some rags on the floor or put a basin under the washing machine. Unscrewing the filter, at the same time you may check if it is the cause of the drain system clogging. If dirt, foreign objects, and hair have accumulated there, clean and rinse the part. Also, examine the drain hose for bending. However, it happens seldom, but even so, you need to check it, too.

Having drained water from the tank and checked the filter for blockage, start looking for another reason. To do this, pull the machine to a convenient place and prepare the tools (screwdriver and pliers), then:

  • remove the bottom plastic panel and unscrew the bolts;
  • using a screwdriver, remove the clamp that holds the rubber cuff;
  • unscrew the lock device;
  • disconnect wires from the lock;
  • pull out the cuvette for the powder and unscrew the bolts under it;
  • gently remove the control panel without pulling the wires;
  • remove the front of the case to the side;

  • at the bottom right, find the drain pump and the nozzles connected to it;
  • loosen the clamps on the branch pipes and remove them;
  • if there is no debris in the branch pipes, then the cause of this error is not blockages, but something more serious. We’ll tell about this further.

Pump and pressure switch repair

So, the washing machine is dismantled, the drain pump is almost in your hands. Pull it out and detach from the helix by opening the latches. Having removed the helix, you will see a rotating part of the pump, the impeller. You may see villi or hair that has wounded on the detail. It prevents free rotation. As the result, the pump does not work and plum is difficult.

Also, the impeller may be damaged, and the electric part of the pump may have burnt. In both cases, you have to replace the part. The installation of a new spare part should not cause difficulties. It is necessary to act in the reverse order:

  • connect the pump with the helix;
  • connect branch pipes to the detail, using new clamps;
  • connect a chip with wires;
  • fix the pump on the body;
  • assemble the washing machine and check how it operates.

If the drain system is in order, then the reason for the lack of drainage is in other units of a technology. Besides the pump, the draining process depends on the sensor functioning. It measures the water level. If the sensor is broken, then the device can “hang” with a full tank, so prepare the multimeter.

Pressostat in the Bosch washing machine is located in the right upper part of the case. Remove the top cover to access it. Before pulling out the part, check the integrity of the tube, coming from the sensor. Also, inspect the contacts of the wires connected to the pressure switch. Only after this, you can check the sensor and replace it if necessary.
