Troubleshooting error E18 in a Bosch washing machine

The owner of a Bosch washing machine may encounter error E18 during operation. In this case, do not be upset. After all, any malfunction can be eliminated. Let's try to figure out what this code means and what actions to take when it occurs.

Reasons for the error

Code E18 in Bosch washing machines indicates that waste water does not drain from the tank. This error may be indicated by different codes depending on the model of the washing machine. The E18 code is also identical to F18 and D02.

Water may not drain from the tank for the following reasons:

• The drain hose is not connected correctly;
• The water drain hose is bent or pinched;
• The drain system is clogged. It includes pipes, filters and pumps;
• The pump has failed;
• The water level sensor is broken;
• Damage to the control module of the Bosch machine.

Clearing the blockage

If from the tank of a Bosch washing mashine water does not drain, then the first thing to do is shut off the water supply. Then turn off the washing machine.

To find the cause of the breakdown and eliminate error E18, you need to drain all the water from the washing machine tank. This can be done using a small drain hose.It is located near the drain filter. To find it, you need to open the small plastic door, which is located at the bottom of the washing machine.

There is another way to drain the remaining water in the tank. To do this, you need to dismantle the drain filter. However, to do this, you should place a container under the machine, and also place rags under it. The filter must be inspected after unscrewing. It was probably because of this that the drainage system in the Bosch washing machine became clogged and error E18 occurred. If dirt and debris have accumulated in the filter, it must be cleaned and then rinsed thoroughly.
Next you should inspect drain hose Perhaps he went too far. After draining the water from the tank and inspecting the filter, you can continue to search for the cause of the E18 code in the Bosch washing machine. It is necessary to take the equipment to a place where it will be convenient to work with it.

You also need to prepare all the necessary tools.

Next, to resolve error E18, you need to perform the following steps:

1. remove the bottom plastic panel and unscrew the fasteners located under it;
2. remove the clamp that holds the cuff using a screwdriver.
3. remove the lock device;
4. disconnect the chip with wires connected to the lock;
5. remove the washing powder cuvette and then unscrew the bolts under it;
6. carefully remove the control panel of the Bosch machine;
7. move the front part of the body to the side;
8. find the drain pump. It is located at the bottom right;
9. loosen and remove the clamps on the pipes connected to this pump;
10. check the pipes. If there is debris in them, remove it.

How to repair a pump

The next step is to check machine drain pump. To do this, you need to release the latches and disconnect it from the snail. After dismantling the snail, the impeller will be visible - the rotating element of the pump. Hair wound around it can prevent the impeller from rotating freely. All this leads to the pump not functioning.

Drain pump

It should be noted that the problem may not only be in the damaged impeller. The electrical part of the drain pump of the Bosch equipment may also fail. In any case, the broken part should be replaced with a new one. This work should not cause any difficulties.

Next, to eliminate the E18 error, you need to do the following:

• c connect the pump to the snail;
• using new clamps, connect the pipes to the pump.
• connect the plug with the wiring;
• secure the pump to the body of the washing machine;
• completely assemble the Bosch machine;
• check the operability of the equipment.

If the drainage system was in good working order, then the E18 error appears due to problems with other components of the machine. Water may not drain due to a faulty water level sensor. If it is faulty, the washing machine may stop working with a full tank. This element is checked using a multimeter.
The pressure switch in Bosch brand machines is located in the upper right corner of the case. It is not difficult to get to it. To do this, remove the top cover. First, you need to check the condition of the tube from the sensor. It is also important to check the wiring contacts connected to the pressure switch. Only then can you remove and check the sensor. If this part is faulty, it must be replaced with a new one.

Control module failure

If this element is faulty, absolutely any error can appear, not just E18. After all, it is responsible for the functioning of the washing machine as a whole.
