No matter how reliable and high-quality household appliances are, no one is immune from breakdowns. They usually happen suddenly. Do not panic - any technique can malfunction. In today's article, we will consider the following problem: the Bosch dishwasher does not drain the water and it is standing in the dishwasher. What to do in this case and for what reason does this situation arise?

Types of faults

Specialists identify two main reasons why the Bosch dishwasher does not drain the water and it remains at the bottom of the unit. The most common is a kink in the hose and blockages. You can deal with these issues on your own. But the second type of reasons is more serious. This is a malfunction of some parts and links of the Bosch dishwasher. It can not drain water because of the pump and other elements. WhatLet's take a closer look at all the options.

Pay attention

Before we begin to find out the reasons why the Bosch dishwasher does not drain the water, it is worth emphasizing one point. All repair work must be carried out only after the machine is disconnected from the network. This should be done even if the damage is minor.

Dishwasher hoses

As we said earlier, one of the common causes of water stagnation is hose problems. If the hose that connects the dishwasher and the sewer is pinched or bent, the liquid simply cannot physically leave the device. As a result, the Bosch dishwasher does not drain the water. How to solve the problem? Just gently straighten the hose and connect the machine to the network. Next, you should restart the drain mode. The problem should be solved.

Filter

What other breakdowns of the Bosch dishwasher can cause water stagnation? One of the quite popular is clogging of the filter element. Each manufacturer (including Bosch) recommends rinsing dirty dishes from food residue before placing them in the machine. But many hosts ignore this rule.

So, the filter element becomes dirty with pieces of napkins, food particles and other debris. How to solve this problem? The cleaning element is located at the bottom of the device. It needs to be taken out, washed and put back in place. The device will work normally again.

Drain system

If your Bosch dishwasher won't drain, the drain may be clogged. So, some items of food and other debris can pass through the filter and form a blockage in the hose or at the junction with the sewer.

How to be in such a situation? You can clean the element with your own hands. This will require a container to drain the liquid. Carefully disconnect the hose and direct it into the container. If the water comes out with a strong stream, then there is a blockage at the junction with the sewer. If the liquid does not drain, the hose itself is dirty. You can rinse it with a powerful stream of water.

Pump

It happens that the pump itself becomes dirty in the dishwasher. Because of this, the equipment does not drain the water. In this case, you need to get to the pump (the instructions for the device will help you) and remove the blockage yourself. To do this, unscrew all the fasteners of the element and put things in order. After removing the blockage, it is worth checking whether the pump impeller rotates easily. This can be done with a pencil, stick or other object. Never touch the impeller with your hands. After all the elements have been cleaned and connected back, you can start the device and check its operation. But it also happens that the dishwasher still does not drain the water. What to do? Let's look at a few more typical faults.

Pump failure

This element is responsible for draining fluid from the system. And if the pump burned out, then this process will not occurwill. Unfortunately, this item is not recoverable. The pump is completely replaced with a new one. Usually it costs about two thousand rubles.

Aquasensor failure

The Bosch dishwasher is equipped with a special aqua sensor. What is this element? This is the part that controls water pollution. It must be said that the error of the E6 aquasensor on the Bosch dishwasher may not always be displayed on the screen, but it is stored in the memory of the control unit. How to solve this problem? You can try flushing the system with antiscale. If this does not help, only installing a new aquasensor will solve the situation.

Faulty pressure switch

What is this element? It is a water level sensor. Often it is his merit that the Bosch dishwasher constantly drains water or does not drain at all. The sensor tube is connected to the tank so that the liquid, when drawn into the latter, is at the same level with the water in the tube. The pressure switch measures the pressure in the upper part and thus determines the water level in the tank. If the element is faulty or there is a crack in the tube, false data will come from the pressure switch. The system will assume that the water has already been drained, and will not pump it out or will do it indefinitely.

Program module

He is a kind of brain of the dishwasher. It is the software module that analyzes the washing cycle, and also sends signals to the actuators (electric heater, pump, inlet valve and other elements). Whenfailure of this module, commands may not be sent in full or not sent at all.

How to solve the problem in this case? In order for the dishwasher to work again, a flashing of the software module will be required. If this does not help, you can state the physical breakdown of the block itself. The only way to solve the problem is to replace the module with a new one.

How to enable forced drain?

What to do if the machine does not drain the water? You can apply forced flush. To do this, perform a number of specific manipulations.

If this is an old Bosch dishwasher, then a ratchet switch is installed in it. Turn the switch clockwise to open the corresponding valve.

If this is a more modern model, you will have to reset the programs and close the door here. The outlet valve will then open automatically. If this does not happen, you should additionally hold the start button for three seconds. As a result, the liquid will leave the system.

Common mistakes and their interpretation

What does the code "E1" say? This error indicates a heating problem. In this case, you can state a malfunction:

  • water level sensor;
  • protective thermostat;
  • water flow sensor;
  • TENA (the reason is the lack of resistance);
  • control module (reason - no power to the heater).

Sometimes the "E3" code lights up on the Bosch dishwasher. What does it say?This error is related to filling the system with water. So, the Bosch dishwasher can slowly fill in liquid or not fill it at all. In this case it could be:

  • dishwasher inlet filter clogged;
  • faulty drain pump;
  • Faulty Aquastop valve or water level sensor.

"E27". This error indicates a low voltage in the network. Happens often. You should check the voltage at the outlet. Typically, such an error occurs during peak loads on city power networks. In such a situation, the best way out is to install a special voltage regulator.

Conclusion

So, we found out why the Bosch dishwasher does not drain the water and there is water in the dishwasher. As you can see, there are several reasons. Solutions are also different. Therefore, it is important to accurately determine the nature of the breakdown, and then follow the recommendations.
