Interpretation of error F17 (E17) on a Bosch washing machine: causes of malfunction, solutions

Decoding error F17 (E17)

Error F17 (E17) means that the washing machine was unable to draw water within the allotted time. In reality, it looks like this: the machine is plugged in, the mode is selected, but water does not flow into the machine. It is worth considering that there is also no sound of water supply. Due to a prolonged lack of water, the system cannot start or continue the washing process.

On a Bosch washing machine without a display, the 800 or 1000 rpm indicator and plus the “Rinse” light will light (blink) simultaneously.

Causes and solutions to the problem

If error code F 17 is displayed on the Bosch washing machine display, this means that the time for filling the tank has been exceeded. The fault code may appear both at the beginning of the wash cycle and before the rinse cycle.

Note! For some Bosch washing machines, error F17 is indicated as code E17.

You’ve figured out what the error means—now you need to understand how to fix it. To do this, let’s look at the reasons for the appearance:

How to correct the situation if actions did not help? Continue troubleshooting.

What caused the malfunction

Let's consider the reasons that may cause a malfunction:

Lack of water. You need to check if there is water in the tap. It is possible that the water supply has been turned off or is blocked.
Shut-off valve closed. It is necessary to check the shut-off valve that shuts off the flow of water into the washing machine. It may not have been opened before the wash started. Water does not flow into the washing machine, which causes the error.
The shut-off valve is not fully open. This results in a long time to collect water, which causes an error. The shut-off valve must be fully opened.
Weak water supply. The washing machine does not have time to draw water and displays an error.
Kinked, tangled or pinched inlet hose. This is an obstacle to the supply of water to the washing machine, which also causes error F17 (E17). It is necessary to straighten the hose for unimpeded flow of water.
Clogged filter mesh. Often, the filter mesh, located at the point where the inlet hose is connected to the washing machine itself and protects it from small particles contained in tap water, becomes clogged. The washing machine will not draw water well and display this error. It is necessary to remove and clean the filter: put it in a solution of citric acid for several hours, and then put it back in place.
Failure in the control unit. Quite often, failures occur in the control unit. It is necessary to unplug the washing machine for 15-20 minutes and then turn it on.

The above methods will help you troubleshoot the error yourself.
In all other cases, it is better to contact a specialist, since the breakdown occurred in the internal parts of the washing machine. See also -

Causes

As mentioned above, code E17 in Bosch washing equipment indicates that water is not entering the tank. Therefore, the washing process may not start. For some washing machine models, this malfunction corresponds to error F17. This is what the manufacturer intended. If the Bosch washing machine does not contain a display, then this error can be determined by two indicators that are lit: rinse and spin at 1000 rpm. However, deciphering the E17 code is not enough. You should find out why the error occurred.

There are several of them:

But when looking for the cause, you should first check the simplest options. First you need to check if there is water in the tap. Perhaps it is missing. You should also check the water supply tap. It is located in the place where the inlet hose is connected to the water supply.

How to clean the mesh filter

Let's look at a step-by-step method to fix the problem in the filter mesh. Blockage is the most common cause of error. You can get rid of the blockage in this way:

turn off the power to the washing machine;
close the water supply tap to the washing machine;
unscrew the end of the hose that is attached to the machine itself;
if there is water left in the hose, then it is necessary to prepare a container for this water;
remove the mesh and rinse it thoroughly;
screw the hose back;
then unscrew the hose from where the water enters the washing machine;
we get rid of dirt, if there is any, of course;
screw the hose back.

So, if you turn on the machine and do not hear the sound of water being drawn for a long time, and error F17 appears on your display, this means that the water supply time has been exceeded. Let's look at the causes of the malfunction that require repair.

Causes of malfunction and ways to eliminate them

Error E17 - what is it? Stopping the wash cycle due to lack of water supply does not always indicate a complex Bosh failure.

In some situations, the problem can be solved quite simply , without requiring disassembly of the washing machine and calling a technician. In rare cases, a malfunction of the washing machine may be caused by a one-time power surge or a coincidence.

In this case, a simple reboot can help - unplug the washing machine for 20-30 minutes (pull the plug out of the socket), and then turn it on and start again. If the reboot does not help, move on to diagnosing the failure.

Self-draining during washing

Self-draining is characterized by the intake and immediate discharge of water . This situation indicates a violation of the Bosh connection. This can happen either with a recently installed washing machine or with an old one that has been moved or moved to a new location.

When installing the machine, the drain hose must be raised above the level of the tank. This point is stated in the instructions for the washing machine. If the hose simply spreads along the floor, the collected water will flow out spontaneously. As a result, the tank remains empty, and after a certain time the washing machine issues an alert E17 (F17).

Weak pressure

The Bosh washing machine produces water, but the process is very slow. It is necessary to make sure that there is sufficient pressure in the water supply system . You also need to see if the tap that shuts off the water supply to the washing machine is fully open.

Clogged water supply filter

If the filter is clogged, the Bosh washing machine may draw little water or not draw it at all. Functionally, a filter is a mesh that is designed to capture and retain small fractions that may be in tap water.

If water does not flow to the washing machine, you need to clean the filter. To do this, perform the following steps:

Turn off the water supply valve to the device.
Pull out the washing machine so as to gain convenient access to the rear wall.
Place a rag on the floor from the back wall and place a bucket.
Unscrew the plastic nut, disconnecting the hose.
Carefully remove the mesh.
Clean in water.
Reassemble the assembly in reverse order.

When performing a test run of the washing machine, you must ensure that the connection is tight.

The device does not draw water

If the washing machine tries to draw water, but it fails, you need to make sure that there is water in the water supply. This is very easy to do - you just need to try opening the tap in the bathroom or sink. If there is no water in the system, washing will have to be postponed.

Another possible reason is turning off the water supply tap to the washing machine. Make sure that the shut-off valve is turned to the “ON” position .

A more rare, but quite possible situation is a severe bending/squeezing of the hose. It is advisable to check its condition along its entire length, including behind the furniture.

Inlet hose clogged

In order to check the condition of the inlet hose, it should be disconnected from the washing machine and from the water supply. Remove it after the water supply to the device is turned off.

Fill valve problem

The fill valve has a rather complex structure - it consists of an electromagnetic coil, a membrane and a housing.

To access the valve, the washing machine will have to be partially disassembled. If the unit fails, the valve is replaced with a new one.

The valve in Bosch washing machines can be two sections - one of them is designed to draw water for washing, the other for rinsing. Depending on which section is out of order, the washer may either not rinse or not start washing.

Breakdown of the pressure switch

Pressostat is a part that measures the water level in the washing machine tank . If the sensor fails, it does not provide objective information to the control module, and water is not drawn. The solution to the problem is to repair or replace the pressure switch.

Control unit malfunction

If the control unit fails, the Bosh washing machine does not draw water. Repair of the module is carried out by partially disassembling the washing machine and removing the unit.

In most cases, repairs can eliminate the damage. But if the module is badly burned out, it is replaced with a new one .

Wiring irregularities

If the wiring in the washing machine is defective, various malfunctions can occur. One of them is the lack of water supply. For diagnostics, the washing machine is partially disassembled to check the condition of the wires and terminals.

Inlet valve faulty

In order to check the valve, you need to turn off the water and disconnect the washing machine from the electricity. Next, you need to prepare a container to drain the water and disconnect the hoses from the inlet valves. You need to unscrew two screws and remove the top panel. The next thing to do is remove the clamps and unscrew the fixing screw. Remove the valve and check if it is clogged. Perhaps there was some damage on it. Check everything and reinstall the valve. If everything goes well, then error F17 should disappear.

Water intake valve

The problem looks like this: the user turned on the program, but no water flows. If the washing machine is equipped with a display, then F17 appears on the display. If there is no screen, the speed and rinse lights blink. It is worth noting that in some models, for example Bosch Maxx 5, Maxx 7, this error is designated as E17. This is how the washing machine signals that there is not enough liquid required to start the program.

There may be several reasons for this malfunction. First, you should check the connections of all hoses and valves; they can cause a fault code to appear, and also rule out a failure of the electronic controller by turning off the machine for half an hour.

If there is water in the system and its supply valve is open, all hoses are correctly connected, and the filters are cleaned, then the next most common cause of failure may be the inlet valve.

In this case, you need to disconnect the machine from the electrical network, turn off the water supply and prepare a container for liquid, and then check the valve for serviceability:

disconnect the hoses from the water intake valves;
remove the top cover by unscrewing the bolts from the back;
disconnect the connectors from the valve coil;
bend the clamps and remove the hoses;
unscrew the fixing screw and pull out the valve;
inspect it for blockages or damage;
After elimination, perform installation in reverse order.

The pressure switch is broken

A pressure switch is a pressure sensor that controls the amount of water in the tank. To get to the pressure switch, you need to remove the top cover of the machine. To check, you need to disconnect the clamps and hoses from it, insert a tube and blow into it. If there are no clicks, you must disconnect all connectors and remove the broken part. It cannot be repaired, so if you find the cause of the breakdown in it, then you need to replace the pressure switch with a new one.

Malfunction in the control module

The control module is one of the main parts of the washing machine, a kind of brain that gives commands to start washing, spinning or rinsing. If moisture gets in or a voltage drop occurs, some elements of the module may fail. To check the control board you need:

turn off the power to the washing machine;
remove the top panel (cover);
take out the dispenser (powder tray);
Unscrew all the screws holding the front panel.
remove the front panel;
disconnect the board from the front panel and inspect it.

Burnt-out capacitors, resistors, diodes, microcircuit tracks, oxidized contacts - all this can be replaced or soldered. If the microprocessor is faulty, the control module must be replaced.

Causes

Coding E 17 (in the newest models - F17) means that the time allotted for filling the washing machine tank with water has expired. In this case, there are no interruptions in the power supply, the start button for the selected mode is pressed, but the flow of liquid does not begin, as evidenced by the absence of the characteristic “murmuring” sound. The system reacts to a prolonged absence of water, cannot start or continue the washing process and signals this. The most common reasons why error e17 appears on the display include:

Lack of water supply. Identified by opening any tap in the apartment, the washing process is started again or resumed after water appears.
Complete or partial shutdown of the valve on the water supply system to the machine. Before starting the wash, the shut-off valve must be fully open, otherwise water either does not flow at all or does not have time to fill the tank in the allotted time.
Low pressure in the water supply. Low pressure does not allow the machine to fill the tank with water in time.
Problems with the inlet hose. This element of the water supply to the machine must be in a straightened state and clean from the inside: crushed or twisted places prevent the passage of liquid.
The mesh filter is clogged. The part located where the inlet hose is fixed to the body of the washing machine and is designed to purify tap water from small particles periodically becomes clogged.
Internal faults in the Bosch washing machine, including breakdown of the inlet valve and pressure sensor (pressostat).

A failure can also occur in the control unit. Sometimes it helps to fix the problem by disconnecting the device from the power supply for 15-20 minutes and then turning it on. Otherwise, the unit needs to be repaired.
