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.
How to fix error f17
We should immediately warn you that in some modifications of washing machines (Bosch Maxx 5, Bosch Maxx 7) this error may be indicated by code E 17. We already know what this means, we just need to figure out how to correct the situation. First, let's perform actions that every consumer can do - check the supply valve, clean the filter and the hose itself.
If after this the error disappears, the problem is completely eliminated. But what to do if the signal resumes? There is only one thing left to do - continue to look for the problem. Let's move on to checking the internal elements.
Water intake valve
Before carrying out the test, turn off the water and disconnect the Bosch washing machine from the electrical network. We disconnect the hose from the inlet valve, substituting a container in advance into which the remaining water inside will drain. Remove the top cover of the washing machine and disconnect the connectors from the valve coil. We unscrew the screw, remove the valve, and inspect it for malfunction or blockage.
We install the element in the reverse order. If, when checking the car, the error code f17 clears, the problem is solved.
Pressure control sensor
This is a pressure switch that is responsible for filling the tank and sends the necessary information to the control module, after which the washing process is activated. If the sensor fails, it begins to give false readings or stops working completely. To fix the problem, remove the top panel of the Bosch washing machine, loosen the clamp, and disconnect the sensor hose.
To check the pressure switch, insert the tube and start blowing into it. If there are no characteristic clicks, the element must be replaced with a new analogue - repairing a failed sensor will not yield anything.
Control unit module
It has already been said that such a block receives a command to start the work process of washing, rinsing or spinning the laundry. If water gets on the module elements, or a voltage drop occurs in the network, the module may well fail. In this case, the Bosch washing machine faithfully issues an error signal f17.
To fix the problem, you should inspect the control board. Contacts will have to be repaired by soldering, burnt out elements will have to be replaced. As an additional measure, it is recommended to inspect the wires going to the pressure switch and inlet valve. If damage to the insulating layer is detected, we change the wiring.
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:
- The filling valve has failed;
- The pressure switch is broken;
- The control module has failed;
- Damage to the wiring between the above elements.
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
Problems with your Bosh washing machine that are associated with water intake from the water supply can be prevented using preventive measures.
These include:
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.
What does error f17 mean?
When you turn on the washing machine and for some time you do not hear the noise of water being drawn into the tank, signal f17 appears on the unit screen. Service center technicians explain this error simply - the time allotted for water collection has been exceeded.
Some consumers are sure that fault code f17 indirectly refers to the washing machine, but we recommend refraining from jumping to hasty conclusions.
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.
