Error E17 or F17 in a Bosch washing machine

Causes of error F17 (E17) on a Bosch washing machine

Error F17 (E17) on the display of Bosch washing machines occurs when there is no water supply to the tank. The user of household appliances notices the following:

• When the unit is turned on: the hatch door is locked, but no water is drawn in,
• During the washing program, the Bosch washing machine takes a long time to fill with water,
• During the rinsing process, the washing machine does not fill the tank with water.

New models of Bosch washing machines display codes with the letter E at the beginning, for older modifications it is customary to display with F.

Bosch models without a display notify of the problem with spin speed LEDs. In case of fault F17, the "Stop after rinsing" (No spin) light and the upper spin speed indicator (800 or 1000) flash simultaneously.

What can you check yourself?

If your Bosch washing machine displays error code F17, you can try to fix the error yourself:

• Self-draining of water from the tank. Due to incorrect connection of the drain, water leaves the tank by gravity, so the device constantly adds water.
• There is no water in the water supply. Open the tap in the bathroom or kitchen, perhaps your water has been turned off.
• The water supply tap to the washing machine is closed. It is necessary to check the position of the shut-off valve, it may be closed.
• The inlet hose that supplies water to the tank is pinched or twisted. Check the water supply hose and straighten it if necessary.
• Insufficient water pressure. This can happen when the pressure in the water supply is low.
• The intake valve filter is clogged. This is a mesh that over time becomes clogged with salts, scale, etc. It needs to be cleaned.

If the checks did not produce results, then the display of the error code on the Bosch machine is associated with hardware problems.

Repair of Bosch washing machine with error F17

Here are the most common problems that cause the E17 error:

• The inlet valve, which ensures the flow of water into the equipment, has failed. The valve includes a housing, a membrane and an electromagnetic coil. It is often the coil that fails. The valve needs to be replaced.
• The pressure switch (water level sensor) that measures the amount of water in the machine is faulty. The sensor tube may have come off or become clogged, the pressure sampling chamber of the level sensor may have become clogged. The sensor itself may have broken. The Bosch machine does not fill with water. The faulty part must be repaired or replaced.
• Control unit failure. The tracks, microcircuit elements or contacts have burned out in the intake valve control circuit. The technician will replace the parts, solder or replace the damaged contacts. Sometimes a complete replacement of the control module is required.
• Board firmware failure. The self-diagnostic system displays error F17 or E 17. Water is not poured in, the washing process does not start. It is necessary to remove the top panel, remove the unit, inspect, and then reflash or replace the part.
• Wiring, contacts faults. If the wiring is damaged, the signal does not reach the intake valve, and the unit freezes with an error. The specialist restores the wiring and/or solders the contacts. In some situations, it is necessary to install a new cable and/or contact group.

Any Bosch washing machine service begins with disconnecting the equipment from the power supply, disconnecting the hoses, and then proceeding to disassemble the equipment.

It is better not to deal with the E17 or F17 error yourself, contact professionals. The Bosch washing machine service center technician will quickly identify the cause of the malfunction and eliminate the breakdown, providing guarantees for services and installed components.
