How to Fix Bosch Top Load Washing Machine F8 Error
The F8 error code on a Bosch top load washing machine typically indicates a malfunction with the water level sensor or the pressure switch. This prevents the machine from accurately detecting the water volume, causing the cycle to halt for safety reasons.
Understanding the F8 Error
- The F8 error signals that the control board is not receiving a signal from the pressure switch, which monitors the water level in the drum.
- This is often caused by a disconnected or kinked air tube, a faulty pressure switch, or a loose wiring harness connection.
- In some cases, a clogged air chamber can prevent the sensor from reading the pressure correctly.
Safe Steps to Try Before Calling a Technician
- Perform a hard reset by unplugging the washing machine from the power outlet for at least 10 minutes to clear the electronic memory.
- Check the air tube connected to the pressure switch for any kinks, cracks, or blockages that might prevent air from reaching the sensor.
- Ensure the water inlet valves are fully open and the water pressure in your home is sufficient to fill the tub within the allotted time.
- Inspect the wiring connections leading to the pressure switch to ensure they are secure and free from corrosion.
Always disconnect the power supply and turn off the water taps before opening the top panel or inspecting internal components to avoid electrical shock or water damage.

Frequently Asked Questions
Can I fix the F8 error without replacing parts?
Sometimes, the error is caused by a loose wire or a kinked tube. If you clear the blockage or reconnect the wire, the machine may function normally without needing new parts.
Does the F8 error mean my pressure switch is broken?
Not necessarily. While a faulty pressure switch is a common cause, the error can also be triggered by a disconnected air hose or a communication error with the main control board.
Is it safe to continue using the machine with an F8 error?
No, you should not attempt to use the machine while the error is active. The machine cannot accurately measure water levels, which could lead to overflowing or damage to the heating element.
When should I call a professional technician?
If you have performed a hard reset and checked the air tube for blockages but the error persists, it is likely an internal component failure that requires professional diagnostic tools.
