Bosch Washing Machine Error Code E27 – Meaning and Possible Fixes
Bosch Washing Machine Error Code E27
If your Bosch washing machine displays Error Code E27, it usually indicates that the appliance has detected a problem with the pressure sensor or water level monitoring system.
Bosch washing machines use a pressure sensor to measure the amount of water inside the drum during a wash cycle. If the appliance cannot correctly detect the water level, the control system may stop the cycle and display the E27 error code.
On some Bosch washing machine models this error may also appear as F27.

What the E27 Error Means
The E27 error code generally indicates that the washing machine is unable to read the water level correctly. This is usually caused by a fault with the pressure sensor or the small hose connected to it.
The pressure sensor helps the washing machine determine when to fill, wash and drain water during the cycle. If the sensor sends incorrect readings or fails to respond, the control system may trigger the E27 error.
Common Reasons This Error Appears
Faulty pressure sensor
The sensor responsible for measuring water levels may be damaged or malfunctioning.
Blocked pressure hose
The small hose connected to the pressure sensor may be blocked with detergent residue or debris.
Electrical fault
Loose wiring or connection problems may prevent the sensor from communicating with the control board.
Control board issue
The electronic control system may not be processing sensor signals correctly.
Safe Checks You Can Try
Before contacting a technician, there are a few safe checks you can perform.
Restart the washing machine

- Switch off power at the wall socket or circuit breaker.
- Wait several minutes.
- Restore power and start a new wash cycle.
Run a maintenance wash
- Run an empty hot cycle with a washing machine cleaner.
