Bosch Washer - Er:19 Error Code

The pressure sensor is reporting invalid or inconsistent water level readings.

Meaning

The pressure sensor is reporting invalid or inconsistent water level readings.

The Bosch Er:19 error code indicates that the washer’s pressure sensor (also known as the water level sensor) is sending inconsistent, impossible, or rapidly fluctuating readings to the control module. Legacy Bosch washers rely on a pressure chamber and thin rubber hose to measure water level. If the hose becomes blocked, the sensor becomes contaminated, or the wiring is damaged, the control board cannot determine the correct water level and triggers Er:19 to prevent overfilling, underfilling, or heating with insufficient water.
