Bosch Washer Error Code E:24

E:24 means the pressure sensor is producing a voltage level outside its normal operating range. The pressure sensor monitors water level inside the drum and communicates that information to the control board via an electrical signal. When that signal falls outside expected parameters, the washer stops and displays E:24. The fault points to either a defective pressure sensor or a problem in the wire harness connecting it to the control board.

It is not recommended to run the washer while E:24 is active. The pressure sensor is responsible for monitoring water levels, and if it is malfunctioning, the machine may not regulate water intake properly. This could lead to overfilling or erratic cycle behavior. The washer should be diagnosed and repaired before resuming normal use.

A reset may temporarily clear the code, but it will return if the underlying problem is not corrected. The error is triggered by an out-of-range voltage signal from the pressure sensor, which is a hardware issue rather than a software glitch. Resetting without repairing the sensor or wiring will cause E:24 to reappear as soon as the washer attempts to read water level again. A proper repair of the sensor circuit is required for a lasting fix.

Start by running the built-in diagnostic test P8, which evaluates the pressure sensor circuit. Inspect the wire harness and connectors between the sensor and the control board for damage, corrosion, or loose terminals. If the wiring is intact, the pressure sensor itself likely needs to be replaced. Also check the air pressure tube connected to the sensor for kinks, cracks, or blockages.

Repair costs depend on which component has failed. A replacement pressure sensor typically falls in the range of $20 to $60 for the part alone. If professional labor is involved, total repair costs can range from $100 to $250 depending on your location and service provider. If the issue is simply a loose or corroded connector, the fix may cost little to nothing beyond your time.
