Bosch Washer Error Code 29

Error 29 means the washer's flow sensor detected no water entering the drum during a fast measurement check at the start of a fill cycle. The machine stops to prevent running without water. The cause can be as simple as a closed water tap or as involved as a failed inlet solenoid valve or pressure sensor.

A reset may clear the error code temporarily, but the code will return as soon as the washer attempts to fill again if the underlying cause has not been resolved. You should diagnose and correct the water supply or component issue before relying on a reset. Resetting is only useful for confirming whether a transient condition, like a momentarily low water pressure event, was the trigger.

If the fix is simply cleaning the inlet filter or opening a tap, there is no parts cost involved. Replacing an inlet solenoid valve typically runs between 40 and 120 dollars for the part, plus labor if a technician is involved. An aqua stop hose assembly generally costs between 30 and 90 dollars. A pressure sensor replacement is usually in the 25 to 75 dollar range for the part alone. Total repair costs with professional service can range from 100 to 300 dollars depending on the component and your location.

Start by confirming the water tap behind the machine is fully open and the supply hose is not kinked. Next, disconnect the hose and clean the inlet filter screen, which is a small mesh insert at the valve connection point. If water supply is confirmed normal, inspect the aqua stop hose assembly and the inlet solenoid valve. If those components test faulty, they will need replacement.

No. Error 29 means the machine halted because it could not confirm water was entering the drum. Running a wash cycle without adequate water can damage the drum bearings, heating element, and other internal components. The machine should remain out of service until the fault is resolved.
