A drum icon with a water droplet on a supported Bosch washer means drum cleaning is required. It is a maintenance reminder, not a code that identifies a failed pump, heater, or motor.
Prepare the washer
Remove every garment and check the drum for loose objects. Select the Drum Clean program named in the owner’s manual. Follow the manual for any allowed cleaner and dispenser compartment; the permitted product and dose can depend on the model.
Bosch recommends its washer cleaner periodically to remove greasy residue and specifically advises against using vinegar or citric acid because those acids can attack rubber parts.
What the cycle is meant to remove
Low-temperature washing, excess detergent, and retained moisture can leave a film on the drum and surrounding water path. A dedicated maintenance program uses an empty drum and a programmed temperature and motion pattern. Clothing prevents the cycle from reaching the surfaces as intended and can expose fabric to a cleaning product.
After Drum Clean
- Wipe accessible moisture from the door seal without pulling it out of position.
- Clean the detergent drawer using the removable-part instructions for the model.
- Let the door and drawer air dry when safe.
- Review detergent dose if foam or residue returns quickly.
If the icon stays on
First confirm the Drum Clean cycle completed rather than being canceled. If the icon remains after a complete, correct cycle, or the washer cannot start the program, note any accompanying code. Do not enter a hidden service menu to reset the counter. A drain, heater, sensor, or control problem that interrupts maintenance needs Bosch support.
Use the reminder to choose the right cycle
The drum-with-droplet symbol is a maintenance prompt on supported Bosch washers, not a universal error icon. Confirm the symbol against the model manual before interpreting it, especially if another character or audible warning appears at the same time.
Remove laundry and select the model’s named drum-care program. Follow Bosch guidance for temperature and cleaning product; do not combine chlorine bleach, descaler, vinegar, or another cleaner unless the manual expressly permits it. If odor or residue remains after maintenance, inspect the user-cleanable seal and dispenser areas rather than assuming the reminder sensor has failed.
