On a Bosch washer with i-DOS, automatic detergent or softener dosing can be turned off even though the reservoirs are filled. Bosch manuals show separate dosage strengths and a deselected state, while program tables define where automatic dosing is available. Controls differ by generation, so the exact model manual is essential.
Check detergent and softener separately
Supported panels provide independent settings for the detergent and fabric-softener reservoirs. High, medium, and low refer to dose strength; the off or deselected symbol means that reservoir will not dose automatically. Do not assume one illuminated i-DOS indicator controls both liquids.
Program compatibility comes next
Some wash programs allow detergent dosing but not softener, while others may require manual product. Review the program table and make the selection before Start. Powder detergent belongs in the approved manual compartment, not an i-DOS liquid tank.
Safe user checks
- Confirm compatible liquid product is above the minimum level.
- Verify the intended reservoir is selected at an allowed strength.
- Choose a program marked as i-DOS compatible.
- Clean the system only by the model’s published procedure.
E:10 changes the service path
Bosch identifies E:10 variants as a blocked intelligent-dosing pump condition. The official guidance allows deactivating automatic dosing until the issue is resolved and directs model-specific cleaning or support. Do not dismantle the dosing pump, blow through tubing, or apply electrical power outside the assembled machine.
Model and observation notes
Bosch uses i-DOS names and symbols differently across markets and model years. The cited manual demonstrates the setting logic, while the exact washer manual controls the procedure. Confirm the full E:10 suffix if a code appears because Bosch groups several intelligent-dosing pump variants. Do not assume a general detergent light means the same thing. If manual dosing works on an allowed program while i-DOS does not, report that contrast. If neither path receives water, the issue may be a broader supply problem. This scoped comparison gives support better evidence without exposing pumps, valves, or concentrated detergent tubing.
For Bosch washer i-DOS not dispensing, record when detergent or softener is not drawn from i-dos reservoirs occurs, the chosen cycle, and the current indicator state; compare those notes with Bosch guidance for supported bosch washers with i-dos automatic dosing before requesting parts.
