Bosch Washer - E10 Error Code

The i-DOS detergent dosing pump is blocked or restricted.

Meaning

The i-DOS detergent dosing pump is blocked or restricted.

The Bosch E10 family of error codes (E10, -00, -10, -20) indicates a blockage or malfunction in the i-DOS automatic detergent dosing system. Bosch washers equipped with i-DOS use precision pumps to dispense detergent and softener. When the pump cannot draw or dispense fluid—due to thick detergent, clogs, or dried residue—the washer displays E10 to prevent incorrect dosing and poor wash performance.

Symptoms

  • Washer displays E10 before or during a cycle
  • i-DOS does not dispense detergent
  • Detergent drawer remains full after cycles
  • Washer switches to manual dosing mode

Causes

  • Thick or gel-based detergents clogging the pump
  • Dried detergent residue in the i-DOS lines
  • Faulty i-DOS pump motor
  • Air trapped in the dosing system
🔧

Step-by-Step Fixes

  • Run the i-DOS cleaning cycle if available.
  • Flush the detergent compartment with warm water.
  • Use only Bosch-approved liquid detergents.
  • Remove and clean the i-DOS lines if accessible.
⚠️

Safety Notes

  • Avoid using powdered or gel detergents in i-DOS systems.
