What the E79 Error Means
The E79 error code indicates that the pump for the intelligent dosing system on your Siemens washing machine is blocked. This will prevent the system from dispensing detergent correctly but may not stop the cycle from running.
Common Reasons This Error Appears
Blocked dosing pump
Detergent residue or fabric conditioner can build up over time and block the dosing pump, preventing it from operating correctly.
Dried detergent in the system
If the machine has not been used for a period of time, detergent can dry and harden inside the dosing system, causing a blockage.
Incorrect detergent type
Using a detergent that is too thick or not suitable for the intelligent dosing system can cause it to block more quickly.
Faulty dosing pump
In some cases the pump itself may have failed and will need to be replaced by a qualified engineer.
Safe Checks You Can Try
Clean the detergent drawer
Remove the detergent drawer completely and clean it thoroughly under warm running water, paying particular attention to the dosing compartments. Allow it to dry before refitting.
Clean the drawer housing
Use a damp cloth to clean inside the drawer housing in the machine, removing any detergent or conditioner residue.
Run a maintenance wash
Run an empty hot wash cycle with a washing machine cleaner to help clear any residue from inside the dosing system.
Restart the washing machine
Turn the appliance off at the mains and leave it for several minutes before restarting. This can clear a temporary fault.
