What the E23 Error Means
The E23 error code indicates a fault with the waste water pump on your Siemens dishwasher. This will typically prevent the appliance from draining correctly at the end of the cycle. This fault can only be resolved by a qualified engineer.
Common Reasons This Error Appears
Faulty waste water pump
The pump responsible for draining water from the dishwasher may have failed and will need to be replaced by a qualified engineer.
Blocked pump
Food debris, broken glass or other foreign objects may have entered the pump and are preventing it from operating correctly.
Blocked drain hose
The drain hose leading from the pump to the household drainage system may be partially or fully blocked.
