What Does Error E12 Mean?
The E12 error on your Simpson Washing Machine indicates an issue with excessive suds or a drainage blockage. This may cause the machine to stop mid-cycle or pause until the foam dissipates. To resolve this, reduce the amount of detergent used to the manufacturer's recommended levels and run a rinse and spin cycle without detergent. Additionally, inspect and clean the drainage components to ensure proper flow and prevent obstructions.
Common Symptoms:

- May be associated with interrupted drainage
Possible Causes
