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:
- Washing machine abruptly stops mid-cycle with E12 displayed
- Wash seems to pause and may resume after foam dissipates
- May be associated with interrupted drainage
Possible Causes
- Excessive foam/suds triggering a suds sensor (low)
- Drainage blockage or related drainage issue potentially exacerbated by suds (low)
