ASKO Washer Error Code S

The S code on an Asko washer stands for a safety step fault, indicating the machine has detected a serious problem and halted operation. The fault is associated with either the motor circuit, including the tacho generator, triac, or safety relay KL1, or a pressure sensor failure where the water level is not reached within 5 minutes. A service technician should inspect these components before the machine is used again.

No, the S code is designed as a safety stop. The washer should not be operated while this code is active. The fault may involve motor drive components or relay failures that could cause further damage or create a hazard if the machine is forced to run.

Repair costs depend on which component has failed. Replacing a pressure sensor or clearing a blocked sensor hose tends to be less expensive, generally in the range of $75 to $200 including labor. Motor components such as a triac or tacho generator replacement can cost more, typically ranging from $150 to $400 or higher depending on parts availability and labor rates in your area.

Some aspects of diagnosis, such as checking for a kinked or blocked pressure sensor hose, can be performed without special tools. However, testing components like the tacho generator, triac, and safety relay KL1 requires electrical measurement skills and access to internal components. For most homeowners, a qualified technician is the appropriate choice for this fault.

A simple power reset is unlikely to permanently clear the S code because it indicates an underlying hardware fault in the motor circuit or pressure sensor system. The code will typically return as soon as the washer attempts to run through the affected cycle phase. The root cause must be identified and repaired for the code to clear and stay clear.
