Ariston Washer Error Code F01

F01 on an Ariston washer means the control system has detected a short circuit in the triac, a semiconductor component that controls power delivery to the drive motor. This is an electrical fault within the motor control circuit. The washer will not operate normally until the fault is diagnosed and resolved.

No, you should not continue using the washer while F01 is active. A shorted triac means the motor control circuit is not functioning correctly, which can result in uncontrolled motor behavior or continued electrical stress on other components. Power the washer off until the fault is properly diagnosed and repaired.

Repair costs depend on the root cause. If the issue is limited to the CNG Connector Card terminals and no parts are needed, costs are primarily for a technician's diagnostic time, typically in the range of $75 to $150. If the main control board requires replacement, parts and labor combined can range from $200 to $400 or more. A faulty drive motor can push costs higher still, depending on the motor price and labor involved.

The first step you can perform yourself is checking and reseating the terminals on the CNG Connector Card, which requires no special tools. However, if the triac on the control board has actually failed, or if the drive motor is faulty, those repairs involve high-voltage components and are best handled by a qualified technician. Attempting control board repairs without electronics experience carries a risk of injury or further damage.

A reset may temporarily clear the error code from the display, but it will not repair the underlying fault. If the triac is genuinely shorted or the connector terminals are damaged, the F01 code will return as soon as the washer attempts to run a cycle. A reset is only useful as part of diagnosing whether the fault is intermittent or persistent.
