Ariston Washer Error Code F10

F10 indicates the pressure sensor is sending a signal the control board cannot interpret as a valid water level state. The board is receiving feedback that reads as both empty and full simultaneously, or as neither. This prevents the washer from continuing its cycle safely. The fault typically points to the CN1 connector card, the pressure sensor, or the hose connecting them.

No, you should not continue running the washer with an active F10 error. Because the machine cannot determine the actual water level in the drum, it risks either overfilling or running a cycle without adequate water, both of which can cause damage to the appliance or your home. Stop using the washer until the fault is diagnosed and corrected.

A reset may temporarily clear the F10 code, but the error will return if the underlying cause has not been fixed. The pressure sensor or wiring fault that triggered the code will continue producing the same contradictory signals once the machine attempts to run again. A reset is useful for confirming the error is persistent, but it is not a repair solution on its own.

Some causes of F10 are DIY-friendly. Checking and reseating the CN1 connector card terminals requires no special tools and is a good first step. Inspecting the pressure hose for kinks or disconnection is also straightforward. However, testing the pressure sensor's electrical output and diagnosing control board faults typically requires a multimeter and some technical comfort, so a technician may be advisable if basic checks do not resolve the error.

Repair costs vary depending on the root cause. Cleaning or reseating connectors typically costs nothing beyond your time. A replacement pressure sensor generally ranges from $20 to $60 for the part, plus labor if a technician is involved. A new pressure hose is usually inexpensive, in the $10 to $30 range. Control board replacement is the most costly repair, often ranging from $150 to $350 or more depending on the model and labor rates in your area.
