Indesit Washer Error Code F10

The F10 error code on an Indesit washer indicates that the pressure switch is failing to sense the water level inside the drum. The pressure switch, also called a level sensor, is responsible for communicating to the control module how much water has entered the machine at any given point in the wash cycle. When the module sends a fill command and receives no feedback signal confirming that water has reached the correct level, or when the signal is absent or outside expected parameters, F10 is triggered to halt the cycle and flag the fault.

The most common root cause is a loss of continuity or a disconnected wiring harness between the pressure switch and the control module. Vibration over time can loosen connectors, and corroded terminals can interrupt the signal entirely. The pressure switch itself relies on a small plastic hose that connects it to the drum tub. If this hose becomes kinked, blocked with debris, or splits, the switch will not receive the air pressure changes it needs to detect water level accurately, even if the switch component itself is functioning correctly.

A failed pressure switch is also a frequent cause. The internal diaphragm or contacts inside the switch can wear out or become stuck, preventing it from registering any water level state. In some cases, the control module itself may be at fault if it is not processing the incoming signal correctly, though module failure is statistically less common than switch or hose issues. Diagnosis should begin with a visual inspection of all harness connections between the switch and module, followed by checking the condition of the pressure hose.
