On some Ariston top-load washer-dryer variants: drum position error; F16 displayed and drum may not lock in correct position.

Safety: Unplug the appliance.

Steps:

• Access sensor: On top-load combos, the drum position sensor is usually mounted near the drum pulley or side of the tub.
• Inspect sensor and magnet: Ensure the sensor and any associated magnet or cam are intact and aligned.
• Check wiring: Verify the harness from the sensor to the control board is secure and undamaged.
• Test sensor: Use a multimeter to check for expected resistance or switching behavior as the drum is rotated (refer to service data).
• Replace sensor: If readings are out of spec, replace the drum position sensor.

Note: This code may not apply to all front-load Ariston washer-dryer combos.
