Cordless vacuum shows F2 and will not start; often after cleaning filters

Safety first: Remove the battery before handling filters.

Steps:

• Check filter presence: Open the filter compartment and confirm the correct Hoover filter is installed in the right orientation.
• Ensure filter is dry: If you recently washed the filter, it must be completely dry (24 hours minimum). A damp filter can trigger errors and damage the motor.
• Clean seating area: Remove dust from the filter housing and sensor area so the filter can sit flat and actuate any internal switch or magnet sensor.
• Refit firmly: Press the filter into place until it is fully seated and any cover is latched.

If F2 persists: The filter sensor (mechanical or magnetic) may be faulty. Use a genuine replacement filter; if the error remains, the sensor or main PCB will need professional attention.
