What All 4 LEDs blinking
actually means.

Smeg's push-button hoods count running time and, every 100 hours, blink all four LEDs at once. The message is to clean the metal filters and, on a recirculating hood, to replace the charcoal.

What to do when All 4 LEDs blinking shows on the range hood

Kind of codeFilter reminders

The hood has counted enough hours of fan time to ask for its filters: the mesh or baffle grease filters want a wash, or on a recirculating hood the charcoal filters want replacing. Most hoods count hours rather than measure grease, so the light comes on whether the filters are clean or not, and it stays on until it is reset with the key the manual names. A reminder that returns straight after a reset, or a hood that still pulls weakly with fresh filters, is worth a visit.

Usually leads toRange hood filter and baffle service

Cleaning or replacing what catches grease and odor: mesh and baffle filters, charcoal pads on recirculating hoods, and the grease channel.

What not to do

Four LEDs blinking together is not a sign that all four speeds have failed. A single LED blinking over one speed key is the ten-minute timer, not the filter message.

Back to your everyday

Still showing All 4 LEDs blinking?

Three things make the booking useful: the letters or blink pattern exactly as they showed, the full model number from the label behind the filters, and whether the fan still moves air on every speed. With those, the technician arrives with half the answer already worked out.
