The black glass version of the V Series wall and island hood keeps a running count of blower hours. Once the count reaches about 100 hours, it puts FG in the display to ask for the aluminum mesh filters to be cleaned. It is an hour counter, not a grease sensor, so it appears whether the filters look dirty or not. Wolf range hood display · also shown as F6 What to do when FG shows on the range hood ### Kind of code Filter 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 to Range 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. ### Shows up as Reading a Range Hood Error Code or Blinking Light A range hood error code may appear as letters and numbers on a display, a light that blinks in a pattern, a filter reminder that will not clear, or a beep with the fan refusing to start. ### Make Wolf Wolf hoods, liners and downdraft vents are looked at in your home, and the owner's description of the problem guiding where the technician looks first. ### Source Wolf support answer: V Series Hood Displays FG V Series VW wall and VI island cooktop hoods with the black glass control, as described on Wolf's own support answer. ## Before you book, in this order.

Switch the hood off and let the filters cool, then take them down and wash them in the dishwasher or in hot soapy water. If it comes back, it needs a visit. ### My black Wolf hood shows F6. Is that a different code from FG? No. The G in FG is easy to read as a 6 on that display, and Wolf states that V Series hoods have no F6 code. Treat it as the filter reminder and clean the mesh filters. ### How often will FG come back on a Wolf V Series hood? Roughly every 100 hours of blower use, because the control counts run time. A kitchen that fries or cooks with a wok most nights will see it well before a kitchen that mostly simmers. ### I washed the filters but FG stays on my Wolf hood. What now? Washing does not reset the counter; the DELAY key held until FF appears does. If FG returns straight after that, the control is not keeping the reset and the hood needs a technician. --- **[Read on the site: Wolf FG: the black glass V Series hood wants its mesh filters washed](https://rangehooderepair.center/error-codes/wolf-fg/)** **[Book a visit with RangeHoodeRepair.center](https://rangehooderepair.center/schedule/)**
