Soak the aluminium mesh filters flat in hot water with a non-caustic degreaser rather than a dishwasher, and check whether there is a charcoal filter behind them, which is replaced rather than washed if the hood recirculates.
A Venini hood is the third appliance in a Good Guys kitchen package, and it is the one doing the most to determine the condition of the other two.
It sets the schedule for everything else
A rangehood that is extracting properly removes cooking vapour from the room. One that is not returns it, and that vapour settles on every surface in the kitchen, most heavily on the cooktop directly beneath it and the front of the oven below that.
So the hood is not merely another appliance to maintain. It is the variable that decides how quickly the Venini cooktop and Venini oven get dirty in the first place.
That reframes the effort. An hour spent on the hood twice a year does more for the state of the kitchen than the same hour spent on the oven, because it reduces the rate at which everything else deteriorates rather than resetting one appliance.
Check for a charcoal filter
If the hood recirculates rather than ducting outside, there is a charcoal filter behind the metal grease filters. It handles odour, it is replaced every six to twelve months, and it is never washed.
An original one means the hood has been doing nothing about smell for as long as you have had it.
The filters
Aluminium mesh on most models, soaked flat rather than put through a dishwasher, which oxidises aluminium permanently. Our rangehood cleaning guide covers the method and the impeller housing behind them.
Twice a year is the honest number
Filters want soaking every couple of months, and the impeller housing behind them wants opening far less often than that.
For most households a realistic rhythm is a filter soak on a season change, which is easy to remember and roughly right, plus a proper clean including the housing once a year. That is enough to keep a package hood extracting close to what it did when it was new, which is the entire point.
The alternative pattern, which is the common one, is no attention at all until something smells, by which point the housing is loaded, the impeller is out of balance, and the filters may be past a soak. That is a considerably larger job and it produces a worse result than routine maintenance would have.
What actually goes wrong
A hood never opened, while the oven below is cleaned repeatedly.
An original charcoal filter.
Grey mesh from a dishwasher cycle.
Should you do it yourself?
Do it yourself for the filters, on a schedule rather than when you notice.
Get someone in for the impeller housing, which is where the smell and the noise come from.
