The Hot Blast Auto function only cooks 350g of chips for 15 minutes which barely cooks the chips. If I use Hot Blast manual for 25 minutes they are also only slightly more cooked. P.43 of the manual shows a microwave + Hot Blast function, but there is not a button for this. How can Frozen Oven Chips be cooked using Microwave and Hot Blast, there is no Wattage shown, and so the Combi Button cannot be used either.
P.43 Appears to refer to the Microwave and Hot Blast function, but if you follow the guide on P.31, you cannot use Microwave and Hot Blast without choosing power output that is not shown on P43 for Frozen Oven Chips
I cook 250g of oven chips on H5 high rack, and if its a bigger helping I select the 350g option. They cook perfectly. Not cooked home made chips as I don't buy potatoes.
