May I use my broiler to broil fish in the afternoon and use the same broiler to broil rib steak at night?
Answer:
Yes, this is permitted.
Best wishes.

The Taz (Yoreh De’ah 95:3) explains that the prohibition of eating a mixture of meat and fish applies only to eating actual meat and fish together. The taste of meat alone (ta’am), which is emitted by a pot or plate into fish, does not render it as forbidden food, and vice versa.
This is why we may eat fish with clean meat utensils. Likewise, after eating hot fish with a fork, it is sufficient to wash the fork, before using it for meat. We are not concerned for the beliyos in the fork.
Therefore, it is permitted to use the broiler for meat after fish.
Note that although one should refrain from cooking meat and fish together in the same oven (based on Pesachim 76b), even for this there are lenient opinions. See Issur Ve’heter 39:25, as cited in Rema, Yoreh De’ah 116; Shach, Yoreh De’ah 116:1; Taz, above; Darchei Teshuvah 116:16 (quoting from several authorities); Ha’elef Lecha Shlomo 312. For more stringent opinions, see Peri Chadash (116:4); Peri Toar (116:3); Chochmas Adam (68:1).
