Tried that once with some battered fish fillets, same story. They came out kind of sad and soggy. I found that with frozen stuff especially, those few minutes of preheating actually save time in the long run. The machine just seems to work better when it starts hot. Now I just set a timer and go unload the dishwasher while it warms up.

Found paint-able raceways a lifesaver in my last rental upgrade.

Wait, there are actually untouched places left? How untouched are we talking here? Maybe some secrets are better kept quiet.
