How to Cook a German Goose by Radar - S1-E24
Revealing mistake: When the boys set the trash can on fire in front of Klink's office, there is a problem with the trash. While the rest of the waste paper burns down there is one piece hanging over the top edge that doesn't burn, even being in the midst of the flames on that side.

Revealing mistake: Toward the end of the episode, a guard is watching Helga posing in a one piece bikini for Lebeau. As you look past him, you see only blue screen, no view of the surrounding property. Same when Hogan climbs up, you don't see the tops of buildings; you can tell it's on a soundstage.

Revealing mistake: After Hogan and the boys decide to get rid of Tillman, they "accidentally" set fire to the trash can on the Kommandant's porch. To that end they load up a bunch of trash that's been soaked in gas. Then Hogan tosses a lit match in it. The fire starts at the bottom, but all of gas soaked stuff, and the match, were at the top.
Continuity mistake: When Hogan and the crew first see the silent airplane overhead, it has a twin tail. When shown up close in later scenes it has a single tail.
Plot hole: Hogan's men steal the motor from the silent plane. When Klink and Burkhalter inspect the plane, Burkhalter doesn't notice the engine missing. Later Klink doesn't notice the fact that it has been put back. This is totally impossible for two reasons: Firstly, if a propeller airplane misses its motor, there is no place to mount the propeller. Secondly, when we get to see the whole plane, it becomes obvious that it has an open engine cowling which leaves the motor exposed to be cooled by the airstream. The propeller issue aside, if there is enough light to see the hand in front of your eyes, it is impossible to miss either the presence or the absence of an engine inside that kind of cowling. Add to this the fact that both Klink and Burkhalter are Luftwaffe (Air Force) officers and therefore by trade have some experience with airplanes, the whole thing becomes even more ridiculous.
Revealing mistake: At the end, when the boys are in formation and Klink is walking through the ranks, he walks around Hogan's right side. As he does so, you can see LA's Desilu water tower.
Revealing mistake: When the High Command men are watching the "noiseless engine" plane, the camera cuts to a shot of the four of them in the car. To the right (camera's left) of the man in the right side, back seat, you can see LA's Desilu water tower.
The Safecracker Suite - S1-E27
Continuity mistake: While Klink is talking to Hogan and the Major, the chair next to the door is almost centered under a picture frame. When the Major is arrested the chair is moved to the left. When Klink sits down, the chair is centered again. (00:03:50)
The Safecracker Suite - S1-E27
Continuity mistake: As Günther leaves the room, Klink touches his forehead and begins to sit down (or his knees are buckling, not relevant). After the next cut, he sinks down into a chair in a closeup. That same chair was behind Hogan before the cut.
The Safecracker Suite - S1-E27
Continuity mistake: As Schultz is asking about Alfie, saying "Who captured him, the Kaiser?", Hogan's hands are down. A second later, his chin is in his right hand.

Continuity mistake: After saying "I hate to be a killjoy", Newkirk has his fork up and pointed towards Kinchloe. A second later, it's pointed down.
I Look Better in Basic Black - S1-E28
Factual error: When the SS guard is calling Sergeant Shultz after seeing the burning fuse, he addresses Shultz as "Sergeant", rather than the proper German word for Shultz's rank, "Feldwebel."

Other mistake: When Hogan asked the girls if they wanted to try to escape to England, the one in "basic black" said that anything is better than being booked in a German prison camp for three years. How did she know when the war would be over?
I Look Better in Basic Black - S1-E28
Factual error: The American women the SS brings into camp claim to be entertainers having performed for troops. The series is allegedly set in 1942. Before June 6th, 1944 there were no allied troop concentrations in central Europe, certainly not in Germany, and very certainly none of a size and security rating the USO (or probably rather its predecessor organization, since the USO was founded in 1941 and would not have been fully operational yet) would send a troupe of female entertainers to.
I Look Better in Basic Black - S1-E28
Revealing mistake: When Hogan, Newkirk and Lebeau are dressed as the three women captured by the Gestapo, demand the truck be stopped, the wide shot shows that the truck is already stopped, and shaken to simulate it stopping.
I Look Better in Basic Black - S1-E28
Revealing mistake: A very long fuse is laid down then lit by the boys to distract the guards. While it is burning, watch the fuse in the dirt - it is actually being pulled from offscreen to the right of the shot.
Revealing mistake: During the attack with crossbow, look closely at the arrow in the door. You hear the sound of the arrow hitting the door, then see the (now skewered) hat shaking on the arrow. If viewed closely, you see a black thread pulling on the arrow. Also, the arrow is almost straight before the break, then it is down at an angle when Shultz is called in.
The Flame Grows Higher - S1-E31
Visible crew/equipment: Toward the end of the episode, after the two women are taken out by the Gestapo, Shultz, Hogan, Lebeau, and Newkirk are standing having a drink. The camera goes in for a close-up on Shultz, there is a noticeable shadow of the camera on Shultz's coat, and right arm.
The Flame Grows Higher - S1-E31
Revealing mistake: As Hogan, Le Beau, and Newkirk help Schultz up the slope to the "forest fire", there is lumber stacked across a low spot in the top of the bank and covered with "snow" and grass. Probably meant as a path.
The Flame Grows Higher - S1-E31
Continuity mistake: At the end, as Schultz and Hogan come out of the office, there is a blank wall, like a kind of foyer. Any shots of the front door from the inside show the door opens directly into the outer office of the secretary.
Suggested correction: "Hogan's Heroes" is an American television show produced for an English speaking audience. The whole show is shot in English! Did you expect Schultz and Klink to speak German and LeBeau to speak French?
I have seen MANY instances in the show where German characters are speaking actual German phrases (many quite accurately, by the way) and ranks of fellow German soldiers. When the German characters are addressing English-speaking characters in this American-made show, you do expect them to speak German-accented English, however, when German-speaking characters speak German to each other, one expects them to use the proper address and vernacular Germans would use and not mix in other languages. In this case, the SS guard did not know a lick of English when he was questioning some prisoners who were out their barracks, but addresses Sergeant Schultz as "Sergeant" rather than "Feldwebel." Furthermore, why aren't little things like buckets of water used in the show are labeled, "Water" rather than the German "Wasser"? Why isn't the list of rules tacked onto the barracks say "Forbidden" rather than "Verboten"?

The point is that when German characters are speaking to each other, it is assumed by the audience that they are speaking German and we are hearing an English translation for our convenience. In the world of the show, they are using the German term, but we hear the English equivalent.
