Coin just falls straight through to Trey I have changed the coin I’ve cleaned all optics I’ve adjusted the
sensitivity screw the rake does not move when dropping coin any help would be appreciated
-
Code 21 is a coin-in tilt. It doesn't have anything to do with the comparitor, it's telling you there's something wrong with the coin optics. Coins should always fall straight through to the coin tray when the machine has an active error (21 in this case). How did you clean the optics? Did you disassemble it and clean it that way? If so, then probably one of the emitters or receivers has failed and you'll need to replace them.
-
thanks tilt. i just used a can of air . after your post i went ahead and took it all the way apart and cleaned it . no difference still code 21. any ideas where i could pick up a new one?
-
I'd check with Jim (Midwest slots). Hopefully that will get you back up and running again.
-
I just received a new one today and installed it sadly it didn’t change anything still have the code 21. Any help would be appreciated.
-
Well son of a gun. Can you post a pic of the inside of your door including the optics? Maybe we can spot something out of place?
-
Should have called before ordering parts, maybe we could have saved you some money. Go to the s plus section, click on the first post, has all the information about a S plus machine. Find the FAQ section, find the coin optic test, do it and tell us what the results are, has this machine ever worked ? with new optics, wiring could be the problem, the ten pin connector has had problems with connectivity, same issue as with the power connector, the connector becomes compressed inside the connector housing and doesn't apply much pressure to the pin to establish a solid connection., you can hold a light behind the connector, and look inside the connector openings, you will see the good connections are up against the top of the opening, the bad ones are not. remove the connector, clean and re adjust.
Hope this helps
Jim

Here are some more pictures
-
And yes it worked for years I was changing the game chip and a pin/tooth broke off I ordered the same chip and here I am? .
-
I don't see anything out of place in the pics. Try the things Jim suggested. Why were you changing the game chip? Did you find the pin that broke off? Is it laying somewhere in the machine where it could cause problems?
-
It’s been a few years sence I was playing it, I must have been doing aset90, or something I don’t remember..The pin broke while I was straightening up the pin, my other game chip seemed like it paid out more often I had two with win I bought it in 2012. I put the set90, in and after that I had a 61,61-1 and now I’m back to the 21. Not sure how to do the optic test. Thanks again for y’all’s ideas I’m still trying to get it working again.
-
Ok. I think you were changing the reel EPROM (SS Chip) that one changes the payback %, the Game EPROM is the SP Chip and changes the games operating system.
Here's a link to Jim's instructions on how to do the optics test. You may have to press the self test button more than 3x depending on your SP chip. Look for the 10_1 in the display.

Okay I pressed the reset 3 times winner paid read’s 10 1 I unplugged and removed the coin comparator and slide a popsicle stick in next piece under the comparator and nothing changes. I also pressed the little white button under the rust colored plug and nothing. Dose this mean this part is bad. I’ll add a picture
-
Mine doesn't do anything at 10-1 either, but 11-1 and 12-1 change from 1 to 0 when I block the optics. So give that a try. Press the button till you get to 10-1, then turn the jackpot reset key. It should turn to 11-1. Now block the optics path with a popsicle stick, piece of paper or whatever. It should goto 11-0 when you do. Then turn the jackpot reset key one more time and it should show 12-1. Block the path again and it should go 12-1 to 12-0.
When done press the self test button repeatedly until the display goes blank and the reels spin. Now press that little white button below the optics connector. It should register a credit and you can hit the spin reels button to play it.
Let us know what works and doesn't from that.
-
Thanks for the response
Tried it on 10 0,11 1 and 12 1 and pressed the button under plug nothing no rell spin or number change?
-
Follow the wires from your optics to the next connector you come to. The optics wiring will go behind the comparitor mounting bracket, but not too far on the other side you should see another square connector. Reseat that connector (pull them apart and plug them back in) and see if that changes anything.
-
I found two unplugged and plugged no change.?
-
Just a heads up I unplugged the rust colored plug while power on and the numbers changed like they were supposed to with the stick?
-
Hmmm, that's interesting. I wonder if you got a bad set of optics? Seems pretty unlikely, but not impossible. Let's see if Jim sees this and can offer any advice?
-
I got the new comparator from Midohioslotmachines.com. I don’t know if any of y’all have heard of them they seem to be legit.
-
Comparitor or optics?
-
in reply #14, you said you had a 10_0, all three should be 10_1,11_1,12_1, when you block the optic, they will change to a 0. when doing test 11_1, you can block the optic and get it to change to 11-0, and you can push the tiny white button and get it to change, you can only do the button on test 11, it will not work on 10 or 12.
if you have a 10-0, WIGGLE the rust colored plug while you observe the display, see if it changes., when plugged in and you are getting a 10_0, that is probably why you are getting a 21 code.

OK I powered up the machine it reads 21 in winter paid. I press the reset once it read’s nothing in winner paid and 0in credits, Press the reset button a second time and it reads2in winner paid and 0in credits, I press the reset button a third time and it reads 10 1 and no change with the popsicle stick. I’d turn the key one time and it now reads 11 0, No change with the popsicle stick while wiggling the wires or pushing the little white button, I turn the key a second time it now reads 12 0 and no change with the stick while wiggling wires but when I push the little white button it changes to 12 1. I hope this helps. Sorry for the mixup the 10 1 was right but the others didn’t have the one.
Also is there a page that tells you what winner paid and credits numbers should read from fresh power on for every time you push the reset button all the way back to the start, some of mine could be wrong.
-
That document is called a PSR - Program Summary Report.
Its specific to your game chip.
As a contributing member (thankyou) you can go to the Downloads section of the site, then IGT, then PSR and get the document.
It has all the different settings, self tests etc.
I would say your optics are getting power since the white test button is working but it would appear the optics are not working as the optic state is not changing when you block the optic.
This is either the optic board or the wiring harneess.
When optics go bad you typically see one of the three go bad or the whole board is dead. Not that its getting power but no optics responding. Not saying its not possible but if your old optics and new optics are doing the same thing then I think this is a bit of a coincidence and we should be looking at your wiring harness.
-
Okay thank you 🙏 I’ll see what I find out and I’ll get back with y’all thanks again 🙏.
-
Well there is so much information on that page, I don’t know what to do with it. I was looking for a pre-set page with all the correct number’s, so I’m sure if it exist.?
-
I got the new comparator from Midohioslotmachines.com. I don’t know if any of y’all have heard of them they seem to be legit.
Did you change the comparitor or the optics?
-
Yes I changed the comparator.
-
So the optics are the original ones?
-
Yes sir , The machine has always worked perfectly and everything in it was in it when I got it 10 years ago except the game chip and now they’re comparator.
-
I believe your optics are bad, I have replacements available.
here is a complete guide to all the readings in the displays for S plus machines, tells you everything , you can test every feature of this machine using the flip cards.

Did you not read this post?

I thought you'd replaced the optics. I will repeat it again, the coin comparitor has absolutely nothing to do with a code 21 error. It's sole function is to either accept or reject a coin falling through it depending if it matches the signature of the sample coin installed. That's all it does. The credit is added to the machine by the a coin passing through the optics in the proper sequence and time.
Get with Jim, get new optics, and you should be back in business.
-
Okay I’ll give it a try, thanks 🙏 again 🙏
-
Awesome people on here got ahold of Jim he is sending me a set of optics hopefully I’ll be up and running. Thanks for all of y’all’s help, I’ll let y’all know when I get going again.
-
OK I have installed my new optics I have closed the door Reels Spin no codes but the coin just fall straight through no action. 🤷♂️
-
Its good to see the 21 error cleared. This sounds like your optics are working.
If you press the tiny tiny button on the optics do you get a test credit ?
re-doing the popsicle test does your zeros change to 1's or vice versa.
Since you also replaced the coin comparator is there a sample coin in the comparator ?
There is a sensitivity adjustment on the comparator have you adjusted this.
Typically you turn it all the way (low) and then comeback about a 1/4 turn.
-
You can also wiggle the two grey wires on top of the coin comparitor and trying another different sample coin.
-
The popsicle test works the comparator is adjusted all the way to the left
-
I put a different coin in the comparator and attached and reattached all the wires wiggling so on nothing is happening.
Should I use the Utility chips I have a set 90 and an IVC 123 ?
Also I’m using the original comparator. I sent the other one back It seemed like the consensus was there was nothing wrong with my comparator.🤷♂️
-
The 21 cleared. This tells me the optics are getting power and each of the ABC optics are reporting closed.
If the optic is blocked, dirty or no power you get the 21. I don't think wiggling makes a difference unless your trying to clear a 21.
Its cleared it should be good.
The micro button on the optic should put on a test credit that you can play with the door open. Again this is a test of the health of the optics ....
1. Do you get this test credit ??
The popsicle test is to block each of the optics and ensure it goes from a 1 to a 0. There are 3 optics ABC and that is why there are three tests.
2. Is this working.
3. When the door is closed - is the message blinking (or solid) that says insert coins ??
If 1, 2 & 3 is working then you now have either a comparator problem or the solenoid associated with the hopper rake is not working.
What is the comparator number and letter CC-16?? you mentioned you replaced it. Does the one that you replaced it with have the same letter ??
-
Should I use the Utility chips I have a set 90 and an IVC 123 ?
No. The SET chip is for the bill validator (if you have one), and the IVC 123 is a RAM clear chip, which isn't going to help right now.
Is your Insert Coin lamp on when the door is closed?
Have you tried adjusting the sensitivity down on the comparator to make it less likely to reject coins? Here's a tutorial:
Slot machine repair - Coin Comparator adjustment to make it more likely to accept coins (http://www.youtube.com/watch?v=DDZdqBx4CAU#)
-
No I don’t get a test credit,& the popsicle does not do anything on the 10 1, 11 1 switched to 11 0,and 12 1 switched to 12 0.
With door closed the insert coin is blinking, and coins played is blinking.
I tried to get the test credit all three times. And I have not changed my comparator maybe I’ll need to get one again
-
Okay Gentlemen I adjusted the Comparator ended up in the center of left and right I am up and running thank you so much for all your help you guys are the best
-
Thanks for the screen shot.
The machine thinks the door is closed and ready to accept coins.
This tells us the door optics are good, and there are no other errors on the machine that would tell it to ignore coins.
The first thing we need to make clear - is that there is NO relation between the optics and the coin comparator.
They are two different coin checks.
If you are not getting a test credit from pressing the tiny button on the optics board then forget about doing anything with the comparator as the coin optics are bad.
Even with the coin comparator removed you should be getting a test credit by pressing the tiny (tiny) button on the optics.
The popsicle test breaks the invisible beam on each of the three optics. If the numbers are not changing then the optics are bad.
It would appear that 10,1 is bad on the optics. You can try to disassemble and clean with water on a qtip but don't use alcohol as this will damage them.

Glad your S+ is up and running!! :applause:
-
I am up and running thank you so much for all your help you guys are the best
Excellent, glad to hear it. Congratulations!
-
Thanks again to all of y’all and to Jim for the coin optics. :thank_you:
