IGT Coral reef slot machine error code 3100

[tom14]

I have an IGT S+ slot Machine that I had a low battery, replaced the battery and power it back up and got stuck in the 61-1 loop I had to use the clear chip to reset it. I did the reset and powered it back up and looked like all was good, till I drop in the first coin. The machine took the coin no Problem, but the hopper instantly kicked out a coin and I got the 3100 error and it will not clear. I believe that the door optics are working, because when I open and close the door the Machine try's to restart, However all that happens is that the hopper kicks out another coin. If I can't get this fix is there any way to bypass the hopper. Any help is appreciated.
Thanks
Tom

okay...I have a few questions to clear up things then we can try to help you fix your machine the way you want. 

  "The machine took the coin no Problem," Did the [Coin Accepted] lamp come on and numbers change in the [Coins Played] display as coins went in? 

"...when I open and close the door the Machine try's to restart..." When you pull up on the latch, watch the [Coins Played] display.  Whatever number is in there will go out then come back on momentarily after you fully close the door latch ALL the way down. 

If I can't get this fix is there any way to bypass the hopper. Yes...but let's try to get it working right first?  We might have to go into your settings and change some hopper limits - which is a little more complicated.

Also, I know of a very clever way to make your [Change/Service] deck button turn into a free credit button if you want.
You would not ever have to use any coins or bills again....but that wouldn't be a true "slot" machine right? lol

Stayouttadabunker,

To your first question, yes the coin accepted lamp came on the the coins played displayed 1.
To question two, when I open and then close and latch the door the coins played display goes out and then comes back on.

The hopper then kicks out another coin, I am now up to 4 coins paid out with the error 3100.

As for bypassing the hopper you are correct it would be good to get it working the right way, bypassing the hopper is going to be my last-resort

What happens if you take out the hopper and apply power to the machine? 

[tom14]

Jim,
I pulled the hopper out and turned on the machine, the error code 3100 was still there open and close the door and it cleared the 3100 and the machine works. So does that mean that my problem is with the hopper and not the machine?

Thanks

Tom.

The 3100 is a coin out tilt.
Generally speaking more coins have been spit out than its supposed to.
The basic function is that power is applied to the hopper, coins pass by the hopper optic until the proper number is counted.
When power is given to the hopper it runs the hopper motor and extends a solenoid to push the hopper brake out.
When the correct number of coins are paid the power stops, solenoid retracts and the spring attached to the hopper brake pulls it back into position stopping the rotation of the hopper motor.


The most common problem with the hopper (generating the 3100) is the hopper brake.
The brake does not engage (or does not engage fast enough) and an extra coin is spit out due to the momentum of the wheel..


If you pull the hopper and look at the back of the hopper
You will see that there is a small spring that pulls the hopper brake into position.
With the brake engaged you cannot turn the internal wheel, if you pull it back it turns.
You might be missing the spring or find that it has broke.


You can replace it by using about 1/2 - 3/4 of a spring from a Bic Pen.

Jay,

I was thinking about that so when I had the hopper out I looked for the hopper brake and spring, didn't really know what I was looking for, but I found what looked like the brake and the spring it's still attached to it and looks good. could a weak spring cause the same problem?
Thanks
Tom.

You are either running out of coins - Ie your hopper is empty you played one coin (so one is in the bucket) and you won 10, it can't pay out what it doesn't have.
OR you are paying too many - caused by a weak or broken spring..... When you pull the brake back and then release it, it should sharply snap back.

[tom14]

I will check out the spring. However the hopper is kicking out a coin when you drop one in the machine and it kick one out the last time I turned on the machine with the hopper installed without me doing anything.

Check out this video I made about 9 yrs ago...might help you?

If the wrong wheel is installed in your hopper, you may get recurring [3100] error codes, besides having a bad or weak brake spring.

(I made a small mistake when I made that video though...there's no "3400" error code...disregard... )

Anyway, there's really only three basic hopper codes for the S+

[3100] : Extra Coin Paid Out (MPU sees an overcount normally due to bad hopper motor brakes)

[3200] : Coin Jammed (MPU sees hopper motor drawing too much amperage)

[3300] : Empty Hopper (MPU sees that it took too long for a coin to go through hopper optics...timed out.)

However, the video I made may help you determine if you have the correct wheel installed...the nibs cannot be spaced apart too wide as in for large casino tokens.

I checked out the hopper wheel it looks like the nibs are spaced to far apart, However every thing was working great up till the battery had to be replaced.
I put the hopper back in the machine with no coins in it and when I power up the machine and it goes through the start up, the machine then shows that it paid out 1 coin and then the 3100 comes up. ( again this is with no coins in the hopper)

Thanks

Tom.

OK, so now you put the hopper back in the machine, you get a 3100 code,  can you clear the code by lifting up and putting the latch all the way down?

[tom14]

I put the hopper back in and power up the machine and got the 3100 open and close the door and the 3100 goes away for a few seconds then comes back and the winner paid display count goes up by 1.


Thanks

It almost sounds like you have a payout going on and you have no coins in the hopper. Put a handful in and see if it completes the payout.

[knagl]

Put a bunch of coins in the hopper and power on the machine -- does it immediately dump all of the coins out of the hopper into the tray even though it shouldn't be paying out anything?

From the limited descriptions you've given us, it sounds like you might have a runaway hopper (ie. a hopper that is constantly spinning even though it should not be running).  The machine is detecting that it has erroneously paid out a coin(s) and throws the 3100 error.  I'm curious if the hopper motor just keeps running.

[jay]

If the winner paid number is going up then it’s not a runaway hopper.
It needs to finish its cycle or you need to use a clear chip to end it.

[Jim]

Since you cleared the machine already I doubt you have any credits that have to be paId out.  let try this!

pull the hopper back out, turn on the machine and clear the 3100 code. then open the door and get into the machine diagnostics ( press the white test button up near the power on/off switch)  this will put you in the test mode (what SP chip do you have in the machine??) look at the labels on the chips  tell us the two numbers. each time you press the the test switch or turn the jackpot reset key you will advance through the menus, each time the numbers in the winners paid window, credits window, and the coins played window will change, use the S+ diagnostic flip cards (found in the  S+section , second topic) to get to test # 3 where you have a 3 in the coins played window, now (do not turn off power) insert the hopper into the machine, with coins in it ( at least 30 coins)  the spin button should be lit (provided the bulb is good) press it, it should turn on the hopper and the hopper should count out ten coins and display that in the winner paid window. let us know the results.  using the flip cards you can test every feature of the machine and set all the settings accordingly.  check all the settings in test # 7,  check all the current settings in the menu where you get a 5_0 or a 1 in the winners paid window, advance through that menu and it will tell you all the current settings of the machine in regards to the pay out selection etc.

Thanks for the info I will have to wait and try it out this weekend and will get back with everyone with what happens.


Again thanks for all of the help so far.

Sorry it took me so long to get back to this, one of my dog got hurt so had to deal with that first.
As to the chip numbers there are game prom: SP1048, reel prom: IGT SS4239 95% Coral Reef 2CM
I took out the hopper and turned on the machine, cleared the 3100 then with the power still on when into the the diagnostics, went to test #3, then put the hopper back in and with one turn of the jackpot reset key the hopper counted out 10 coins did this a couple of times. However when I closed the door and the machine went through its startup and came up ready to play the the machine showed that it paid out 1 coin then gave the 3100 error, turn off the power and pull out the hopper and power up the machine then open and close the door and it resets.

I checked the settings where the coin played was at 0 the numbers that showed up are 5_1, 6_0, 7_0, 8_1, 9_1, 10_0, 11_0, 13_1, 16_0, 30_37, 34_1, 39_1, and the last one is (winner paid 0110) (Credits display 0000).

With the hopper in, 3100 error displayed. IF you open and close the door the error should clear and play normally.
