Hello,
I have an older D/N pop machine (model # to follow) that decided to continually vend until all of the product was dispensed. Once the customers product was selected this other row of product would begin to vend until it was empty. Any suggestions? Thanks in advance!!

Sounds like it is more then likely a board issue. The model number and type of board would be needed for any real diagnoses.

Thank you! Model # and board type to follow shortly.

Looking around on this machine I don't see anything that states "model #" It does say series 90 on the back of the door, and also says "9 column V4 generic single price 501E/600E" Is any of this info helpful?
Thanks!!


Ok, finally found the model tag against the wall...lol.

Does it give you any letters after the -9? MPC? SII? SIID?

[firstdue]

Nothing at all after the -9. Thanks!!

If your machine is a single price machine (no control board) it could only be the coin mech, vend relay or switches. Exactly what are the symptoms?

After you insert coins and make a selection does it just keep vending the entire machine until it jams? Is it just one column? do you have to keep pressing buttons for each free vend?

[firstdue]

After you insert your coins and make a selection, you will get whatever you selected and then several seconds later this one particular column begins to vend and continues to vend until the column is empty (the only button pressed is the original selection). I don't have any issues with any other columns, or the coin or bill mech. Thanks for the assistance!

What I would first try is spraying the brake on the motors to be sure they are not gummed up and are stopping at the right spot. Unplug your machine, remove the motor cover and spray the motor, brake and switches with WD40 and WD40 only. Lets see if this fixes you up.

Even though WD40 would seem to be the preferd way. I strongly recommend never using WD40 on any vending parts. Wd40 is a penetrant and will premeate the product in the machine and will taste like WD40 from now until enternity. WD40 will thicken under the machines operating temperature and cause more sticking problems.A sticky brake is usually caused by sprayed soda if you will spray the brake, motor,and switches with diluted ammonia it disolve the soda. If you can tell me which sel# is jackpotting I could probably pin point your problem. Also the "E" means its an electronic machine so it may have a triple switch or a double switch (on the motor). For the motor to jackpot the carrier switch has to be stuck or the brake sticking. But for it to take money and vend with a stuck switch is another issue. You may have more than one problem. Just a thought.

WD won't thicken up in the cold. It is barely even a lubricant but it works well to clean switches and flush out gunk. A motor that drifts and drops a switch into the valley of a cam may or may not stop the machine from accepting coins. This is the easiest place to start to try to fix the problem as well as the most common. The nice thing about WD is it will not hurt any plastic used in the machine and it will not short out the switches either which may be a concern with diluting ammonia with water and introducing it to electricity.

Thanks guys for the advice. It is column #8 that is jackpotting...lol. The motor doesn't seem to cycle when it is finally empty. I loaded it a couple times with about 9 cans. 3 rows of 3, just enough to so that it would not show as empty. The jackpotting column is fine until another selection is made, about 10 seconds after the 1st selection is made the "jackpotting column begins. Dropping 2-3 cans at a time about every 10 seconds. I've maintained this machine for several years without any issues at all, the machine is pretty clean inside. I'll see what i can do about cleaning the motor and switches on this column.

I'm not trying to get in a discussion on the solvent or petroleum bases of WD40 and its effect on plastics or prestilites strictly voiceing a highly profitable experience cleaning up effects of WD40. Now to the real issue. If you can give me a little more info. How many switches are mounted on the motors? What is the model number of the coinmech? Is there a schematic on the inner door? If so what is the number in the top left corner? Does it have SII-D? If there is only 1 switch mounted on the motor I doubt if it is a brake problem. Do you know how to price the machine? If so that will help in determining which control system you have. Just a thought.

Ok,
Did a pretty thorough job cleaning. It appears to have switches above and below the motor. It looks very much like this:
http://compare.ebay....4=263602_309572

It has another switch on top (this pic is upside down) that controls the Product empty light on the front of the machine. This light does not change regardless of switch position. The light is always lit.

The coin mechanism is a model MAG30B. The coin mechanism below holding the change says 9300 DEX 3000 series.

There is a retangular box with a red LED to the right of the bill holder and it is usually solid but it begins to flash when it begins it "jackpotting"

No SII-D on the diagram on the inner door.

THANKS!!

We really need to know exactly what type of Dixie this is. If it is electronic or not. The 9300 series is just the designation of the unit and the actual model number will be on the side (9302. 9360...). This would definitely help. Also, does this machine have a digital display to show the amount of coin inserted?

According to the info you've supplied (501E/600E and the link to e-bay showing a motor with 1 switch) you have an electronic control board machine. Therefore the brake would probably not cause the jackpotting. With the problem you are discribing (It doesn't jackpot until another selection is made and runs until it is empty)I'm going to say your control board is bad. If you don't want to replace it right now you can take that selection out of order by disconnecting the wire(s) off the motor. If we can determine which board and system you have there is a possibility it might be an issue we can resolve. Just a thought.

When i was out cleaning it and checking #'s it started "jackpotting" on its own, without making a selection. It ran through several cycles and then quit, even with the column empty. Where would/could i find info on the control board?

Well that adds another twist to the mystery. Now I'm not ready to condem the control board. If the machine thinks there is a jammed can or sold out it will try to rehome the motor every time the machine is opened or closed (activating the service switch). Which points to the switch on the motor but why would it run after making another selection first when they should be isolated. We need to figure out the control is there a control box mounted inside the door top left corner above the coinmech or about half way up the machine to the right of coinmech
by the light bulbs. Is there a schmatic on the door if so are there any #'s in the top left or bottom right. Are there programing directions mounted on the inner door? IF there are programming directions does it tell you to make entries using button on control board or by pushing selection buttons 1,2,3,? Also to start narrowing the issue try swapping wires on sel#8 motor with sel#7 motor and see what happens. Then replace the wires and swap wires on the switches. I've noticed you fail to answer each question we ask which makes it hard to eleminate possible scenarios I know its tough but its really tough for us because we don't have the visual of the machine. So you have to be our eyes and ears. When making a test for us it needs to be one step at a time and tell us what exactly happens. I look forward to resolving your machine issues. We need to know the model number of your coinmech it should be on the left side of the coinmech. We need to know if it has a display on the front of the machine. We need to know what prices each selection is and how you price it. Just a thought

A 9370S is a single price changer and without a digital display, I would guess that it is not electronic. Which would bring us back to the motor again. Did you ever clean up the motors?

Thats not totally so. DN did come out with a control board that did use a single price and or a dummy mech with digital readout. I've only seen 10 or 12 of these machine and consider them a bastard child. They were'nt around long and had issues.I didn't see where he posted it was a 9370s. I saw a "9300 DEX3000" which could mean it was an earlier model 12 pin MDB mech. Just a simple mans thoughts.

I'm gonna bow out of this one and leave it to you vend1ng. Seems no matter what I say you want to contradict me and this is not helping the OP.

However I will say this, a 9370S and no digi would more then likely make it a single price machine. While you are right there were 9370S's used in an electronic machine they are extremely uncommon. Also, just to clarify, MDB is a six pin not 12, 12 pin would be a non intelligent coin mech.

Good luck with the repairs...

I'm sorry you feel I'm being contradictory I did miss the 9307-S post my "bad". I was just trying to voice my opinion as you are. I never intended in attacking your integrity or experience. I was openly trying to discuss possiblities between experienced individuals and to challenge my experience. Your contribution to the board is noted and I bow to your tenure.

Thanks guys for all the advice! I apologize for not answering every question fully and understand it is very tough to diagnose anything with out hands or eyes on the actual machine. Everything including motors has been cleaned...even though they looked pretty clean to begin with.

I started swapping switches and found the double stack switch that sits just under this motor and on one side the switch is what appears to be stuck open. Ordered a new switch and should know shortly if that solves my issues.
