CB700 Having Issues

[vendman0729]

I have a CB 700 from 2005 which has the red display.

Strangely enough even if there are drinks inside the slot, the machine display says sold out for that selection.

Does any one know how to make this problem go away?

I know some machines have flaps but I don't think this has the flaps that come out to tell the machine that there's no more drinks..

Does resetting the cradle bed (drink metal holder) help in resolving this issue?

And if so how do I home the cradle back to the original position?

 

My 1st selection is water and I use 2 slots which would normally take turns vending one after the other.

It did that before but now all of a sudden only the 1st slot is vending.

Another words the 2nd slot for the same selection isn't even vending now.

 

Also this machine has 12 selections and 14 slots for drinks with the space to sales option.

The strange thing is the first 12 slots allow me to change the bottle and can option settings. 

I can easily go up and down the selections and change from sdep 1 for bottles to sdep 2 to cans.

However the last 2 options doesn't keep the setting that I want.

It always shows a can setting as if the last 2 drink compartments will only allow you to put cans in there.

Is it made purposely this way by the manufacturer?

I don't know it's weird.

 

Any help is appreciated.

You have different issues happening that may all be related to one thing - the door switch.  The door switch must be actuated when the door is closed (or manually pressed by you) in order to reset your sold out conditions.  When a column jams or sells out and sets the sold out flag, the only way that is reset is when the door switch closes after the door is opened to service the machine.  If the door switch is in the open position then you may have difficulty with your programming as well, though if correcting the door switch doesn't correct the programming problem then you also have a bad logic board. 

 

The switch is on a flimsy metal bracket below column 1.  Make sure that both wires to the switch are connected and not damaged.  If the bracket is tight to the cabinet then bend it a bit so the switch comes out further toward you.  After time the bracket can be bent by the door closing on it and push the switch away from contact with the inner door.  You may also find that your switch is damaged as it can get caught on boxes of soda, etc.  If the switch plunger doesn't move easily or is crooked then you need to replace the switch.

Thanks for the response.

I thought about turning the machine off and on as this might also help.

 

AZ have you ever had a CB700?

What's with the last 2 columns on the very left?

I feel like loading them with bottles is easier than cans and take less time..

Worst comes to worst I can put cans in there but I normally prefer to put bottles (Gatorade) in the very left columns as they take more time to load.

 

Anyone else has any tips?

 

By the way how much is a CB 700 worth like mines from 2005?  For the most part it works fine but just minor issues like these do occur.

How about a 2007 CB 500 with the blue display?

I feel like the CB 500's are more reliable and better.  I think they also look better too.

My CB 500s never gave me any problems.

Gatorade usually works fine in the far left columns.  I've worked on tons of these and the biggest problem with them is that the door is almost as heavy as the cabinet is and so the doors tend to sag with age.  I've had to relevel many doors on CB700s.  They also tend to destroy the T-handle cage nut and bracket if the door isn't carefully closed.  The machine is really the same with the red and blue displays with just the electronics changing.  Due to the sheer size of the CB700 I have always been partial to the CB500 once it came out.  It fits through most doors on a pallet jack so it's about the easiest soda machine to move, unless you're one of my customers who tried to pull the machine up his TRAILER RAMP on a pallet jack causing the machine to slide off the jack and crash to the ground.  Just another reason to pay someone who knows what they are doing to move machines.  The CB700 on the other hand is just a friggin' golpher to move, period.

Did you ever get your CB700 fixed?

[vendman0729]

Most of the problems got fixed just by pressing in the white door switch manually but the double vending cans problem I haven't tried to fix yet.

 

Problem 1

So 1 problem I had was when the machine would indicate there's no drinks in the column even after putting drinks in it.

The door switch did reset some features and afterwards the machine did say there's drinks in the column so now it works fine. 

If the door closes normally like it should then it presses in the white door switch inward anyway.

 

Problem 2

Another problem is the machine not saving the depth setting for the last 2 slots which I wanted for cans.

As far as the last 2 slots, its weird because for the 1st time on the machine the display did read depth 2 meaning cans.

Of course this was after I decided to just put in Gatorade in both of the last slots anyway haha.

I don't know how this problem got resolved though really strange.

 

Problem 3

As far as the space to sales problem, before what was happening was even though there were 2 columns to take turns for 1 major selection, only 1 column was vending.

The white switch going inward also fixed this problem.

As if it activated both columns to vend for the same selection.

 

Problem 4

A selection vended 2 mountain dews so instead of fixing it I just decided to put in 16.9oz bottles of Lipton tea which of course works fine anyway.

It's a temporary solution but I will eventually try to fix the problem since I prefer to vend cans over bottles any time any day.

 

It's really weird how vending machines work sometimes.

I bought this account from a guy who had pretty crappy machines (old USI 3014 and old CB 700) for a pretty descent account ($600/month).

I understand its a warehouse but I just can't work with such old crappy equipment.

Wastes a lot of time and will be upgrading this year eventually.

Still debating if I should get credit card readers on upgraded machines since the bill validators get dust and all.

I clean them up good but I think the credit card readers will help combat this issue.

Any thoughts?

[chris in bc]

Yeah, get a hold of Jerry Barton at USI. Field services engineer. 

 

Copy and paste the above 4 problems to his e mail

jbarton@wittern.com

 

Make sure you have the serial number, make and model!

 

I really hope this helps!

I read over your 4 problems again. Sounds like you have mulitple problems. Get jerry to go over the machines STS ( space to sales) for every column, pricing, Can/bottle settings, and anything else

If you are having multiple problems then just replace the logic board.  You need to remember that the door switch will override all sold out conditions the first time it's pressed if the switch is working properly.  After that the machine will try to vend any column tied to a particular selection until it fails to detect a product drop which will then trigger a sold out condition for that selection.  If your drop sensor isn't calibrated correctly or the delivery chute isn't installed correctly which can cause false sensor readings then you can get either multiple product drops or dry vends.  If you need a new board for it you can email me at rbepic4gatgmaildotcom.

Hi, I have a Wittern 3502, pretty much the same machine that is double vending cans on the back far right. The front row vends fine, but the back doesn't really hit the chute very hard. It kind of rolls out.

[AZVendor]

Check that your delivery chute is freely sitting on the brackets in the right and left corners.  If it is then you need to adjust your drop sensor back to the factory setting of DRP1.  If it's already there then you can try changing it to DRP2 and see if that fixes the vends from corner columns.  If it does then check you middle and front columns as well if they all vend they your good to go.  If any other column now won't vend or double vends you probably need a new drop sensor.

[Snack Man 2000]

Selection 13 which is 2nd over back was vending 4 cans. Changed drop sensor setting to 8 and it is down to 2 cans per vend. I guess the sensor is bad.

[AZVendor]

The factory setting is 1.  Try that.

[Snack Man 2000]

On 1setting I get 4 cans on the second back row.

[AngryChris]

You may just need to adjust it

[Snack Man 2000]

Is it adjustable on the board like the cb700? I thought the 3502 was only adjustable by settings menu on the board.

[AZVendor]

Your model has the adjustment in the programming.  Earlier models were adjustable with a POT on the logic board.

[Snack Man 2000]

Called Wittern today, it turns out the chute needed adjusting. The right side has a tab above the door switch. The chute should 1/4 inch from the tab. It was well over an inch. After adjusting chute and setting drop sensor back to 1, everything works as it should.
