80 % of returned machines can be avoided!!!
Some components vibrate loose or out of position on the trip home. Please check the following:
Automatic Machines (machines that grind beans inside)
- Check that the brewer unit is locked in correctly. Open the door and push the brewer in firmly.
- Check the dreg draw is securely in place.
- Ensure you have beans in the hopper.
- Check lines are align on brew unit.
Getting ready to go
ALL MACHINES (Automatic – grinds beans and Manual – fill portafilter)
- Fill the machine with water and no water filter BEFORE you turn the machine on.
- If you have a new water filter you need to soak it first for 3 minutes
- Ventilate the machine. Open the hot water tap and run water through until “ventilate” is off the screen OR the loud noise is gone. You should have clear water flow. This process gets water into the boiler and removes the air.
- On manual machine run at least 1 cup of water through steam arm
- Automatic Machines- This process may need to be repeated 2 or 3 Times.
Otherwise you will probably trip a thermal overload on the machine. This will need to come back in.
As the repairer of commercial and domestic machines we sell the products we use. We constantly witness repairs undertaken to repair the damage caused by insufficient cleaning.
- De-scale: Every 3-4 months at most, depending on usage. A de-scaling agent should be run through the machines water circuit to remove lime, calcium and other contaminates that have deposited from the water supply. This may not improve the quality of each coffee but it is necessary to prevent small water jets, steam arms, flow meters and boilers from blocking up.
- Detergent: Every 30 coffees or each time you fill the bean hopper a cleaning tablet should be put through the brewer of the machine. Some machines have a special cycle and even a “door” to insert the tablet. Failure to do this will result in oils building up in the brewer or group handle. Coffees will lack crema and taste bitter as the oils go rancid. In automatic machines, it will also stress the internal components leading to increased failures.
- Anti-bacterial cleaner: Would you drink from a cup that had milk in the bottom of it for a day? Of course not. Failing to clean your milk line is the same. The length to use-by-date, treatment type (eg. non/pasteurised, UHT) and room temperature will all affect for how long milk is safe. Furthermore, small vent holes are used to create froth from milk, these block up due to stale milk build-up.
Draw clean water through the line after each usage period. DAILY (at least) clean the milk line with an antibacterial agent.

This Guide will lead you through the process of unjamming a Global or Quantum Coin changer payout base.
You will recognise a payout jam when either tubes A & B or tubes C & D will not payout when the inventory buttons are pushed. You may also hear the payout motors squealing as they try to work against the jam.
Do not attempt to clear a jammed coin with screwdriver as this will cause further damaged to the payout base and further jams.
To unjam the payout, the payout sweeper and coin must be removed, the driver gears returned to home position and the sweepers replaced.
To achieve this follow this procedure.
- Remove the three payout base screws and remove the lower payout base cover.
- Remove the payout sweepers and any jammed coins. When removing the jammed sweeper pull it out with your finger at the gear teeth, whilst pushing the upper part in toward the tubes, so as to ensure the sweeper arms don’t break when the sweeper is removed
- Whilst the sweepers are removed, power-up the changer so as the driver gears re-align.
- Refit the sweepers ensuring that the timing marks on the sweeper and driver gear line-up, also ensure the wire circle on the top of the sweeper lines up with the sweeper’s hole.
- Refit the lower payout base, ensuring the coin clearing arm is in the proper position to allow the base to the replaced easily.
- Refit the payout screws, gently so as to not damage the plastic housing, do not over tighten the screws, and ensure that all coin tubes are seated correctly.
Do not use any form of lubrication (eg. WD40, grease) for the payout as the will clog the sweepers and cause further jams.
Test the coin payout from all tubes, if jamming continues send coin changer to be serviced.
The first point to understand is that you are not setting prices to each selection. With any mechanical machine, you are setting prices to that grouping of switches, which might be one or more switches.
The second point is that you need to know if you have a single or 4 price machine. Look for a vend relay that clicks when credit reaches the set price. If you have a relay, then you have a single price machine and must set switch B correctly below.
Located behind the acceptor in the middle right hand side of the changer housing are twelve switches. The vend price is set using the first eight switches, the last four switches are used to enable or disable different options.
The vend price can be set in single increments up to 255 times the lowest denomination coin accepted by the changer and routed to a coin tube. In most cases this will be a 10c or 5c.
EXAMPLE: If the lowest denomination coin accepted to a tube for payout is 5c, the highest vend price setting would be 255 (times).05 or $12.75. In this case the value of the
price switches are:
1 = .05 5 = .80
2 = .10 6 = 1.60
3 = .20 7 = 3.20
4 = .40 8 = 6.40
When the top of the rocker switch is pushed in,it is in the ON position. If switches 1, 3, and 4 are ON, the vend price woud be $.65, if the lowest denomination coin accepted to a payout tube is a 5c.
Switch A (switch #9)
Controls the escrow feature of the changer.
ON Escrow inhibited
OFF Escrow enabled
Switch B (switch #10)
Selects the operation mode of the changer.
ON The unit will operate as a Four-Price
OFF The unit will operate as a Single-Price changer
Switch c (switch #11)
Vend signal length
ON Vend signal is held until a selection is made
OFF Vend signal is pulsed (300msec)
Switch B (switch #10)
When to enter “Use Correct Change” condition
ON The changer will use the vend price plus the largest denomination coin accepted (U.S. = $1.00). This is the amount of money reported in the tubes to the logic board to shut the correct change light
off. Example: $.50 vend price plus
$1.00 coin = $1.50
OFF The changer uses the factory settings.
U.S. = $1.00, Canada = $2.00
Set the vend price and option switch as desired, press and release the Mode Button located above the price switch. The main logic board LED and “Use Correct Change” light will begin flashing. Within 30 seconds, press and release any one desired selection switch on the front of the machine. The present setting on the price switch is now set for all selections on that price line. Repeat this procedure for the remaining three price lines. Note: If a price is set to zero, that selection will vend for free.
