A dirty machine can lead to all sorts of issues, those obvious, and others beneath the surface. Ask yourself: ‘When was the last time you cleaned your machine? Ideally, you should be cleaning the machine daily. FAULT: NO WATER DISPENSING FROM GROUP HEAD Solution: Set the grind coarser and the motor will begin to operate. Everyone wants to achieve that ‘perfect’ espresso extraction, but if you can’t even dose the volume of grounds you need, then there’s little hope of getting that liquid gold in the cup. This is an indication that the barista has set the grind setting so fine that the blades are touching and the grinder will not operate. FAULT: GRINDER IS ON BUT WILL NOT GRIND COFFEE It is good practice to pour a solution of dissolved espresso cleaner into the drip tray for an efficient and quick fix. If the drain hose is blocked, unblock it either using hot water or a degreaser solution. To alleviate the problem, ensure the drain hose is not jammed or kinked.
This is an indication that the drain hose has been blocked, usually due to excessive amounts of milk, coffee grinds or chocolate being poured down the drip tray. Solution: Most times, when the question is asked: “Is the water leaking clean or dirty?” the response is dirty. FAULT: COFFEE MACHINE LEAKING FROM UNDERNEATH By utilising fresh coffee, the shots will be more consistent and your grinder will require less adjustments. If you are using stale coffee to set the grind, then once fresh coffee is added the barista will witness irregular shots, either too fine or too coarse. Ensure you use fresh coffee to set the grinder. Solution: Adjust your grinder to make the coffee finer or increase your dose.
FAULT: COFFEE DISPENSES TOO QUICKLYĬause: Grind setting is too coarse or not enough coffee has been dosed into the handle. However, if you press a volumetric key and the water shows signs of irregular running or just a drizzle, then this is one instance a technician would be happy to assist with what’s seemingly a bigger problem at hand. Adjust your grind coarser and refine your dose into your basket. If the water runs OK, then the coffee grind has been set too fine or the barista has overpacked the handle with too much coffee. Solution: Take the handle out of the group head and press a volumetric key. FAULT: MACHINE NOT DISPENSING COFFEE OR DISPENSING VERY SLOWLYĬause: Grind setting is too fine or the barista has overdosed the coffee Solution: Ensure the switch is in the correct position. A barista wiping underneath the drip tray may accidentally click the switch under the machine.A barista cleaning the steam arm can accidently flick the switch on the back panel of machine.The switch can easily be altered depending on the location, for example: Many times, customers are unaware of the on/off switch and its different functions. The second switch (or position 2) will activate the heating circuit in your machine and allow your machine to heat and function normally. This function is used mostly by technicians when diagnosing problems and servicing your machine. The first switch (or position 1) will turn on all functions in your coffee machine, excluding your heating circuit. For example, on a CMA Machine (Wega or Astoria) you will have positions 0, 1 and 2, whereas on a La Cimbali or Rancilio machine, you may have two different switches. This may be indicated with two different switches or one switch with different positions. Ask yourself, have you tried turning your machine on and off Most machines have power switches that can be set in more than one position. This is a classic example of how something so simple can be so detrimental. FAULT: MACHINE NOT HEATING AND NO STEAMĬause: On/off switch is in the wrong position.
