Short answer: check power and isolator, mains water and stopcock, filter head, hopper and grinder, group head blockage, drip tray and waste sensors, boiler fill, error code, and whether anyone changed the grind. Most call outs are one of those nine.
Short answer: before you book an engineer, check power at the isolator, mains water and the stopcock, the water filter head, the hopper and grinder, a blocked group head, drip tray and waste bin sensors, boiler fill, any error code on the display, and whether anyone changed the grind setting. A large share of call outs come back to one of those nine.
Sensor faults are the most common false alarm. Many bean to cup machines will refuse to brew if the waste bin or drip tray is not seated correctly, and the message on screen rarely says so plainly. Remove, reseat and try again.
If the machine runs but the coffee is wrong, it is usually not an engineering fault. Grind, dose and cleanliness cause more bad coffee than broken parts do, and all three are fixable in minutes.
Log what you find. An engineer who arrives knowing the error code, the last service date and the filter change date fixes it faster and charges you for less time.
Most often a sensor or a water supply issue rather than a failure. Check the drip tray, waste bin and stopcock before assuming the worst.
Rarely. It is normally grind, dose or a worn burr set. Grind finer, weigh the dose and check when the burrs were last replaced.
Note the error code first, then power down at the isolator, wait a minute and restart. Some faults clear; if it returns, book the engineer with the code.
Yes. Send us the bag details, roast date and grind setting and we will help you get back to a stable extraction, whether or not you buy from us.
