We repair a lot of DeLonghi machines in Melbourne, from fully automatic Magnifica, Dinamica and Eletta models to the La Specialista range. Here are the problems we see most, what causes them and how they’re fixed.
1. Water leaking into the drip tray or under the machine
Why it happens: on fully automatic models, the brew unit o-rings wear out and leak inside the machine. Worn seals on the water tank valve or a cracked hose can also leak.
The fix: the brew unit needs a service with new o-rings and fresh grease. If water has spread inside, we check the boiler connections and seals too, so the leak doesn’t damage other parts.
2. Weak, watery coffee
Why it happens: the grind is set too coarse, the burrs are worn, or the brew unit isn’t compressing the coffee properly.
The fix: try a finer grind setting while the grinder is running. If it’s still weak, the grinder and brew unit need servicing.
3. Error lights and flashing symbols
Why it happens: common causes are a dirty brew unit that won’t seat properly, a blocked grinder, a faulty flow meter or scale stopping water from reaching the boiler.
The fix: remove and rinse the brew unit, then switch the machine off and on. If the error stays, it needs a proper diagnosis.
4. Milk frother not frothing
Why it happens: dried milk blocks the LatteCrema carafe or frothing tube, or the steam circuit is scaled up.
The fix: run the clean function and soak the carafe parts after every use. If steam is weak with a clean carafe, the steam circuit needs descaling and the valve checked.
5. Grinder noisy but not grinding
Why it happens: oily or flavoured beans clog the burrs, or a foreign object in the beans jams them.
The fix: stop using it straight away. Running a jammed grinder can strip the gears. We clear it and replace the burrs if they’re damaged.
6. La Specialista low pressure
Why it happens: scale in the thermoblock, a worn group gasket or a tired pump.
The fix: descale, replace the group seals and test the pump pressure.
