Quick answer: The Vertuo Next manual gives two first checks for coffee that is not hot enough: preheat the cup with hot tap water and descale the machine if necessary. Start with the same capsule size, a preheated cup and no cold milk so you can tell whether the brewer or the serving setup is cooling the drink.
What “not hot enough” can mean
A large cold ceramic mug, a small espresso serving and refrigerated milk can make a drink feel cool even when the machine completes a normal brew. Compare like with like: the same capsule, cup and time from extraction to tasting. If the machine dispenses no coffee or only water, this is a different symptom; see Vertuo Next water-flow checks.
A controlled four-step test
- Warm the vessel. Fill the cup with hot drinking water from the tap, empty it and brew immediately. This is Nespresso’s first manual check. Do not use boiling water on a cup that is not heat-safe.
- Remove serving variables. Brew a fresh capsule of the same size without cold milk or ice. Taste promptly. If this fixes it, warm the milk separately for milk drinks and use a cup suited to the serving size.
- Look for other scale clues. If flow has changed or the machine prompts for descaling, follow the exact Vertuo Next descaling sequence, including its rinse. Do not improvise a chemical mix or assume that a cleaning cycle and a descale cycle are the same.
- Retest the same drink. Compare with the baseline after the machine returns to normal brew mode. If it remains distinctly cool under the same conditions, contact Nespresso for a machine assessment.
What not to change
Do not open the case or bypass heating protections. The user manual’s hot-coffee troubleshooting is limited to cup preheating and descaling. A persistently cold output after those checks warrants manufacturer support. If the button has no light at all, use the power diagnosis; if it flashes, identify the light pattern before repeating a brew.
FAQ
Will a cleaning cycle replace descaling?
No. The machine has separate routines. Follow the one the manual calls for when scale is the concern.
Should I compare a coffee-size capsule with an espresso?
No. Compare the same capsule size, cup and serving conditions; volume and cooling time change the experience.
