Coffee quality troubleshooting

Coffee tastes weak, flat or different

Taste changes are not automatically a maintenance fault. Cleaning, scale and water can contribute, but beans, grind and drink settings matter too.

THE PROBLEMThe machine is working, but the cup quality has changed.

Ventori only covers checks that sit within normal user maintenance. If the symptom remains after the correct routine, move to manufacturer or engineer support rather than repeatedly running cleaning products.

First maintenance checks

Rule out the simple causes first.

Work through these in order before repeating a maintenance programme.

Progress0 of 3 checks completed

Avoid making it worse

What not to do.

×

Do not change several grind, dose and temperature settings at once.

×

Do not use extra cleaning product in an attempt to improve flavour.

×

Do not treat old or unsuitable beans as a machine-maintenance problem.

Use the exact machine guide

Now match the problem to your machine.

Similar-looking machines can use different buttons, menus and maintenance sequences.

When maintenance is not the answer

Stop if the problem remains after the correct routine.

Move to manufacturer or qualified service support for persistent error codes, leaks, electrical symptoms, burning smells, damaged parts or mechanisms that remain jammed after the normal shutdown and maintenance sequence.
