krups coffee machine not pumping water
If your Krups coffee machine isn't frothing milk properly, produces weak foam or only dispenses steam, our troubleshooting guide explains the most common causes, including blocked milk circuits, steam nozzle maintenance and milk preparation tips recommended by Krups.
Why Is My Krups Coffee Machine Not Pumping Water?
If your Krups coffee machine is not pumping water, only delivers a few drops or has stopped producing coffee altogether, the problem is often related to the water supply, limescale or an interrupted maintenance programme rather than a pump failure. The manufacturer recommends checking the water circuit and completing any outstanding maintenance before assuming there is a mechanical fault.
Check the Water Tank
Remove the water tank, refill it with fresh cold water and ensure it is fully seated when refitted. A poorly positioned tank can prevent the machine from drawing water correctly and may trigger water-related warning messages.
Check for the CALC Indicator
Limescale inside the hydraulic circuit is one of the most common causes of restricted water flow. If the CALC indicator is illuminated, complete the full descaling programme without interruption. On compatible models fitted with a Claris Aqua Filter, remove the filter before descaling and reinstall or replace it once the programme has finished.
Complete Any Outstanding Cleaning Programmes
If the CLEAN indicator is displayed, complete the automatic cleaning programme before attempting further troubleshooting. Coffee oils and deposits inside the brewing circuit can reduce water flow and affect coffee preparation.
Prime the Water Circuit
If the water tank has been allowed to run empty, air can enter the hydraulic circuit. Refill the tank completely and allow the machine to complete any automatic rinse or priming programme before preparing another drink.
Check the Drip Tray and Water Tank Position
The Krups manuals advise leaving the water tank in place until brewing, cleaning or descaling programmes have finished. Removing the tank during a cycle can interrupt water flow and prevent the programme from completing correctly.
Error Messages
Some Krups models display an "Error Code XX" message if the machine detects an internal fault affecting operation. The manufacturer recommends disconnecting the machine from the mains for approximately 20 seconds before restarting it. If the error returns, record the displayed code and refer to your machine-specific support guide.

Frequently Asked Questions
Why is my Krups coffee machine making noise but not pumping water?
This may indicate air in the hydraulic circuit, restricted water flow or that the machine requires descaling.
Can limescale stop my Krups machine pumping water?
Yes. Krups recommends carrying out the descaling programme whenever the CALC indicator is displayed to maintain water flow through the hydraulic circuit.
Should I remove the water tank during a cleaning programme?
No. Krups advises leaving the water tank in place until the programme has completely finished.
Can the CLEAN indicator affect water flow?
Yes. An overdue cleaning programme can allow coffee residue to build up inside the brewing circuit, affecting coffee preparation.
My Krups machine still isn't pumping water. What should I do?
If the water tank, cleaning programme and descaling programme have all been completed, refer to the troubleshooting guide for your exact Krups model for further diagnosis.
