Learn how to properly clean your JURA XS90 OTC coffee machine using official cleaning tablets, a 20-minute process triggered after 200 brews or 80 warm-ups.

Your JURA XS90 OTC coffee machine has just brewed 200 shots—or gone through 80 power-on warm-ups—and now the screen says "Clean machine." You’re not sure whether to ignore it, or what kind of cleaner to use. Wrong tablets can damage internal pipes and leave behind harmful residue. Here’s exactly how to clean it the right way, step by step.

To clean your JURA XS90 OTC, wait until the screen shows 'Clean machine' or the 'c' light under the wetting button lights up, then start the 20-minute cleaning cycle using only official JURA cleaning tablets. Don’t interrupt the process once it begins.

When Does Your JURA XS90 OTC Need Cleaning?

JURA machines track usage closely. The XS90 OTC will prompt you to clean it automatically after either 200 espresso extractions or 80 power-on warm-up cycles. That screen message—'Clean machine'—or the lit 'c' indicator under the wetting button means it’s time. Ignoring the alert risks clogged brew paths and degraded shot quality over time.

What You Need for Cleaning

You must use official JURA cleaning tablets. The company warns that using non-JURA or incorrect cleaning agents can damage internal components and leave residues inside the water lines and brew chamber. Always purchase these cleaning tablets through an authorised JURA dealer or your original supplier to ensure they meet the machine’s specifications.

Step-by-Step: Cleaning the JURA XS90 OTC

Once the machine signals it’s time for cleaning—either via on-screen prompt or the lit 'c' button—you can begin:

Check the display: Ensure the screen shows 'COFFEE READY / CLEAN MACHINE' and the wetting button’s 'c' light is illuminated.
Start the cleaning cycle: Press and hold the wetting button until the display shows '20 MIN. / START YES.' Release to begin. If you want to postpone, turn the dial until 'START NO' appears, press the button to exit—but the 'Clean machine' prompt will remain.
Empty the drip tray and grounds container: When 'EMPTY TRAY' appears on screen, remove both the wastewater tray and the coffee puck container. Empty them completely, then reinstall both parts.
Prepare to rinse: Next, the screen shows 'PRESS RINSE.' Ensure the 'c' light under the wetting button is lit. Place a container under the coffee spout to catch liquid.
Begin rinsing: Press the wetting button again. The display will change to 'CLEANS,' and the machine will begin the full cleaning programme, which takes approximately 20 minutes total. Do not interrupt this process.

Important Notes on the Cleaning Process

The full cleaning cycle takes around 20 minutes and must run uninterrupted. Interrupting the cleaning process can result in incomplete removal of old coffee oils, scale, and residues. Ensure the machine remains powered and undisturbed for the duration. Also, always confirm you’ve removed and cleaned both the drip tray and the coffee puck container before starting—these can harbour old grounds and oils that affect cleaning efficacy.

Frequently Asked Questions

How often should I clean my JURA XS90 OTC?

Clean your JURA XS90 OTC after every 200 espresso extractions or 80 power-on warm-ups. The machine will notify you with a 'Clean machine' message or a lit 'c' button under the wetting control when it’s time.

Can I use non-JURA cleaning tablets in my XS90 OTC?

No. Only official JURA cleaning tablets are approved for use. Non-JURA or incorrect cleaners may damage internal components and leave harmful residues in the coffee lines and brewing chamber.

Do I have to finish the full 20-minute cleaning cycle?

Yes. Once started, do not interrupt the cleaning process. Stopping early can leave residues and result in an incomplete clean, which may degrade future coffee flavour and machine performance.

Where can I buy the correct JURA cleaning tablets?

Purchase JURA cleaning tablets exclusively through authorised JURA dealers or your original machine supplier. This ensures you receive the correct formulation designed specifically for your model.

What should I do before starting the cleaning cycle?

Ensure the machine displays 'COFFEE READY / CLEAN MACHINE' or the 'c' light is on. Also, before beginning, remove and empty both the drip tray and coffee puck container—then reinstall them properly.
