Before You Start
Turn off and unplug the machine during any disassembly or cartridge changes. Empty the used coffee grounds container and the milk system if applicable. Ensure the water tank is clean and filled with fresh, cold water. Always use the Jura official cleaning and descaling products to prevent risk of product residue or machine damage. Plan for about 45–60 minutes for a full cleaning and descaling cycle, allowing extra time if you are performing both steps back-to-back.
Step-By-Step: How To Clean Jura E8
- Open the service menu and navigate to the cleaning cycle, selecting the option for cleaning the coffee circuits.
- Remove the water tank, rinse it thoroughly, and fill with fresh water. Reinsert the tank securely.
- Place the Jura cleaning tablet into the cleaning container or follow the manufacturer’s tablet instructions for your model, then insert the container under the brewing head as instructed by the manual.
- Start the cleaning cycle and let the machine run until the cleaning liquid has passed through the circuit. Do not interrupt the cycle, and ensure the drip tray is in place to catch any liquid.
- Rinse the system: empty the cleaning container, rinse it, and fill the tank with clean water. Run a complete rinse cycle to remove any cleaning residue.
- Initiate a descaling cycle using Jura descaler tablets or the recommended descaler product for the E8. This dissolves mineral buildup from the boiler and flow paths.
- Run the descaling solution through the machine following the on-screen prompts. Refill the water tank as needed and monitor the flow until the cycle completes.
- After descaling, perform several fresh-water rinses: fill the tank with clean water and run the rinse cycle 2–3 times to remove all descaler traces.
- Wipe the exterior with a soft, damp cloth. Dry surfaces and reassemble any removed components.
- Run a final test shot by brewing a small coffee to confirm the machine is functioning and flavors are balanced.
- Record the date of maintenance for future reference and set a reminder for the next cleaning cadence based on usage and water hardness.
Troubleshooting
| Symptom | Likely Cause | Fix | Prevention |
|---|---|---|---|
| Water won’t flow during cleaning | Clogged descaling path | Restart cycle or repeat descaling with fresh solution | Regular descaling schedule |
| Rinse cycle stops early | Extinguished flow sensor or air lock | Refill tank, re-prime system, retry | Keep tank topped up during cycles |
| Persistent aftertaste of cleaning solution | Incomplete rinse | Run extra clean-water rinses | Complete final rinse as recommended |
| Error message during cycle | Water supply issue or sensor fault | Check water line, reseat components, reset machine | Regular maintenance to prevent mineral buildup |
Common Mistakes
- Using non-Jura cleaning products or home remedies not designed for the E8
- Skipping the rinse after descaling, leaving trace residues
- Not drying exterior surfaces, which can attract dust or moisture
- Ignoring water hardness and scaling frequency recommendations
Following the manufacturer’s recommended products and procedures minimizes risk and preserves flavor integrity.
Tips For Best Results
- Set a regular maintenance schedule based on usage, water hardness, and coffee strength preferences.
- Always use fresh cleaning solution and do not reuse partially used descaler or cleaning liquid.
- Keep the water tank and milk system (if present) clean and dry between cycles to prevent microbial growth.
- Consider pairing with a compatible water filter to reduce mineral buildup and prolong cycle life.
- Record maintenance dates and keep a simple log for easier future cycling.
Call A Professional
Seek professional service if the Jura E8 shows persistent error codes, leaks, or electrical issues. Stop using the machine and contact a certified technician if:
- The machine fails to power on after maintenance
- Leakage occurs from internal components during or after cycles
- There are unusual noises, smells, or smoke
Pro service may be necessary for internal component inspection or replacement beyond routine cleaning and descaling.
FAQ
How often should I clean my Jura E8?
Daily use benefits from a quick rinse after each use and a full cleaning cycle every 1–2 weeks, with descaling every 1–3 months depending on water hardness and mineral content.
Can I use any descaler with the Jura E8?
Use only Jura-approved descaler products designed for automatic coffee machines to avoid damage and ensure compatibility.
What if the cleaning cycle is blocked?
Stop the cycle, check the cleaning container and flow paths for obstructions, then retry with fresh cleaning solution.
Is it safe to use the machine right after descaling?
Not immediately. Rinse thoroughly with clean water through multiple cycles to remove all descaler residues before brewing beverages.
Should I run a test brew after cleaning?
Yes. A small test brew confirms the machine operates correctly and flavors are balanced after maintenance.
Buying Guide
When selecting cleaning and descaling supplies for the Jura E8, consider several factors to keep the machine in optimal condition and maintain beverage quality.
Size and compatibility: Ensure the cleaning tablets, liquids, and kits are designed for the Jura E8 model or equivalent Jura automatic coffee machines. Check packaging for model compatibility and batch recommendations.
Descaler concentration and mineral management: Descalers vary in potency and environmental friendliness. Choose a product that effectively removes mineral buildup without harming seals or internal components. Consider products that work well with tap water in areas with high mineral content.
Cleaning efficiency: A comprehensive cleaning kit should include cleaning tablets, cleaning liquid, and a cleaning container compatible with the E8. Some kits also provide replacement filters or wipe-down accessories for convenience.
Noise and cycle duration: Some maintenance cycles can be lengthy. Look for products and procedures that align with your schedule, reducing disruption.
Controls and indicators: Modern Jura machines often display on-screen prompts. Ensure you understand the prompts for cleaning and descaling and follow the sequence exactly to avoid errors.
Placement and storage: Keep cleaning supplies in a cool, dry place. Store tablets and liquids out of reach of children and away from direct sunlight to preserve efficacy.
Ease of use: Kits with step-by-step instructions, pre-measured tablets, and clearly labeled components save time and reduce errors during maintenance.
For best results, maintain a routine aligned with the machine’s recommendations, water hardness, and your coffee preferences. A well-planned cleaning schedule helps preserve the Jura E8’s performance and flavor profile. If in doubt, consult the product manuals or reach out to Jura support for model-specific guidance.
