Before You Start

Before beginning, ensure the machine is cool and unplugged if you must move it. Empty the coffee grounds container and drip tray, and remove any remaining water from the tank. Use only Jura-approved products to avoid damaging the internal components. Schedule cleaning on a regular basis: a quick daily rinse, a weekly clean, and a monthly descaling depending on water hardness.

Time estimates: cleaning cycles take about 20–30 minutes, plus 5–10 minutes for rinses. Descaling typically takes 30–40 minutes including soak time. If the machine shows a descaling alert, perform the descaling process before continuing other maintenance.

Step-By-Step: How To Clean The Jura E8 Coffee Machine

Power on the machine and remove the coffee keg or accessories as needed. Rinse the internal path by running a short hot water cycle with no coffee to ensure cleanliness.
Prepare the cleaning solution: dissolve Jura cleaning tablets in the prescribed amount of water per the kit instructions, and pour the solution into the designated cleaning container or water tank if applicable.
Initiate the cleaning program: select the cleaning or maintenance function from the machine’s menu, and follow the on-screen prompts for the exact steps. The machine will run a cleaning cycle and may pause for soaking intervals.
During the cleaning cycle, the brew group will be accessed automatically. Allow the machine to perform the recommended rinses and do not interrupt the process.
When prompted, remove the brewing components to rinse them under warm water. Use a soft brush to clean any residue from the brew group and milk system parts if applicable.
Reassemble the parts, fill the water tank with fresh water, and run a couple of hot water rinses to purge any cleaning solution remnants from the machine.
For milk-based beverages, purge the milk system with clean water and run the milk cleaning cycle if your model supports it. Refill the milk container with fresh milk or use dairy-free alternatives as preferred.
Run a final empty cycle to ensure all residues are cleared. Inspect the drip tray and coffee container for any leftover debris and wipe down the exterior with a damp cloth.
Check the display for any error messages and perform a short test coffee to confirm normal operation after cleaning.
Document the date of cleaning and descaling in a maintenance log for future reference and to follow the recommended schedule.
Schedule the next maintenance window, aligning with your water hardness and usage, to keep flavor and machine performance consistent.

Troubleshooting

Symptom	Likely Cause	Fix	Prevention
Weak or uneven extraction after cleaning	Brew group not fully cleaned or residue remains	Re-run cleaning cycle, then a full rinse; inspect the brew path	Regular maintenance; use recommended cleaning products
Descaling warning remains after cleaning	Descaling cycle skipped or insufficient descaling	Run a complete descaling cycle with Jura descaler tablets	Adhere to descaling schedule based on water hardness
Milk system smells or clogs	Milk residues in tubes or wand	Run the milk cleaning cycle; disassemble and rinse milk lines	Clean after each use if you frequently run milk beverages
Water tank does not drain completely	Blockage or scale in siphon paths	Inspect and clear any blockages; run a complete rinse	Regular cleaning cycles prevent buildup

Common Mistakes

Using non-Jura cleaners or household chemicals, which can damage seals or electronics.
Skipping rinse cycles after cleaning or descaling, leaving behind residues that affect flavor.
Using stale water in the tank, which can contribute to off-flavors and sensor errors.
Not following the correct order of operations for the cleaning and descaling processes.

Tips For Best Results

Keep a consistent cleaning schedule aligned with your usage and water hardness.
Pre-warm the machine if you plan to run multiple cycles in one session to improve flow and reduce mineral buildup.
Store cleaning tablets in a dry, cool place to maintain their effectiveness.
Label maintenance dates on the machine or in a notebook to track cycles over time.

Call A Professional

Contact a professional if the machine shows persistent error codes after a complete cleaning and descaling cycle, or if there are leaks, unusual sounds, or persistent clogs that you cannot resolve with standard maintenance.

Stop signs include persistent water leaks, alarming error codes, or a failure to heat water after maintenance. If these occur, consult Jura support or a certified technician for service.
