Jura E8 Error Codes & Messages? What Each One Means

The E8 Speaks in Messages, Not Codes

A Jura E8 tells you what's wrong in plain words, either on the start screen or in the JURA Cockpit. Its manual defines only two numbered errors. Error 2 and Error 5 mean the machine got too cold and has disabled heating for safety: let it warm to room temperature. Any other "Error" means switch off and call JURA. Every other E8 problem has a message with a fixed answer, listed below.

The E8 manual describes no brewing unit you can take out, no service menu and no counter you reset by hand. The fixes below are all from the machine's own message and troubleshooting tables.

Try This First

• Read the start screen and the Cockpit. Maintenance prompts (Clean, Descale, Filter) sit in the Cockpit, which you reach by paging through the start screen.
• Empty the grounds container with the machine switched on. JURA says that's the only way to reset the grounds counter.
• Check the drip tray is fully in. "Drip tray not fitted" blocks every drink.
• Has it been somewhere cold? Error 2 or Error 5 just needs room temperature.

E8 Messages and What They Mean

Fix 1: Clear the Water, Grounds and Tray Messages (Works About 35% of the Time)

These three stop every drink, and they're the commonest reason an E8 "won't make coffee". The grounds message works by counting, so emptying it while the machine is off doesn't reset the count.

1. Fill water tank: fill the tank with fresh, cold water and push it back in. Change the water daily.
2. Empty grounds / Empty drip tray: with the machine switched on, take out the drip tray and grounds container, empty both, rinse them with warm water and put them back.
3. Drip tray not fitted: push the tray in fully. JURA also says never to pull the tray out while a drink is brewing.

Time: 2 minutes
Cost: Free
Success Rate: About 35%
Difficulty: Easy

The E8's grounds container holds up to 16 portions, and its tank holds 64 oz (1.9 l).

Fix 2: Answer the Cockpit Prompts (Works About 25% of the Time)

The E8 schedules its own maintenance and shows Clean, Descale or Filter in the Cockpit when a job is due.

1. Clean: the cleaning program takes about 20 minutes and uses one JURA cleaning tablet, dropped into the ground-coffee filler funnel when the display asks. It's due after 180 preparations or 80 switch-on rinses.
2. Descale: about 40 minutes, with 3 JURA descaling tablets dissolved in 17 oz (500 ml) of water. Don't interrupt it. Full steps: Jura descaling guide.
3. Filter (red filter symbol): replace the CLEARYL Smart+ cartridge. With a filter fitted, the E8 won't ask for descaling at all.
4. Too hot when you start a program: wait several minutes, or make a coffee or hot water first.

Time: 20-40 minutes
Cost: JURA cleaning or descaling tablets, or a filter
Success Rate: About 25%
Difficulty: Easy

Use JURA's own tablets. The manual warns that other descaling agents, vinegar included, could damage the machine.

Fix 3: Fix Coffee That Only Drips (Works About 20% of the Time)

The E8 manual gives two causes: the coffee is ground too finely and blocks the system, or the water hardness wasn't set correctly, so scale built up without a descale prompt.

1. Set the grinder coarser (the manual's chapter "Adjusting the grinder").
2. Check the water hardness setting (1-30 °dH) against the supplied test strip.
3. Run the descaling program.
4. Dry grounds behind the grounds container is a related row: your beans give a lot of ground coffee. Lower the coffee strength or choose a finer grind.

Time: 5-45 minutes
Cost: Free (descaling tablets if needed)
Success Rate: About 20%
Difficulty: Easy

Fix 4: Restore Milk Foam (Works About 15% of the Time)

Poor foam, or milk spraying from the fine foam frother, means the frother is dirty, according to the manual. Little or no milk with a very quiet pump means its connector is blocked.

1. Run Clean the milk system with JURA milk system cleaner (JURA warns other cleaners can block the frother).
2. Dismantle the fine foam frother and rinse the parts.
3. Little or no water or steam, pump very quiet: remove the frother, unscrew the black connector using the hexagonal hole in the measuring spoon, clean it, and screw it back on by hand. Limescale loosened during descaling can block it too.
4. Rinse the milk system after every milk drink.

Time: 5-15 minutes
Cost: JURA milk system cleaner
Success Rate: About 15%
Difficulty: Easy

The E8's HP3 milk pipe and CX3 milk spout should be replaced about every 3 months.

---

Fix 5: Error 2, Error 5 and Other Errors (Works About 5% of the Time)

Only two numbered errors appear in the E8 manual.

1. Error 2 or Error 5: the machine was exposed to the cold for a long time and heating is disabled for safety. Bring it to room temperature and switch it on again.
2. Any other Error: contact JURA customer support. The manual gives no other meanings, so don't trust a number decoded elsewhere.
3. Grinder very loud: foreign objects in the grinder. That's a customer-support job too.

Time: Until it reaches room temperature
Cost: Free
Success Rate: About 5%
Difficulty: Easy

FAQ

What does Error 8 mean on a Jura E8?

The E8 manual doesn't define it. It defines only Error 2 and Error 5 (too cold). For any other error number, switch the machine off and contact JURA customer support.

Why does my E8 still say Empty grounds after I emptied it?

Empty it with the machine switched on. JURA says that's the only way the grounds counter resets. Emptying it while the machine is off leaves the count unchanged.

Can I take the brewing unit out of a Jura E8?

No. The E8 manual describes no removable brewing unit and says the service covers must stay on. Its cleaning program, with a JURA cleaning tablet, cleans it instead.

How do I make the E8's coffee hotter?

Press and hold a product button for about two seconds and change its temperature under Product settings. JURA also recommends prewarming cups, because a cold porcelain cup cools the drink.

Can I switch off the E8's descale prompt?

Not as a setting. With a CLEARYL Smart+ filter fitted, the E8 doesn't prompt for descaling at all. Change the filter when its symbol turns red.
