Jura E6 Error Codes & Problems? Complete Fix Guide

What an E6 Message Is Asking For

Most "errors" on a Jura E6 are requests: fill the tank, empty the grounds, rinse the milk system, clean, descale. The E6 manual defines only two numbered errors: ERROR 2 and ERROR 5, which mean the machine was too cold and heating is disabled until it warms to room temperature. Any other ERROR number is a call to JURA.

One row is unique to the E6, Z6 and Z10 manuals: Fill water tank doesn't appear even though the tank is empty. The cause is limescale in the tank, and the fix is to descale the tank itself. Several E6 guides online miss it.

Try This First

• Look in the Cockpit (the cockpit button on the start screen). That's where Clean, Descale, Filter and the milk-system prompts sit.
• Empty the grounds container with the E6 switched on. It's the only way to reset the grounds counter.
• Check the drip tray is pushed fully in.
• Think about where it's been. A long spell in the cold explains ERROR 2 and ERROR 5.

Fix 1: Empty, Fill and Seat Everything (Works About 35% of the Time)

The tank, grounds container and drip tray each block every drink when they need attention, so they explain most "dead" E6 machines.

1. Fill the 64 oz (1.9 l) tank with fresh, cold water and seat it.
2. With the machine on, empty the grounds container (it holds up to 16 portions) and the drip tray, rinse them and put them back.
3. Push the drip tray in until it's fully seated.
4. Fill the bean container if Fill bean container shows. You can still make hot water and milk without beans.

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

Fix 2: Descale the Tank If "Fill Water Tank" Never Shows (Works About 15% of the Time)

If the tank runs dry and the E6 doesn't ask for water, its manual blames a lot of limescale in the water tank. The answer is to descale the tank, separately from the machine.

1. Remove the tank and take out the CLEARYL Smart filter if fitted.
2. Fill the tank and dissolve 3 JURA descaling tablets in it.
3. Leave it for several hours, overnight for example.
4. Empty and rinse it thoroughly, refit the filter, refill with fresh water.

Time: Overnight (5 minutes hands-on)
Cost: 3 JURA descaling tablets
Success Rate: About 15%
Difficulty: Easy

Fix 3: Run the Prompted Programs (Works About 25% of the Time)

The E6 asks for each job when it's due. Each program is short and guided on screen.

1. Clean: about 20 minutes, one JURA cleaning tablet in the ground-coffee filler funnel when asked. Due after 180 preparations or 80 switch-on rinses.
2. Descale: in the Cockpit, press Descale, then Start. Use 3 JURA descaling tablets dissolved in 17 oz (500 ml) of water, and allow about 40 minutes. Step-by-step descaling.
3. Filter: replace the CLEARYL Smart cartridge when its symbol turns red. With one fitted, the E6 doesn't ask for descaling.
4. Too hot: wait, or make a coffee or hot water, then start the program.

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

Fix 4: Coffee Only Drips, or Grounds Pile Up (Works About 15% of the Time)

The E6 table has three causes for a dripping coffee: grounds too fine, blocking the system; water hardness not set correctly (so it hasn't asked for descaling when it should); or scale.

1. Set the grinder coarser.
2. Check the water hardness setting (1 °dH to 30 °dH) against the supplied test strip.
3. Run the descaling program.
4. Dry grounds behind the grounds container: your beans make an above-average amount of grounds. Lower the coffee strength or choose a finer grind.

Time: 5-45 minutes
Cost: Free
Success Rate: About 15%
Difficulty: Easy

Fix 5: Milk Problems and ERROR Messages (Works About 10% of the Time)

The E6 has the HP1 milk system with an interchangeable CX3 milk spout.

1. Poor foam or milk spraying: clean the fine foam frother with JURA milk system cleaner, then dismantle and rinse it.
2. Little or no water or steam from the frother, pump very quiet: a blocked connector. Remove the frother, unscrew the black connector with the hexagonal hole in the measuring spoon, clean it and screw it back by hand.
3. ERROR 2 or ERROR 5: let the machine reach room temperature.
4. Other ERROR messages, or a very loud grinder: contact JURA customer support.

Time: 5-15 minutes
Cost: JURA milk system cleaner
Success Rate: About 10%
Difficulty: Easy

E6 Settings Worth Knowing

• Switch off after: 15 minutes, 30 minutes, or 1-9 hours after the last action.
• Factory setting resets the E6 to factory settings, and the machine then switches off. It restores settings. It doesn't clear a fault.
• Product settings: hold a product button for about two seconds to change its strength, Volume and Temperature.
• JURA WiFi Connect is optional on the E6 and plugs into the service socket.

When to Call JURA

• Any ERROR other than 2 or 5

• Burning smell or damage: unplug immediately
• Anything behind the covers: "NO user serviceable parts included"

FAQ

Does the Jura E6 have error codes?

Only two, according to its manual: ERROR 2 and ERROR 5, both meaning the machine was too cold and heating is disabled. Everything else is a plain-text message with its own fix, and any other ERROR number means contact JURA.

Why doesn't my E6 say Fill water tank when the tank is empty?

The manual's cause is a lot of limescale in the water tank. Descale the tank with 3 JURA tablets left in it for several hours, then rinse it well.

Is the E6 the same as the E8?

Close, but not the same. The E6 has the HP1 milk system and an optional WiFi Connect. Its table includes the tank-limescale row, and it has separate Rinse and Clean prompts for the milk system. The maintenance programs and tablet amounts match the E8's.

Will a factory reset fix my E6?

Not a fault. The Factory setting item restores the settings and switches the machine off. For ERROR messages other than 2 or 5, the manual says to contact JURA.
