Frequently Asked Questions - JJB6424HM JENN-AIR
Why is my coffee not hot?
Check that the cup is preheated, that the coffee temperature is set to high (Settings > Coffee Temperature), and that the brew unit has not cooled down. Use the Rinse function before preparation to heat the brew unit.
Why does coffee run too slowly or drip?
The grind is too fine. Turn the grind adjustment wheel one click clockwise (toward number 7) while the grinder is running. The effect will be visible after two coffees.
How do I descale the machine?
Press MENU, select Descaling, add descaling solution and water to the tank, then follow the on-screen instructions. The process takes about 45 minutes. Empty the drip tray beforehand.
How do I adjust the coffee grind?
Turn the grind adjustment wheel (located under the lid) one click counterclockwise (toward 1) for a finer grind (stronger coffee) or clockwise (toward 7) for a coarser grind (milder coffee). Only turn when the grinder is running.
How do I clean the milk container?
Place the milk container in the machine, turn the frothing control to CLEAN, place a cup under the spout, and automatic cleaning starts. Then wash the parts with warm water.
What to do if the message 'EMPTY GROUND CONTAINER' appears?
Open the service door, remove the drip tray, empty and clean the ground coffee container. Replace the tray and container. This message appears every 72 hours or if the container is full.
How do I customize a beverage?
Select the MY profile, choose the beverage, adjust the intensity, then let it run until the desired size and press STOP to save. The new size is memorized.
How do I use pre-ground coffee?
Select the ground coffee icon by pressing the intensity, open the door, add one scoop of ground coffee into the funnel, then choose the beverage. Maximum one scoop.
How do I adjust the water hardness?
Dip the test strip in water, after one minute count the colored squares (1-4). Go to the menu Settings > Water Hardness, then set the corresponding level.
How do I activate energy saving mode?
Go to the menu Settings > Energy Saving, then press to turn ON or OFF. This reduces energy consumption but may delay the first cup.
