Jura JURA-ENA-9-ONE-TOUCH user manual

The frequency of changing the water filter on a Jura machine may vary based on usage and water quality. Generally, it is recommended to replace the water filter every 2-3 months or after making approximately 50 liters (13 gallons) of coffee, whichever comes first. However, some Jura machines may have a built-in monitoring system that indicates when the filter needs to be replaced. It is advisable to consult the specific model's user manual or contact Jura customer support for precise information regarding your machine.

There could be several reasons why your Jura coffee is weak. Here are a few possibilities to consider:
1. Insufficient coffee dosage: Check if you have set the appropriate coffee strength level. Adjusting the dosage to a higher setting can make your coffee stronger.
2. Grind size: The grind size affects the extraction process. If the grind is too coarse, water will pass through too quickly, resulting in weak coffee. Try using a finer grind to slow down the extraction process.
3. Coffee bean quality: The quality and freshness of the coffee beans can impact the strength of your coffee. Using freshly roasted, high-quality beans can lead to a stronger and more flavorful brew.
4. Water temperature: The water temperature should be within the optimal range (between 195°F to 205°F or 90°C to 96°C). If the water is not hot enough, it may not extract sufficient flavor from the coffee grounds.
5. Coffee machine maintenance: Regular cleaning and descaling of your Jura machine will ensure it operates optimally. Build-up of mineral deposits or coffee residue can affect the taste and strength of your coffee.
6. Brewing time: Ensure that the brewing process is not too short. If the coffee is being rushed through the system, it may not have enough time to extract the flavors fully.
If you have checked these factors and are still experiencing weak coffee, it could be helpful to reach out to Jura customer support for further assistance.
