4. Maintenance and Replacement
To ensure continuous protection and optimal coffee quality, the WMF Water Filter 100 requires regular replacement.
Replacement Schedule:
- Replace the filter after approximately 100 liters of water have been filtered.
- Alternatively, replace the filter every three months, even if 100 liters have not been reached. This ensures hygienic operation and effective filtration.
Replacement Procedure:
- Power Off: Turn off and unplug your coffee machine for safety.
- Remove Old Filter: Remove the water tank and carefully extract the used water filter. Dispose of the old filter responsibly.
- Install New Filter: Follow the installation steps outlined in Section 2 for the new filter.
- Reset Filter Indicator: If your machine has a filter replacement indicator, reset it according to your coffee machine's manual.
- Flush System: Perform a system flush as recommended by your coffee machine's manufacturer to prime the new filter.
5. Troubleshooting
If you encounter issues after installing or during the use of your WMF Water Filter 100, consider the following:
- Reduced Water Flow: Ensure the filter is correctly seated and not obstructed. If the filter is old, it may be saturated and require replacement.
- Unusual Taste in Coffee: A new filter might require an initial flush. If the taste persists or the filter is old, replace it. Ensure the water tank is clean.
- Filter Not Fitting: Double-check that you have the correct WMF Water Filter 100 model for your specific WMF coffee machine (WMF 1000pro, WMF 1000, WMF 800).
- Limescale Still Present: Ensure the filter is installed correctly and replaced according to the recommended schedule. In areas with extremely hard water, descaling may still be necessary periodically, even with a filter.
For persistent issues, refer to your WMF coffee machine's instruction manual or contact WMF customer support.
