Check the Water Reservoir and Seal
- Remove the water reservoir and examine the seal for damage or debris.
- Clean the seal and reservoir contact area thoroughly with a damp cloth.
- Reinstall the reservoir, ensuring it clicks into place firmly.
Inspect and Replace Water Filter
If your machine uses a water filter (like the De’Longhi Replacement Water Filter), a clogged or poorly installed filter can cause leaks. Remove the filter, check for blockages, and replace if necessary. Follow the manufacturer’s instructions precisely when installing a new filter to ensure a proper seal.
Perform Descaling and Maintenance
Mineral deposits can cause internal blockages or damage seals, leading to leaks. Use a descaling solution like the De’Longhi EcoDecalk Descaler as recommended. Regular descaling extends your machine’s lifespan and prevents leaks caused by mineral buildup.
Seek Professional Repair if Needed
If leaks persist after these steps, it may indicate a damaged internal component, such as a valve or gasket. Contact authorized service centers or professional technicians for a thorough diagnosis and repair.
