Inspect and Tighten Loose Connections
Many leaks originate from loose or improperly seated connections, such as the water tank, internal hoses, or fittings. Carefully tighten any loose screws or fittings, ensuring not to overtighten, which can cause damage. Pay special attention to the water tank seal and the area where the water inlet connects to the machine’s internal components.
Examine the Water Filter and Descaling
If your machine uses a water filter, like the De’Longhi Replacement Water Filter, ensure it’s installed correctly and not clogged. A blocked or improperly fitted filter can cause pressure issues leading to leaks. Additionally, descaling the machine with a product like the De’Longhi EcoDecalk Descaler can remove mineral buildup that might compromise internal seals and cause leaks.
Check for Cracked or Damaged Parts
Inspect the water tank, internal hoses, and seals for cracks or damage. Replace any cracked water tanks or damaged hoses with genuine replacement parts. Damaged seals or gaskets should be replaced to restore a proper seal and prevent water from leaking during operation.
Perform Regular Maintenance
Regular cleaning and descaling extend the lifespan of your machine and prevent leaks caused by mineral deposits and buildup. Follow the manufacturer’s instructions for descaling and cleaning routines, and consider replacing water filters periodically to maintain optimal performance.
