Check and Clean the Water Reservoir and Filters
Often, mineral buildup or a clogged filter causes water to leak or spill. Remove the water reservoir and clean it thoroughly with warm, soapy water. Rinse well to remove any residue.
If your model uses a water filter, like the De’Longhi Replacement Water Filter, ensure it is properly installed and not clogged. Replace it if necessary to prevent leaks and improve machine performance.
Inspect and Replace Worn or Damaged Seals
Seals and gaskets in the brewing unit or water pathways can wear out over time, leading to leaks. Carefully examine these parts for cracks, tears, or signs of deterioration.
If you find damaged seals, consult your user manual for replacement instructions or consider purchasing genuine parts. Replacing seals can often be done with basic tools and is a cost-effective fix.
Descale Your Machine to Remove Mineral Deposits
Mineral buildup from hard water can cause internal blockages and leaks. Use a descaling solution like the De’Longhi EcoDecalk Descaler to clean out deposits.
Follow the instructions on the descaler packaging to run a cleaning cycle. Regular descaling (every 2-3 months) helps prevent leaks caused by mineral accumulation.
Perform a System Test and Final Checks
After cleaning and replacing any faulty parts, fill the water reservoir, and plug in the machine. Turn it on and run a test brew without coffee to check for leaks.
Observe the machine carefully for any signs of water escaping. If the leak persists, revisit previous steps or consider professional repair services.
