Common Causes of DeLonghi Coffee Maker Not Pumping Water

1. Clogged Water Line: Scale buildup or coffee grounds can obstruct the water line, preventing water from flowing.
2. Faulty Water Pump: A malfunctioning water pump is unable to draw water from the reservoir.
3. Air Lock in the System: Air bubbles trapped in the system can create a blockage.
4. Clogged or Dirty Solenoid Valve: This valve controls the flow of water into the group head.
5. Damaged Water Reservoir: A cracked or damaged reservoir may leak water, causing insufficient water supply.
6. Electrical Faults: Loose connections or a faulty power supply can disrupt the operation of the pump.
7. Overfilled Grounds Basket: Excessive coffee grounds can block the water flow path.

Troubleshooting Steps for DeLonghi Coffee Maker Not Pumping Water

1. Check the Water Reservoir

• Ensure the reservoir is filled to the appropriate level.
• Inspect for any cracks or damage.
• Clean the reservoir regularly to prevent scale buildup.

2. Clean the Water Line

• Disconnect the coffee maker and remove the water line.
• Use a descaling solution or vinegar to flush out any blockages.
• Rinse thoroughly and reconnect the line.

3. Inspect the Water Pump

• Listen for the humming sound of the pump when the coffee maker is turned on.
• If no sound is heard, the pump may be faulty and require replacement.
