What Error 3 Means
Error 3 points to a problem with the water pump — the machine isn't detecting adequate water pressure or flow to complete brewing.
Common Causes of Error 3
- Water pump blocked by mineral debris
- Loose or kinked water supply hose
- Failed or worn water pump
🔧 One Safe Check You Can Try
Check that the water tank is properly seated and filled, and that the water hose connection (on plumbed-in models) hasn't kinked.
⚠ Why You Shouldn't Go Further Than That
- The pump sits near both the water reservoir and live electronics — a spill during a DIY fix can short the control board.
- Forcing a jammed pump impeller can crack the housing, turning a cleanable clog into a full pump replacement.
- This fault can be confused with a simple empty-tank issue, leading you to skip the real fix and keep running the machine with a failing pump.
- Reassembling the water line connection even slightly loose is a common cause of a slow leak inside the cabinet housing.
- Pump access on built-in models typically requires partial removal from the cabinet, a common way this warranty gets voided.
