Keurig Coffee Maker Error Code 1 - What It Means & What to Do

Seeing error code 1 on a Keurig coffee maker is frustrating, especially when you just want a quick cup. This code often appears when the brewer is trying to start and is a common alert rather than a sign of immediate danger.

What the Error Code Means

Error code 1 generally means the brewer detected a water supply or flow condition and paused to protect itself.

It points to a condition the machine wants you to address before it can continue safely.

Common Symptoms You May Notice

  • The brewer will not start a brew cycle.
  • You hear the pump briefly, but little or no water dispenses.
  • The display shows error code 1.

Most Common Causes (From Least to Most Serious)

  1. Water reservoir is not seated: If the reservoir is low or not fully seated, the brewer may pause to prevent running dry.
  2. Air or temporary blockage in the water path: A brief interruption in water flow can trigger a protective stop.
  3. Brew path needs routine cleaning: In many cases, light buildup or residue can reduce flow and trigger the alert.

Safe Things You Can Check Yourself

  • Turn the brewer off, wait 30 seconds, and turn it back on to see if the code clears.
  • Remove and re-seat the water reservoir, then refill it to the recommended level.
  • Run a water-only brew cycle (no pod) to confirm water flows normally.

If at any point this feels unsafe or unclear, stop and contact a professional.

When to Stop and Call for Service

  • The error returns after a reset and basic water checks.
  • No water dispenses at all or the machine shuts off repeatedly.
  • You notice leaks, electrical smells, or unusual heat.

Typical Repair Cost Range

$80-$200 is typical for professional service or replacement guidance on small coffee makers, depending on model and warranty.

Costs vary by region, model, and provider. Request an estimate before approving any repair.
