What the Error Code Means
Error code 4 generally means the brewer detected a temperature or flow condition and paused for safety.
It indicates the machine wants normal conditions restored before it continues.
Common Symptoms You May Notice
- The brew starts but stops before the cup fills.
- The brewer may power down or refuse to start a new cycle.
- The display shows error code 4.
Most Common Causes (From Least to Most Serious)
- Water temperature is outside the expected range: If water is not heating normally, the brewer can pause to protect itself.
- Temporary flow interruption: A brief blockage or low water level can trigger a protective stop.
- Brewer needs routine cleaning: In many cases, light buildup can affect flow or temperature readings.
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.
- Let the brewer cool for a few minutes, then run a water-only brew cycle (no pod).
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 or the brewer stops repeatedly.
- You notice leaks, electrical smells, or unusual heat.
