When starting up NOVA, you will notice a blue glow coming from the machine. Aside from making NOVA look like a sci-fi rocketship, the color of NOVA’s LED indicators provides you with important information about NOVA’s current status. In this article, we’ll explain what each LED status means.

NOVA’s indicator LEDs are located along the underside of the Y-axis fenders.

{% hint style="info" %}
Note that although the power button also has an LED, it is not an indicator - it will always stay blue.

#### **Yellow Solid**

Yellow solid indicates that NOVA is executing a factory function. This will typically only happen during as part of a support interaction, and should be allowed to continue until otherwise instructed.

## Smart dispenser LED status indicator codes

#### White scanning or pulsing

White scanning or pulsing indicates that the smart dispenser module is initializing.

#### Blue

Blue indicates that the smart dispenser is homed and idle.

#### Green

Green indicates that the smart dispenser is going through a pressure change.

#### Purple

Purple indicates that the smart dispenser is maintaining pressure.

#### Red

Red indicates that an error has occurred.

Blue blinking indicates a probe trigger - meaning, the smart probe module has detected contact.

#### Green blinking

Green blinking indicates that the smart probe module is tuning (adjusting the sensitivity).

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.voltera.io/docs/nova/learn-nova/novas-hardware/led-light-status-indicators.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
