Roku Error Code 006 — What It Means & How to Fix It

What Does This Error Mean?

Roku error 006 means the device does not have enough free storage space to complete an action. This could be installing a new channel, downloading a software update, or adding content. Roku devices have a small amount of built-in storage — usually between 256 MB and 1 GB. That space fills up over time with channel data, cache files, and app updates. Freeing up space by removing unused channels usually fixes this quickly.

Affected Models

Common Causes

Too many channels are installed and their combined storage has filled the device
A large software update cannot install because there is not enough free space
Channel cache files have accumulated over time and are consuming available storage
The device's internal storage has been partially corrupted, reducing usable capacity
An older Roku model with very limited storage is running more apps than it can handle

How to Fix It

Remove channels you do not use. On the Roku home screen, highlight any channel you want to remove, press the star (*) button on your remote, and select 'Remove Channel.'

Each channel takes up storage even when you are not using it. Removing just a few rarely-used channels can free up enough space to fix this error.
Restart your Roku after removing channels. Go to Settings > System > System Restart. This clears temporary cache files and refreshes the available storage count.

Cache files are not immediately freed when you delete a channel. A restart flushes these and reclaims the space.
Check your available storage by going to Settings > System > About. Some Roku models show storage information here.

Not all Roku models display storage stats, but checking can confirm whether removing channels made a difference.
If you still need more space after removing channels, do a factory reset. Go to Settings > System > Advanced System Settings > Factory Reset.

A factory reset completely wipes the device and gives you the maximum available storage. Your account and subscriptions are safe in the cloud — you just need to re-add your channels.
After the factory reset, only reinstall the channels you actively use. This prevents the storage from filling up again quickly and keeps your Roku running smoothly.

You can always add channels back later. There is no limit on how many channels you can have in your Roku account — only a limit on how many can be installed on the device at once.

When to Call a Professional

Roku error 006 does not require professional help. If removing channels and performing a factory reset does not resolve the storage issue, the internal flash storage may have a hardware problem. In that case, the most practical solution is to replace the Roku device — entry-level models start at around $25.

Frequently Asked Questions

How much storage does a Roku device have?

Roku devices have a small amount of built-in flash storage, typically between 256 MB and 1 GB depending on the model. This is much less than a phone or tablet. It is enough for a reasonable number of channels but fills up if you install many apps. Roku does not support expandable storage via SD cards or USB drives for app storage.

Can I use a USB drive to expand Roku storage?

No, Roku does not support using USB drives or memory cards as additional app storage. The USB port on some Roku models is only for playing media files like photos and videos stored on the drive. If you need more channel storage, the only option is to remove channels from the device.

Will I lose my subscriptions if I remove a channel?

No. Your subscriptions are linked to your account, not the device. Removing Netflix, for example, does not cancel your Netflix subscription. When you add the channel back, you simply log in and your subscription is still active. The same is true for any streaming service you subscribe to through Roku.
