The short answer

The smartcard and the decoder don’t match, which published guides call a “smartcard marriage conflict.” Work through the steps below, and confirm current details with DStv, because decoder models and software differ.

What error E17 means

The smartcard and the decoder don’t match, which published guides call a “smartcard marriage conflict.”

Error codes are DStv’s way of telling you whether the problem is signal, subscription, smartcard or Extra View linking. E17 falls under smartcard. See our full DStv error code list to compare.

Common causes of E17

  • The wrong smartcard is in the decoder.
  • Cards were swapped between decoders, which matters with Extra View.
  • The decoder was changed or reset and needs to be re-paired.

How to fix E17, step by step

  1. Check the smartcard number against your account and the right decoder.
  2. Put each card back in the decoder it came with.
  3. Reset or re-pair the decoder through DStv’s self-service tools.
  4. Restart the decoder and wait a few minutes.
  5. Contact DStv if the mismatch stays.
Watch out
Don’t climb onto the roof to chase an error code. Most codes are not caused by the dish. Check the decoder, smartcard and payment first.

Clearing codes with DStv self-service

DStv’s own self-service tools, which include the MyDStv website and app, can clear many subscription and smartcard codes. The exact steps change, so use DStv’s official website and support channels. Never give your login details, PINs or one-time passwords to anyone who contacts you.

When to call an installer or DStv

Smartcard codes are handled by DStv, but an installer can check the decoder, cabling and power. If your decoder also shows a signal code, read the E48-32 guide.

Frequently asked questions

The smartcard is paired with one decoder. If they don’t match, the decoder won’t decode your channels.

Possibly. Make sure each card is in the decoder it belongs to. See our Extra View decoder guide.

An installer can check the cards and cabling, but pairing is handled through DStv. Our team can guide you.

Often yes. Work through the steps above, and use DStv’s self-service tools. If it keeps returning, contact DStv or an installer.
