Do I Need To Reset

Folks,

Hi, I'm new to this forum... thanks for any help!

I've just heard about a fault with my sister's Indesit washing machine. I haven't yet seen it, and don't even know the model number...

However a quick bit of research seems to indicate that it's probably a pump fault.. (F - 05), and water remains in the machine.

Now I realise that it could be something else, but I have a simple question...

If manage to fix it, either by unblocking pipework, or, if necessary, replacing the pump, do I need to somehow "Reset" so the error code is no longer displayed? If so, how?

Many thanks in advance,

Regards,
