Hi whilst fitting a new pump on a hoover nextra7 I was testing the power to the 2 wires to check for the positive main lead when the wires touched. I have no power to the machine. All fuses and trip switches ok. is there a trip inside the machine ? or have I blown /damaged the machine

Have you tested to see if power is getting to the machine now?

OK, is that yes you've tested or yes there is power getting into the machine?

How far have you tested for power?
To the control board?

Hi there is power to the machine but all lights not working

OK, thanks for that.

Main control board blown is going to be your problem on this.

Can you post the model number from the label in the door recess please?
Once I have this, I'll advise on the next checks.

The number on the plate is HNWF713-80

OK, you'll need to take the top and rear panels off (after unplugging the machine) and locate the "core board".
This is the "brain" of the machine.

Take it out of it's case and check for obvious damage.
Everything is controlled by this board and it's very likely been damaged when the wires shorted out.

Copy and paste the following into a new browser window.

It takes you to a supplier of the board and shows it's price too.

Given the price of it, I'd suggest checking British Gas for a fixed price repair that includes parts and labour.
It costs £125 and you'll get a warranty on the repair that you won't get with diy repair.

Sorry, not good news I'm afraid.
Check the board, get back to me if you need more help.

Hope this helps
