Ignoring the salt and rinse aid, the wash light flashing indicates a leak into the base of the appliance.
Unplug the appliance.
Empty the dishes out.
Pull the machine out.
Put a towel across the back at the bottom.
Tilt the machine rearward until it's nearly on it's back.
Water will drain out the rear of the appliance.
Once drained, stand the machine up and try it again.
If it starts work and faults again, let me know.
Hope this helps
Let me know how it goes or if you need more help
As I said, the wash light indicates the anti flood device is activated.
You won't always get a lot of water as it only takes a tiny amount to activate the anti flood device.
Let me know what happens.
No problem, just post here again and I'll pick up.
If you use the help button on your screen you can contact customer services.
Explain to them and hopefully they can help you.
I'll also pass it to the moderators to see if they can help.
I'm pleased that you're happy with the service.
Hopefully you won't need to make a lot of use of us.
Good luck with the appliance.
