FA indicates a problem with the optical water indicator.
Take out the filters and on the right wall of the sump you'll see a black grid.
Clean this out carefully, don't burst the membrane.
Once cleaned, pour a kettle of boiling water into the sump getting as much as possible into the black grid.
Reset the appliance, select the hottest wash and try it again.
Let me know what happens.
Thank you for the payment. It is appreciated.
Good luck with it, let me know how it goes.
I've cleaned the black grid in situ carefully with a toothbrush, is it meant to come out?
I;ve got the machine working again on pre wash but at the moment it doesn't want to accept any other programmes. I'm leaving it to finish the pre wash programme at the moment.
It seems to be working OK now, thanks.
Thanks for letting me know.
I'm glad it's running ok now.
Good luck with the appliance.
Thank you for the prompt payment, it is appreciated.
