Miele dishwasher - F78 fault

[coopersim]

Frustratingly, our Miele dishwasher has just today displayed an F78 fault.

I've followed the instructions and reset several times to no avail.

Miele aren't open until next Friday

Any suggestions for alternatives to try other than a simple reset?

Thanks

Thanks I should have said it’s a 6000 series. I did look at previous threads weren’t relavent.

How old is the machine?
The 6000 are new right?

I think it’s about 3 years now under an extended warranty - miele are closed until Friday and I was hoping it was something simple I can have a go at
