Weigh up whether new appliance versus fixed six year old appliance.

Call Asko. If the dishwasher still works prob an easy panel replacement.

Have you tried googling it? My Miele fully integrated dishwasher showed an error code and would not run and due to lockdown, I could not get a repairer. I googled the error in desperation and a very kind soul had put a tutorial video on YouTube showing how to take the dishwasher apart and then how to fix the issue and put it back together. There were also Miele offical YouTube tutorials about checking for blockages and other DIY lockdown repairs. I did need to buy (via Bunnings click and collect) special screwdrivers - they were Torx screwdrivers - I needed both size T20 and a precision set (T5 to T10). Dishwasher has been going strong for about a month now and my new Torx screwdrivers have also fixed the loose fridge handle and taken the Dyson hand stick vacuum apart for a really good clean (again, both hand YouTube videos). Good luck!
