I will try and help with this problem about Zanussi ZDT21006FA Integrated Dishwasher,

Hi Ian sorry to hear about your problem with your Zanussi ZDT21006FA dishwasher. The only thing I can think of here is if the machine is timing out within the allocated fill time. These machines now have a common issue with pressure switches, and I believe there is an upgrade kit available to fix this problem. Have you replaced it with a brand-new pressure switch, or have you just installed another secondhand one?

Even if you install a new pressure switch, it can take some time to recalibrate. It may take anywhere from 5 to 15 minutes before the machine starts filling properly. During this time, you might notice a repeated process of emptying and filling before the machine recognizes the new pressure switch, recalibrates, and begins operating normally again.

I’d suggest giving it a bit more time, especially if you’ve installed a new pressure switch, to allow the machine to recognize it and return to normal operation. More than likely, this is a pressure switch issue.
