Neff dishwasher S5459x2/21
All is well until right to the end of the wash cycle, fill/drains/heats as it should,when it goes onto dry it does not fill up with water.Circulation pump runs dry.Clock ticks down until 1 minute from about 60 or so and stops there,pump still chonking away. But If I add water by adding a couple of bowl fulls, (when it first starts malfunctioning) it circulates, heats it up and goes to the end of the cycle fine. Had someone out to look, he was clueless. Me thinks pcb? Thanks

I would agree as all the component parts seem to be working during other parts of the cycle. Does it do the same thing in all program's?

Thanks for your help!!
Yes. just the cold rinse programme seems to be ok
About 19 mins long and it gets to the anoying beep!
All the others the same. A bucket of water and off it goes!
