Hotpoint Aquarius FDW20 Dishwasher Wash & Dry Lights Flash?

Hi, just had the same problem with ours, “wash & drying” lights flashing. After reading these & other web pages, I feared the worse, spending a small fortune!.
This is what I done.
Unplugged from the mains, this apparently resets the settings (so I was told by an engineer), as the “reset” button was having no effect.
Removed & thoroughly cleaned the filter, even though it appeared to be fairly clean.
Purchased a “quality” dishwasher cleaner, one of those you place upside down in the cutlery basket.
Plugged it in again, presto, no lights flashing.
Set the “wash cycle” to the hottest setting, “A”. made sure the cleaner was in place, then pushed the start button.
We now have a fully functioning dishwasher again. Hope this helps, as it did for us.
Good luck.
