Hi
Yes it does mean drain problem, however that is only a guide.
More than likely you have a clogged,dirty or faulty Water Indicator (WI) or at worst a faulty PCB. Im assuming you have checked the waste exit? and its circuitry?

It’s the black grid you can see in the sump – twist fit from underneath.

Looks like the new style “OWI” one – it’s at 3 o’clock in the sump.
