I have this machine in my workshop for the 3rd time. It leaks a very small amount and activates the flood protection after 10+ washes. I fitted a sump mod a couple of years ago and can’t see any sign of water from there, even with my endoscope. The water first seems to appear under the heat pump, but I’ve never seen one leak. Does anyone have any more ideas?
Thanks
On intensive watching over many programmes it has turned out to be the heat pump actually leaking from the pump body! Customer has cut her losses and bought new.
