Following on this thread have fitted gen miele valve and aquastop hose. The tap light still comes on. First wash was ok now she says its back to square one again.
Have been through it taking sump hose off, water seems to flow away quickly
Any other ideas as cant go back many more times

Had the same problem a few weeks ago. Traced to air lock in water supply. Disconnected hose at supply and flushed for a minute until “spluttering” stopped, reconnected and fine ever since
