No drain detected in the time allowed. If iot doesn’t drain, find the blockage. If it does drain, thoroughly clean the level switch – black grid in the sump moulding.
Cleaning in situ with an old toothbrush and very hot water will often do the trick. If it has to come out, it’s a twist fit from underneath – third of a turn and pull.
