If the appliance number starts with a V then the model is a Smeg machine , as Martin suggested –
E06 , in my experience , has normally been caused by a blockage at the drum end of the pressure switch hose……and it can be very difficult to get to. I have succeeded clearing this prob in the past by forcing hot water down the pressure hose from the top.
The machine may need some decent service washes/descaling after to help re-occurence of the fault .
