Weekly backflush

Fit the blind basket

When you stop a shot, the three-way valve releases the pressure from the puck down a tube into the drip tray. Coffee oils travel with it and bake on. Backflushing pushes detergent backwards along that same route. Profitec recommends it every 90 to 140 coffees.

  1. Twist the portafilter left and take it out.
  2. Lever the normal basket out with a spoon handle. A spring clip holds it, so it needs a firm pull.
  3. Press the blind basket in. It has no holes.
  4. Add 3 to 5 g of detergent, about half a level teaspoon.

Run, rinse and brush

  1. Lock the portafilter in, handle straight ahead.
  2. Press the coffee button. The gauge climbs because the water has nowhere to go.
  3. After about 20 seconds, press again to stop. You will hear the valve dump into the drip tray. Repeat until the water landing in the tray runs clear.
  4. Take the portafilter out, rinse the blind basket, lock it back in and repeat the same cycles with water only.
  5. Run the pump with no portafilter and brush the screen and gasket.
  6. Refit the normal basket. Pull one shot and throw it away, which re-seasons the group.
