The descaling process takes around 20 minutes while the solution is pumped through the system at intervals, and then runs into the container until the water tank is almost empty. A little liquid is always left in the tank.

If this occurs go back to step 6.

    The Status light comes on after 20 minutes to indicate that the first stage of the process is complete.
