It is important to press and hold the start/stop button for at least 5 seconds to start the descaling program.The descaling program now starts and the descale
lights will flash.The process takes around 30 minutes while descaling solution is slowly pumped through the system and then runs into the container until the water tank is almost empty. A little liquid is always left in the tank.Note: If the process only takes a couple of minutes then you may have run a cleaning cycle by mistake - the machine will not be fully descaled and the red descale light
will remain illuminated. If this occurs go back to step 6.
