How do I adjust the water hardness level?
To change the default setting of water hardness (which is set to level 3), go into settings menu, navigate to „WATER HARDNESS”, use „<” or “>” buttons. Confirm your choice by pressing „OK”. Consult water hardness table on page 4 for setting based on your local needs.
