Limescale formation is a normal occurrence when using your coffee machine and will result in reduced water flow or cold coffee. For this reason, you will need to descale the machine every three months or so, and in any case everytime the descaling light on the appliance is switched on (for machine models equipped with descaling alert). If you live in an area where hard water is prevalent, then the descaling maybe required to be completed more frequently. Lavazza assumes no responsibility for damage to the machine resulting from failure to descale.
To complete the descaling process, use a non-toxic and/or non-harmful type of descaling product for coffee machines, commonly available on the market.
Do not drink the descaling solution and liquids that have run through the machine until the cycle is complete.
Never use vinegar as a descaling agent.
