Maintenance water softener
Leventi advises to always apply a water softener. This will
prolong the lifespan of your oven (and particularly the
boiler versions).
When you have connected your oven to a water softener,
then on average this should be descaled at least every
two weeks to ensure a proper working. Therefore follow
the operation manual of your water softener.
