Risk of damaging the machine due to excess salt
Salt is highly corrosive and could cause damage.
– Use the funnel to direct the salt into the tank to avoid spilling
salt into the tank.
– Immediately wipe off any excess salt with a damp cloth.
c) Open the dishwasher door and fill the salt container with dishwasher
salt until the water overflows from the container (a full container
lasts up to 3 cycles).
