4.3 Deliming Schedules
Your dishwasher should be delimed regularly depending on the mineral content of your water. Inspect the
machine interior for mineral deposits and use a deliming solution for the best cleaning results.
WARNING:
Deliming solutions or other acids must not come in contact with household bleach
(sodium hypochlorite) or any chemicals containing chlorine, iodine, bromine, or fluorine.
Mixing will cause hazardous gases to form.
Skin contact with deliming solutions can cause severe irritation and possible chemical burns.
WARNING:
Consult your chemical supplier for an appropriate deliming solution,
protective gear and safety procedures.
