Cleaning and Maintenance

Deliming

Minerals accumulate on the interior surfaces of the dishwasher. The deposits have a white haze and, in cases of heavy accumulation, may appear as a granular solid. The generic name for mineral deposits is lime. The removal of lime deposits is called Deliming. Your dishwasher should be delimed regularly; how often will depend on the mineral content of your water.

Inspect your machine interior for lime deposits. If deliming is required, a Deliming agent should be used for best results in accordance with the chemical supplier's instructions.

DANGER:

Death or serious injury may result when Deliming solution is mixed with sodium hypochlorite (chlorine bleach) sanitizing agent. Mixing may cause hazardous gases to form.

Deliming solution and other acids must never be mixed with chlorine, iodine, bromine, or uorine.

CAUTION:

Skin contact with Deliming solutions can cause severe irritation and possible chemical burns. Always wear protective clothing and goggles when handling chemicals.

NOTE:

Contact your chemical supplier for specic safety procedures and instructions for the use of the Deliming solution supplied for the dishwasher.

Deliming solution or other chemicals are not supplied by the dishwasher manufacturer.
