Ajuste de dureza del lavavajillas: todas las marcas

El lavavajillas descalcifica con sal y resina; el ajuste de dureza indica cada cuánto regenerar. Si es bajo quedan restos de cal en los vasos; si es alto se desperdicia sal.

Las tablas proceden del manual de cada fabricante para la gama indicada debajo. Busque la dureza de su ciudad y luego su marca.

Miele

Water hardness level, set in programming/commissioning menu in deg dH (G 7000-series with AutoDos)

En Miele se introduce la dureza directamente (1–70 °dH): ponga los °dH de su agua (°fH ÷ 1,785).

Cómo cambiarlo: At first start-up the display shows the water hardness screen: select your level and confirm with OK; later via Settings > Water hardness, select level, confirm OK. If hardness fluctuates, set the higher value (example in manual: 10-15 deg dH -> set 15).

Sal: Water softening needed above 0.9 mmol/l (5 deg dH). If water is constantly below 0.9 mmol/l (5 deg dH) no salt is needed and the salt indicator switches off when the hardness is set accordingly. Combination detergents can replace salt below 3.8 mmol/l (21 deg dH).
