Sub-Zero Repair in DuPont

What we see here

1. 01 With chlorine as the city's only treatment, the cartridge in the Sub-Zero may be the only filter between the city main and the ice.
2. 02 Groundwater from deep aquifers carries dissolved minerals, and the city's water page gives no water hardness figure, so a test is what settles whether scale belongs on the list.
3. 03 An ageing cartridge can slow the fill, and a slow fill tends to show as smaller or hollow cubes before the bin runs empty.

On your side of the Shut-Off Line

1. 01 Look at the kettle and the tap aerator for white crust, and say what you find; the city publishes no hardness figure.
2. 02 Note how old the cartridge in the Sub-Zero is, because on DuPont water it may be the only filter between the city main and the ice.
3. 03 If the cubes shrank gradually rather than stopped, say so; a tired cartridge slows the fill long before the bin runs dry.

Then the five that apply anywhere, in order: switch, filter, supply valve, fill tube, arm and bin.

Booking

When you book, name your neighborhood and say whether a softener or filter has been added to the house supply.

The $89 visit pays for the trip and the whole diagnosis, and once you approve the repair that $89 is deducted from its price. The phone is answered 24/7; visits run 8 am to 8 pm, Monday through Sunday.

What the visit covers is on the Sub-Zero ice maker repair page. On this water, read Why Is My Ice Cloudy first.
