Sub-Zero Repair around Lake Tapps

Ask your water utility

Lake Tapps is a reservoir. It was built for hydroelectric power and now belongs to the Cascade Water Alliance, a group of King County municipalities, as a drinking-water supply.

Most of the land around it is unincorporated Pierce County and some is inside the city of Bonney Lake, so the utility on your bill, not the lake, tells us what feeds the ice maker.

What we see here

  1. Sub-Zero built an outdoor version of its UC-15I, the UC-15I(P)O. Its installation guide requires a GFCI when it is installed outdoors and advises against one on the indoor model.
  2. Sub-Zero's troubleshooting for its undercounter ice maker warns that room heat and direct sun melt stored ice quickly, because the bin is not refrigerated. On a sunny deck, a low bin may be melt rather than a fault.
  3. A Sub-Zero has no shut-off valve inside it; the plumber fits one on its water line. A house with a second kitchen or a bar therefore has two valves to find.

On your side of the Shut-Off Line

  1. Reset a tripped GFCI outlet or breaker once if an outdoor machine has gone dark; if it trips again, stop there.
  2. Shade an outdoor machine from strong afternoon sun, then see whether the bin holds its ice; the bin has no cooling of its own.
  3. Find the valve on every line that feeds an ice maker, including a second kitchen or a bar, because a Sub-Zero has no shut-off inside it.
  4. Read the utility name on your bill rather than going by the lake: the shoreline is split between the county and Bonney Lake.

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

  • Cubes came out hollow and milky for weeks. He checked water pressure first, then found the fill tube half blocked with scale. Descaled and adjusted, and the cubes are clear again.

  • Glass door fogged on the inside and stayed that way all autumn. The door heater had gone open circuit. He tested it cold, replaced it, and the glass has been clear since.

  • Vacuum door kept popping back open a second after closing. The gasket had a split along the hinge side you could only see with a torch. New gasket, and it seals properly now.
