Cove Dishwasher Repair

Gritty dishes are usually the filter or the spray arm, not the pump. Our water runs 16 to 28 grains here, which is very hard, so the little holes in the spray arms scale shut and the arm stops reaching the top rack. Standing water in the bottom is a drain problem, often the air gap (the little cap next to the faucet) or a kinked hose under the sink.

Cove is the Sub-Zero Group's dishwasher line, launched in 2018. The most practical thing to know is that it's still new. Every unit in homes today has only a few years on it, so the problems we see lean toward installation and early-life issues, not wear. Drain hose routing, leveling, water supply and door alignment cause a good share of the calls. It also means fewer independent shops have worked on many of them. Fixing one takes knowing the machine, not years of seeing the same repair over and over. Parts come through the Sub-Zero Group network, the same channel as Sub-Zero and Wolf. Availability is reliable, and a tech who already works on those brands isn't learning a new parts supply. They're built to Sub-Zero Group standards and built to last, so on a unit this young, repair is almost always the right call, not replacement.
