Navien tankless water heater code E060
Dual venturi fault. Code E060 means the same thing on all 2 Navien series documented here — but the fix, and what it costs, is still worth reading for your exact unit.
What code E060 means on each Navien series
| Series | What it means | Verdict | Typical cost |
|---|---|---|---|
| NPE-2 | Dual venturi fault | Call a pro | $200–$1,100 |
| NPE-A / NPE-S | Dual venturi fault | Call a pro | $200–$1,100 |
Each row opens the full page for that generation. We hold manuals for NPE-2 and NPE-A / NPE-S, and each one gets its own reading of code E060 — what Navien documents, what you can safely check yourself, and what the repair should cost.
What each manual actually says
The table above compares 2 series in four columns, which is enough to route you and not enough to explain anything. This is the Navien wording behind each row, one entry per manual, so you can see where the 2 readings of code E060 agree and where they part company.
NPE-2 — Dual venturi fault
The venturi is the throat where combustion air and gas are mixed; the NPE uses a dual venturi arrangement, and this code says it is not behaving. Navien lists no owner-level check — contact technical support.
NPE-A / NPE-S — Dual venturi fault
A fault in the dual venturi, the assembly that meters the air and gas mixture going to the burner. Navien's instruction is to contact technical support; there is no owner-side check.
Does it matter which Navien you have?
NPE-2 and NPE-A / NPE-S all route code E060 the same way: a professional, at $200–$1,100. That makes it one of the Navien numbers you can act on before working out which unit you own.
What to check first, whatever your series
These checks are on the manufacturer's list for every Navien series that reports code E060, so they are safe to work through before you have identified your exact unit. They also cost nothing.
- If you smell gas, leave the building and call your gas utility from outside.
That is 1 of the 3 checks documented for code E060. The rest differ by generation, so if none of those explains it, go to your own series above.
