Is 086 on a A.O. Smith heat pump water heater an emergency?

Usually not an emergency. If it smells like burning, sparks, or trips the breaker, switch it off at the breaker and leave it off until it is checked.

What 086 means

“Fan speed feedback”

— A.O. Smith, A.O. Smith Hybrid Electric Heat Pump Water Heater Service Handbook. Codes vary by model: check your heat pump water heater’s own manual.

Where 086 fits

In plain words, 086 is about a motor or fan — it did not turn, turned the wrong speed, or the load is unbalanced.

Next to 086 in A.O. Smith’s table: 084 (Heat Pump Compressor is not functioning).

What to try first

  • Call a qualified technician.

Safety: If it smells like burning, sparks, or trips the breaker, switch it off at the breaker and leave it off until it is checked.

How urgent is it?

At least THIS WEEK. fixRAgent treats this code as a this-week repair: the appliance has reported a fault, but the code alone does not point at a safety hazard. This is fixRAgent’s reading, not the manufacturer’s. A photo can raise it — water near wiring, scorch marks, a gas smell — but a code never lowers what the photo shows.

Who to call

Plumber. Have the model and serial numbers from the label ready — a photo of the label works.

Recalls and manuals

Check whether your model is under a safety recall on the U.S. Consumer Product Safety Commission’s site: cpsc.gov/Recalls. Your owner’s manual is on A.O. Smith’s support site; search it with the model number from the label.
