About

Hybrid Heater Codes explains the error and alert codes that heat pump (hybrid electric) water heaters show on their displays.

Where the answers come from

Every code, troubleshooting step and maintenance task on this site is taken from the manufacturer's own Use & Care manual, installation manual or support documentation. Each page names the document and the page number, with a link, so you can check it yourself. We do not add our own guesses to a manufacturer's instructions. When a manual says to call a qualified technician, so do we.

What we don't cover

If a code is missing, the manual we have for your series doesn't list it. Codes change between generations, so match the model number on your heater's rating label to the series name. Tankless and gas water heaters are not covered.
