Haier Refrigerator E0 Error Code

Communication error between boards on Haier refrigerators.

May need a pro

E0 is Haier's code for a communication error. Parts of the control electronics have stopped exchanging signals with each other. A loose plug on the wiring between them or a failed board can cause it.

Compatible models

Haier doesn't tie E0 to particular models. It only says that each series displays its own set of codes, so look yours up in the manual.

Also shown as

Haier lists E0 as a communication error on its international support pages and doesn't say which boards are involved on each series.

Difficulty

Try the basic checks, but the usual fix is a technician's job.

Safety first: unplug the refrigerator (or switch off its breaker) before touching filters, hoses or panels. If you smell burning or gas, or see water near the outlet, stop and call a professional.

How to fix Haier E0

Restart the fridge
Unplug it or turn off its breaker for a couple of minutes, then plug back in. A glitch after a power surge sometimes clears this way.
Watch whether it's cooling
Even with a communication fault the fridge may keep running. Check the thermometer readings over the next few hours to see whether food is still safe.

When to call a technician

If E0 returns, call Haier service. The fix involves the wiring and boards inside the cabinet, which aren't owner-serviceable.
