Hitachi 01101 fault code

What it means

Fan stop for strong wind (code 11)

A PROTECTION, not a failure: strong wind spun the outdoor fan backwards / disturbed its control, so the unit stopped it to protect the motor. It normally recovers on its own once the wind eases.

UK models this code applies to

From the Hitachi service literature we hold (Hitachi Technical Catalogue §9.10 / §10.1.2 Error Code Information (RAK-PSES(W)/RAC-WSE — Hitachi UK; RAK-PED/RAC-WED — Hitachi R32 catalogue), both render-verified) — not a scraped list.

Now the harder half: proving what caused it

01101 names a symptom, not a root cause. In the app, the same code opens a guided investigation: what to measure first, the expected values for your exact model, and an honest verdict — including “nothing in this machine is broken” when that's what the readings say.
