Daikin Mini Split E8 Error Code

What E8 means

E8 means an input overcurrent detection: Daikin service manuals (FFQ15Q2VJU, FVXS18NVJU) describe E8 as detected by checking the input current value against the allowed range, and Daikin's own self-diagnosis table reads 'malfunction of power supply or AC input overcurrent'. Daikin India's official table lists E8 as 'overcurrent input'; inverter-series rows also apply it to overcurrent of the inverter compressor. Typical drivers: brief power events/brownouts, loose power connections or reactor problems, inverter/IPM protection, and compressor faults after power checks pass.

First checks before service

This page currently documents the safe reset triage. If the code returns, use the linked source manual or a qualified technician for code-specific diagnosis.

1. 1. One-time fault event (power disturbance or transient sensor reading) common DIY

   Check: Power-cycle at the breaker/disconnect (or unplug for CPAP), restore, and run the system while watching for the code.

   Fix: If the code does not return after a full run cycle, the fault was transient — monitor, no repair needed.

2. 2. Fault persists after a clean reset occasional pro only

   Check: If the code returns immediately or every session, note the conditions (startup, heating, after rain).

   Fix: A persisting code points at the component the manual assigns to this code — that repair is technician territory.
