About the Bosch Purion, Intuvia, Kiox and Nyon (before the smart system)

Bosch prints this same table in the Purion (BUI215) MY2023 US manual (pages English 12 to 14). source
The same table is in the Intuvia (BUI255) MY2021 US manual (pages English 15 to 17). source
The same table is in the Kiox Online Version (BUI330) MY2020 US/CA manual (pages English 35 to 38). source
The same table is in the Nyon Online Version (BUI350) MY2021 US manual (pages English 66 to 69). Bosch notes code 430 does not apply to the BUI350. source
These displays belong to Bosch's older eBike system, not the smart system. The Bosch smart system (for example the Purion 200 and Kiox 400C) uses six-character error numbers instead. source
Bosch also lists "7xx" for faults in third-party parts, and "Display is blank" for an internal fault of the on-board computer. They are not single codes, so they are not in this list. source

In plain English

This code points to the power button or keypad. Bafang's E162 manual says holding the power button while the display turns on triggers it, so release the button first. A stuck or wet button pad is the next most likely cause.

Step-by-step checklist

Work from the top. Steps go from free and easy to shop jobs. Switch the bike off before touching any connector. Tick each step as you go. Your progress is saved on this device.

1Release the power buttonFree Make sure you're not still holding the power button as the display turns on. Release it and see if the code clears.
2Turn it off and on againFree Switch the display off, wait 30 seconds, then switch it back on. If the code clears, note what you were doing when it appeared, in case it comes back.
3Check for a stuck buttonEasy Press each button on the handlebar pad a few times. A button stuck down by dirt or water can send commands non-stop. Clean around it and check the pad's cable and plug.
4Have the controller testedShop job If the wiring checks out, the controller may be faulty. A shop can test it and replace it if needed.
