Board hangs at Welcome-Melody

[CampoES]

Hi,
the board works fine at the beginning of the season this year. Because of vacation I turned the Pool off. After restarting the board hangs endless in the Welcome-Melody. Can somebody tell me what I should do now?

Thanks for your Ideas.

Pool: Bestway Miami
Board: I bought a "Ready to use Board" in 05/2023, Board: BWC v2 - 6 Wires

Check bootlog.txt if possible. Maybe you need to disconnect it from the pump to be able to. (And power it via USB)

Thank you for your post.

I log in over wlan, so this works.

bootlog.txt for 2025 gives:
{"BOOTINFO":"Power On 2025-05-10 14:17:46"} {"BOOTINFO":"Power On 2025-05-11 08:40:27"} {"BOOTINFO":"Software/System restart 2025-05-11 08:50:38"} {"BOOTINFO":"Power On 2025-05-11 09:08:05"} {"BOOTINFO":"Power On 2025-05-11 09:09:00"} {"BOOTINFO":"Power On 2025-05-11 09:20:55"} {"BOOTINFO":"Software/System restart 2025-05-17 09:59:12"} {"BOOTINFO":"Power On 2025-05-17 10:05:43"} {"BOOTINFO":"Software/System restart 2025-05-17 10:10:32"} {"BOOTINFO":"Software/System restart 2025-06-04 15:55:15"} {"BOOTINFO":"Power On 2025-06-04 16:10:55"} {"BOOTINFO":"Exception 2025-06-12 15:35:36"} {"BOOTINFO":"Power On 2025-06-13 12:27:07"} {"BOOTINFO":"External System 2025-07-28 17:15:37"}

Does this help to get an idea?

Well, it seems it only logged normal reboots, and not when it get stuck in a loop. But since it worked before, it's almost certain that there is corrosion or similar that is the cause. Unless cosmic rays reprogrammed the chip (it can happen but is not the most likely)

ok, pity. Thank you.
