2020 Giant TCR Advanced Pro. I washed the bike and per the title, the right side power reading has gone to zero. The right side still lights up and charges, and I was able to use RideLink to update firmware, but I cannot calibrate (fails with error 000ee22 in a message box). It still gives power readings, but they're about 4-5x too high, and left-sided in the power balance.
Given it is just a lump glued to my crank, I can't really think of what to try. It was supposed to be ipx7 waterproof! Anyone have any ideas?
[unfortunately I am the second owner and Giant Australia have previously told me I have no warranty and should've bought new and supported the brand]
Edit: The first ride was about 3 days after the wash, and it read 1000w on one side, after about a week it started giving some readings on the other side, but still inflated altogether; and finally on day 10 I gave it 5 minutes with a hairdryer on low and tried a ride and it read totally back to normal! It's a sealed unit glued on to the crank, so there's nothing I could do apart from just give it time, and the hairdryer. If this happens to you, hold out hope for at least 10 days to see if it finally dries out unharmed.
