Instant pot Pro Plus stuck on Preheat

I have got an Instant pot pro plus. It's been 2years 6months of no issues.

Recently it been acting weird. It would build pressure correctly, but never leaves the Preheat section to the timer part.

I do not see or hear any pressure leaking. But, replaced the sealing ring, pressure valve, float valve and all the silicone that is in there.

Still no luck.

It goes into the timer in every other setting that does NOT involve "pressure".

Searching on reddit, YouTube, Google and chatgpt has not helped.
