I had the exact same thing happen on my game. It turned out it was a short caused by a loose wire on a completely different switch. Check underneath the entire playfield carefully to see if you can find something obvious.

I would go into switch test and hit both and see if your slam tilt switch is closing.

Be sure they are wired right. Check other stand up targets in your game. White wire there, green wire there, which way silver band end of diode goes that way. Same on every switch.

White Water is susceptible to resets when these are wired wrong.

I had the same thing a few years ago on my WH2O as well and it was caused by a single strand of wire from another standup target causing a short. As Gweempose stated, be sure to carefully check the wiring on all of your standup targets to verify that you don't have a stray wire causing a short.

On both switches, solder the WHT-XX wires to the non-banded side of the diode

When in doubt, look at all the other switches in the game to double check if you're doing it correctly. They are all wired the same.

Wish I had searched for this issue sooner. Fixed my issue after years of headaches.
