Do all AQUA LOGIC boards have a Varistor?

[maxepr1]

Having issues with my system again. This time "LOW SALT" with CHECK SYSTEM light on. I soldiered the leg on the K1 relay a few years ago for a NO FLOW issue. Worked fine until now. Don't see any Varistor like everybody seems to replace? Going to get the cell checked at the store, it is 4-5 years old. My PN on my board is g1-066008g-1 REV.G. My test strip readings are all over the place but each is above the 3000 level. The Varistor in a different place on this board? Thanks

I think only the AquaRite units have the Varisitor.

I would check the solder joint again.
