Cleaning the ProVari circuit board after a juice spill:
Some of the symptoms of a wet circuit board are random error messages such as E1, E2, E4 and E8.
If you accidentally spilled lots of juice on the ProVari and it has run down the side and in through the button location or window area, it's possible some juice got inside the device.
This can cause random error messages that you didn't see before or if all of your atomizers and cartomizer are reading 1.3 ohms or any other strange behavior, you might need to clean the unit.
Please note: the top cap of the ProVari is sealed so typically juice will not get into the unit from the top.
We have had users report that they were using a tank and it leaked along the side of the device, this is the situation most likely to cause juice leakage into the ProVari.
This is a very easy procedure:
1. Remove the battery
2. Using some 99% isopropyl alcohol, pour a small amount into the tube so it goes down where the circuit board sits.
3. Gently shake the device so the isopropyl alcohol swirls around inside the tube.
4. Now pour it out and let the unit dry.
5. It's important to let it dry completely before installing the battery again.
It's a good idea to leave the end cap off and leave it overnight to dry. Then try again.
If you cannot find 99% isopropyl, you can use 91%.
91% has more water, so it will just take a little longer to dry.
If you use some canned air or an air compressor you can blow out the excess isopropyl and it will speed up the drying time.
