If you need to gain access to the control board of your RHS18 softener, we're here to help. Let's get started!
1. First, you'll need to remove the top cover.
- You can do this by unhooking the back of the top cover near the inlet/outlet port. There are plastic clips on either side that hold the cover onto the salt tank below (1).
- Slide the salt lid up to look into the salt tank. Locate the two clips on the inside of the front tank wall. Unhook the front of the cover here and lift up, removing the entire top cover.
2. Next, you'll need to pull the faceplate housing straight up and out.
3. Go ahead and turn the faceplate housing over and unclip the faceplate enclosure. Now you should be able to see the back of the electronic board with the wire connections.
4. If you need to remove the control board, you're going to unsnap all four corners of the green plate and then you can lift it out.
