The top cover provides a housing for the control board, and protection for the electronics and moving parts. Sometimes, it can be tricky to remove it. The following steps below should be helpful if this is your first time learning how to remove it.
- On the back of the unit, you'll unhook the two clips that hold the cover onto the tank below (see photo). Flex/pull the cover out and away from the unit at these clips.
- There are two similar clips holding the front of the cover on as well. You'll need to slide the cover towards you to release these clips, being careful not to disconnect any wires. It's normal for the plastic cover to produce some noise as it shifts and bends.
