The purpose of this procedure is to remove the filter reminder beeper alarm
that will sound even upon clearing the faults. This is due to some poor workmanship or poor quality parts used by GE. First see if GE will repair or replace the parts under your warranty. If you are like me, I was out of warranty and found that the heater operates fine except for the annoying beeping every 30 seconds. Many owners of this water heater are fully aware of the issue, but I had not seen this procedure anywhere on the internet so i figured I'd share what I did. In the end, you still have the filter light flashing, just no sound coming from it.
Step 1: Shut Off Power and Remove the Control Panel
Safety first: shut off power to your water heater at the circuit breaker. and verify the unit is off. Then remove the one screw shown and remove the control panel. You need to slide it downward then it swings out. Rotate it to completely remove the pivot points from the heater opening.
Step 2: Test for Power, and Open the Control Panel
Use a non-contact meter and verify there is no power in any of the wires entering the panel. Remove one screw on the top to open the metal back cover.
Step 3: Unplug the Wires From the Outer Board
Unplug the small wires by gently grasping them and pulling straight off. Firmly grip the connectors of the heavy wires with pliers and pull them off their connectors. Only the heavy wires exiting the panel need to be removed, as shown in the picture in the next step.
Step 4: Remove the Outer Board
Gently pry the plastic tabs to swing the outer board out of the way to access the inner board.
Step 5: Remove the Inner Board
Remove two screws securing the inner board. Then gently release the tabs holding it in place. You should be able to remove both boards now.
Step 6: Pry Off the Piezo Disc
Use a small screwdriver to gently work the outer cap off the piezo beeper. Once removed, you can decide where to save the metal disc in case you ever need to reinstall it. Removal will likely void any warranty you have so it might be smart to hang on to it. At this point, you have disabled the beeper, and all that is left is to reverse the other steps to reinstall the circuit boards and reconnect all the wires on the proper terminals. Be careful to match the proper color wires where they came from following the colored paint dots.
