Here are the steps to replace the pump:
1) First remove all of your plants from the Gardyn and turn the power switch to the off position (o). Unplug the power supply from the back of the Gardyn, just as you would with changing the water in the tank. Put the water pump in the up position.
2) Open the lid lock latches, and remove the columns & lights assembly from the base and place on a towel.
3) Carefully place the Gardyn on the floor so the columns are on the floor and the lights are above it. This will give you access to the underneath, where you can remove the original pump and install the new one.
4) Follow the black & red wires to where they go under the lid. You will see a foam insert that you will need to remove.
5) After removing the foam insert, use tweezers to pull the internal wiring connection out from the plastic housing. Please note that you want to be careful to not detach the white connectors. If they female connector side retracts under the lid, you can use tweezers to pull it back out.
Once the wiring connection is pulled out from under the plastic house, place the foam insert back to prevent the wires from retracting back underneath when you disconnect the wires.
6) Now, you will need to disconnect the white connectors of the pump.
7) Once that has been completed, slide the pump holder off the original pump and put it on the new pump.
8) Now you are ready to connect the wiring to the new pump.
9) Be sure to align the two wiring connectors, with the plastic tabs and colored cables matching, like shown below.
10) Reinsert the two connections back into the lid housing, and replace the foam insert.
You are now ready to put carefully stand the Gardyn back up and place on top of the tank.
