After disconnecting the power and turning off the water, I removed the bottom skirt piece and sound insulation. With the door open, I removed the two screws at the top that were holding the unit in place. Then the unit could easily be moved out from underneath the counter.
With towels on the floor, I gently put the unit on it’s left side which gave me easy access to the pump. A thin screwdriver head was used to carefully disconnect the plug from the pump. I then used adjustable pliers to remove the clamps from the inlet and outlet of the pump, which was then easy to remove from the unit.
Putting the new clamps provided first, I then reassembled the unit. This was a little tricky as it required more or less simultaneously inserting each end of the pump and sliding the unit bracket arm into position. I then tightened the clamps securely, and reconnected the electrical plug to the pump.
I then stood the unit upright, and since I had adequate power cord and water connection, I was actually able to rest run the unit before returning it to its place under the counter. To my profound relief, the unit didn’t leak and ran like new!
After running it for a cycle I slid the unit back under the counter being careful not to damage the insulation, reattached the top screws securing it, and replacing the original sound insulation and skirt plate. All-in-all, it took about two hours, including waiting for the 49 minute “light” cycle to run.
