Turn off power at the GFCI before beginning this repair procedure. You will also need to remove the front equipment door so you can see the box which houses the circuit board.

Step 1: This is what an M-Drive
Upper Control Panel looks like.
Step 2: Most of the silicone
holding the panel down is
under the left side. (See Step 3
before proceeding). Using a
flat head screwdriver slide the
end under the M-Drive panel
in several different locations,
lifting up each time. If you push
the screwdriver down, you will put indentations in your spa shell,
or maybe even crack it. Remember to always lift up on the
screwdriver during this step. When it feels like the left-hand side is
beginning to loosen, use your screwdriver to pry the rest of the panel.
Be patient, this can take a few minutes.

Step 3: When you have broken
the adhesive seal, separate the
M-Drive Panel from the spa shell.

Step 4: Follow the cord from
the M-Drive Panel and find where it
plugs onto the printed circuit board.
Remember where it is, and how it is
plugged in.
Now, unplug it. Feed the end of the
cord and connector out of the equipment box.

Step 5: Tie a piece of 4’ sturdy string just below
the connector.

Step 6: From the top of the spa,
begin to pull on the cord, and
then the string; to remove the
cord and connector.
Step 7: Remove as much silicone from the spa shell as possible.

Step 8: Using your new M-Drive
Panel assembly, plug the connector
directly onto the circuit board. Turn on
the GFCI so the spa will start-up. It is
safe to hold the panel in your hand as
you test the buttons to insure your new
M-Drive works properly.

Step 9: When you’re satisfied your new panel
operates correctly, turn off power at the GFCI
and unplug the connector from the circuit board.
Untie your string from the old panel, and then tie
the string just below the connector on your new
panel.

Step 10: Carefully pull on the string
and feed the cord and connector
through the spa body. Replace the
connector back to its original position
and plug it onto the circuit board.

Step 11: Remove the paper liner
as shown.

Step 12: Using your old M-Drive Panel
as an example, apply LOTS of silicone in
the same places. Apply a liberal amount
around the cord area.
Step 13: Carefully position your
new M-Drive Panel and press into
place. Remove any excess silicone
to make the spa look like new. The
silicone takes 48 to 72 hours to
cure. Using a few tennis balls, or a short piece of 2 x 4, prop up the
cover near the M-Drive Panel to help the curing process.
