Parts are in, Dolphin Has Been Repaired, Cleaning Away

Let’s take a closer look at the process. Upon further inspection, I found corrosion around the motors. The seal around the power cord also appears to be in poor condition. So, I proceed with a teardown, replacing the power unit, and tread ball bearings to restore the robot back to full capacity with genuine OEM parts. A self-test  was performed as need, I conducted a number of in-water and out-of-water tests which worked perfectly. As it should, under normal power. Next, I replaced all parts and picked up where we left off on the last article Nautilus Down (check that out if you missed it).

Pre-Check, Install and Test

Check all cogs, ball bearings, drive pin, and wheel/hub parts. Make sure ball bearings are moving freely and free of rust or degradation. Replaced any parts showing degradation or major rust. Filled electronic parts and pressure seals with pool lube and reconnected parts, careful to screw-down fasteners and plastic nuts with appropriate tension. Dolphin On. Additionally, both out-of-water and in-the-water tests performed as expected. Time for a swim! Cinched down any screws, or screens, package up the robot and ran the clean cycle.

Brush Down and Toggle The Dolphin On

If you can’t tell, the pool has sand, debris and dragonflies. Before we toggle the Dolphin On, let’s do a quick brush down of the pool to encourage removal.  You can kind of see here the pool was a bit dirty,  as the hurricane kicked up enough debris for the Dolphin to clean. There was no pool cage carnage, or aluminum part failure, which is great. Minor screen damage only.

Maytronics Documents and More

Finally, following the test cycles, Dolphin on, put in the water and cleaned the pool well. In most cases, the vacuum actively cleans on stage 1, please the Maytronics manuals. Find Stage 1 testing and more robot testing features under the Nautilus CC Plus section. I hope this information helps, how to get your pool robot fixed and Dolphin On. If anyone out there needs assistance, please contact me I am happy to help. Thanks! As usual leave a comment below to let us know what you’re thinking!

Nautlius Motor Troubles

Lab Work – Maytronics Repair, Dolphin Down. Let’s fix the Nautilus CC Plus

Looks like a new motor unit is required. Full teardown ahead.

Exciting news! A new series, Dolphin Down, is coming soon. This series is related to the repair of the Maytronics Dolphin Nautilus CC Plus. Currently, we are awaiting the arrival of a new motor unit. In the meantime, we are in the process of dismantling the Nautilus CC Plus robot in search of a malfunctioning drive motor.

The fan motor is functioning properly, passing both tests passed – underwater and out-of-water tests. The multimeter has confirmed that the drive motor is not working. The circuit board appears to be in good, working condition confirmed by the blinking green LEDs. The LEDs indicating that it is functioning as expected. This a positive sign for our robot and the repair diagnosis.

To begin the teardown process, find a safe spot and grab a multi-tool with pliers, flathead and cross bits (Phillips bits). Start by removing the power cord from the unit and unplugging the unit from the wall if necessary. First, on the Dolphin, unscrew the four screws under the filter doors to remove the top. Use the transparent or white flathead key or knob to pop open the propeller gate, which is easily accessible once the filter doors are open.

Next, slide the cord out from under the blue, body cover after removing the four main screws. Adjust the cord, remove the floats and be careful when removing the side panels. These panels should just pop off top down.  Just be aware of the tabs on the bottom of the panels, this is what hold the body shells in place. Use the pliers to unscrew the blue cord connected to the power unit, as well as the four screws holding the two yellow cord strips to the unit. Unscrew the four unit screws holding the motor unit in place and it will be free.

Finally, check all cogs, drive belts, and wheel/hub parts. Ensure that the ball bearings are moving freely, unobstructed and are free of rust or degradation.  Replace any parts that showing degradation, wear or significant rust. Fill with lubricant and reconnect parts, being careful to screw with appropriate tension. Test the robot out of water first, followed by half-submerged and fully submerged underwater tests. *Updated – Check out the repair – Dolphin On or the first post we commented on regarding the Maytronics Nautilus Dolphin for more information on troubleshooting, maintenance and repairs. More information will be provided in the next *5 business days, as we will be receiving the new motor unit packaging up the robot and running the cleaning cycle. Thank you.

Hack-a-thon, Patching eMax TH2

Lab Work – eMax Quad Motor Rewire Video

After the crash, the eMax TH2 needed a new Flight Controller (FC) or FC Board, motors and fan blades. A quick peek underneath, revealed that everything was good as new with the new FC, motors, copper leads, LED’s, and alarms all working as expected. 

Time has  moved on since this original video post, I wanted to share other Emax content where applicable. If you’re looking for Emax content,  give these a shot (in reverse order from this postings date) – Emax FC, Emax Fix Part 1 and Part 2, Quadcopter Rewire video (this post), and the TinyHawk 2 mini project.
