Dolphin Diagnostic
by: Peter

Hi, I have a Dolphin Diagnostic. When I turn it on, it will run for about 1 second, moves about 6" and then stop. The fan at the top does not spin during this time. If I turn the electrical box off and then back on, it will just do the same thing again. Unit is just 2 years old.
Thanks!

Dolphin Wave will not turn and only travels 15 ft back and forth
by: Frank

I bought a Dolphin Wave 65 last year and it worked flawlessly out of the box. This year it seems to stay in whatever part of the pool I put it in and only go back and forth for about 15 feet. It literally stays on the same line with no turns. The remote control turning controls won't turn it either. If I push right arrow it still goes straight.

It vacuums leaves and dirt just fine...I just have to constantly reposition it and this is not the reason I bought the unit.

I followed many instructions:
1. Moving the handle to opposite diagonal directions
2. SELF TEST by turning power off, turn dolphin upside down and turning it on. The treads move back and forth about 45 seconds and then it stops.
3. Filters are clean and everything seems to be in order physically. Again it is only a year old.

Thanks for your help.

Dolphin Nautilus stopped working
by: Cindy

I have had the Dolphin Nautilus for 1 week. Today I put it in the pool, it started normally, tracked up the side of the pool and stopped.

I unplugged it, took it out of the pool - the filters were OK, plugged it in again, put it in the pool and turned it on. It processes water, but does not move.

What to do next?

Dolphin Premier flips upside down.
by: Texas User

The fifth time I used my dolphin. It goes straight to the walls and tries to climb out of the pool. I reset it and it does the same thing. Most often the unit starts sucking in air, flips upside down and then float on the top of the pool eventually shutting down. I'm using the big refuse bag for the filter as I get leaves in the pool. What do I do?

Dolphin Premier 5M Robotic Pool Cleaner
by: Anonymous

Just received Dolphin Premier 5M Robotic Pool Cleaner and caddy today. Put caddy together and put cleaner in the pool. Turned it on and off it went! Only thing is one set of rubber tracks worked where the other set of rubber tracks was dead! I tried everything to correct it and even took plate off to check the rollers. It seems stiff and hard to rotate where the side that works seems more supple. Why do you think one side won't work? I'm so frustrated and disappointed.

Dolphin Deluxe 4 Power switch
by: Kennedy

We have a deluxe 4 that we purchased through Leslies Pool Supply. It has the basic power supply. Despite only being three years old, the power switch on the power pack has worn to the point you are lucky if you can get it to turn on or off. Is it possible to replace the switch with a toggle switch? And if so, any recommendations? Besides that the only other problem we have with our Dolphin is cord tangling. I am considering purchasing a replacement DX4 cord and ignoring the third post in the amphemol plug, or is there a swivel cable designed specifically for the Deluxe 4?

Dolphin Deluxe 4
by: Ken

Bought our Dolphin just 3 years ago, it has JUST run out of warranty, and it has JUST stopped working. The unit was working fine, then just stopped. I took the whole thing apart. Tested the power supply and it's outputting correctly. Tested the input at the motor, and it seems to be correct, but when I tested the circuit board in the motor, it seems power is coming to the board, but not going out to the motors. Is it possible to buy JUST the circuit board? If not, what's the next step. I do NOT want to have to buy a whole new motor. After only 3 years of use.

What type of remote control for a Dynamic 2002?
by: Vette

I got my hand on a used remote control (RC91752, black and. Green T-Type, says Maytronics 2002, Ver 65, ID. No. 03, after switch on). I tried to use it on my Dynamics 2002 (which has a 6H Dynamic DC motor unit installed). I can't get the Dolphin controlled trough the Joystick, it looks like the two devices aren't communicating to each other.
Questions 1: Are these two devices compatible, meaning should the work together?
Question 2: Do I have to configure the 2 devices, that they are able to communicate to together? (Matching ID's or somethng?)
Question 3: How can I do this? What are the steps to achive this?
Any answers more that welcome.

Correction, The distance between the inner center and outermost ring is 3/8 inch.
I tried to prop it up with some glue. I was thinking of cutting it between the smooth part & the threads, about 3/4 inch down the shaft.

This caused the pool cleaner to lose all power, as you can see, the outer connection is worn down.

Help, my pool is turning green!
by: JT

I purchased my 2nd dolphin cleaner last year. The first one lasted 10 years with no problems. The new one stopped working last week. I called Maytronics and was directed to a two page troubleshooting guide(worthless). When I turn the cleaner on the fan will run for 3 seconds, off for 3 seconds. After 3or 4 times the brushes will turn about 6 inches and that's it. Any suggestions? Is there an authorized repair company in the Maryland area? I took it to Leslie's Pool's where I purchased it but they don't service this cleaner.

Dolphin diagnostic ECB
by: Grant Cooley

I have a 2004 maytronics diagnostic which I purchased when my 2001 died. My 2004 quit working so I started trouble shooting both units. Power supplies on both are good, power cable on both are good, impeller motors on both are good, drive motors on both are good. When I opened the sealed unit on the 2004 unit I found R15 burned. If I jumper around it the drive motor will run, the impeller motor will run intermittent, the LED is blinking. The resistor appears to be a 6.51 ohm. Can I buys resistor or just send in the ECB?
On the older unit there is one large resistor which appears burnt, not sure of the value. Any way to get the ECB repaired or get a set of schematics?
After spending over $2,000 for the two of these, I really do not want to spend another thousand dollars when the total cost of repair parts would be less than five dollars

If your Dolphin moves a little bit and the impeller spins, but then stops after about 15 seconds it could be the graphite powder used on the motor getting onto the control circuit board.

Open up the unit and vacuum the circuit board to remove the graphite from the board. I had the same problem as you reported and when I did this the rover works and I have not had an issue since.

Need help
by: George Bradford

I've had my Dolphen for several years. It has always performed up to standard. There have been a few really minor issues that were quickly resolved by my son or me.

The other day it would not start. After inspecting the power cord, I discovered that the power cable had pulled away from the the cart. This is the end that does not go in the water, but screws into the cart.

There is a black receptical to which the cord is or should be attached. This receptical screws on to another terminal that is affixed to the cart, thus providing power to the Dolphen when switched on.

The electrical wires have come a loose and to reattach them seems a simple task. However, there is no code or diagram indicating to which of the little posts the Red, Black, and White wires should be be connected.

Can you provide me a diagram or explanation regarding the correct connection?

Greatly appreciate whatever help you can provide.

by: Anonymous

We have a Dolphin 3002 pro, it has taken to starting in the normal way but one side only starts slowly in one direction then stops. The other side works fine until the safety kicks in and the whole machine stops. I have taken off the side plate to check for debris, there is none. I found the bearings in one guide wheel had come apart so I replaced this from my stock. I then put everything back together to test but this has not cured the problem.

Any ideas?

Dolphin design flaw
by: Justindm1

I had an issue with the impeller spinning for 10 seconds and then never turning again until the unit was power cycled.

I think I have worked out the issue that caused this,which is that the carbon powder that they use on the motor gets out of the motor and onto the circuit board after a year or so. Every time you take the rover out and invert it to clean the bag you are shaking the powder around inside the unit.

When I opened the watertight box inside the cleaner I noticed a lot of the carbon powder on the circuit board. As carbon is a conductor I wondered if it was shorting the sensor circuit and so blew hard on the circuit board. When I power cycled the cleaner this time it started working normally.

If you have issues with your pool cleaner and have tried everything else then open up the watertight box and use a vacuum cleaner to such up any carbon on the circuit board and see if this fixes the problem.

Dolphin suggestion when the cleaner is being assembled when the wires to the circuit board have been attached a quick spray of polyurethane on the circuit board would stop this issue.

Suggestion
by: Warren Kiyabu

Please post your response to the individual questions online. I know you are answering the original person who asked it, but what about the new people with the exact same problem as a previous post. Same issue as this post.

I have a Dolphin Diagnostics Cleaner that has the Swivel Cable. Inside the swivel part of the cable there are three spring loaded pins that make the connection and allow the cable to swivel. The center pin on mine has lost its spring tension and every couple of weeks the unit stops moving and I have to open the swivel assembly and pull the pin out a little so that it makes a good connection. Is there somewhere that I can get replacement pins for the cable swivel assembly. It appears that they are easily replaceable if they were available.

Cable Plug into Power Supply Burnt Out
by: Anonymous

Hi, Thanks for your help. One of the male pins on the plug attached to the long cable has burnt out and broke off in the female plug on the power supply. It is the pin that connects to the white wire. I realize that only two of the pins are used and I've swapped the bad pins for the good pins. This doesn't seem possible on the male plug. Can you make any suggestions. Awesome product by the way. Hey, while we're at it, is there a way to make my old cable "tangle-proof" like the newer models?

Thanks again.

Please help me find parts

Looking to replace the two soft rubber blue pads that have 7 little pegs on one side and four rectangle molds sticking out on the other side. They fit on the pink plastic bracket around the bottom insides like a brush guard or something. They are a little under 8.5 inches long and 2 inches wide. Both fell off and will not stay in anymore.

tips
by: Anonymous

one thing to note, if the unit stop running and the power supply is on, usually the motor is the culprit, if the power supply is off then the power supply is usually bad. if both shut off then there is a short somewhere in the system.

stopped working
by: Maggie

I have just purchased the new power supply for the Dolphin diagnostic as my previous one stopped working. the new model has 4 small blue lights in the 4 corners of the power switch. The bottom right blue light is no longer lit when the unit is powered on plus the dolphin diagnostic is no longer working at all although it was working with the new power supply for about a month. Please let me know what to do and what may be wrong now. Thanks,

My Dolphin Is Sick
by: Randy z

Hi, I have a Dolphin Diagnostic. it has been working fine but recently stopped working. When I power it up it moves a little bit reverses then stops. I have been told that it may be the board inside the robot. can you tell me if this is the problem? Or where can I bring it in my area for repair? and is this an expensive repair, as the unit was costly to begin with, I don't want to be shocked by a large repair bill.
i am in the 07827 New Jersey area.
Thank You

time limit in water?
by: Anonymous

Is there any maximum amount of time that a Dolphin pool cleaner can be left in a pool? Do i need to remove it every so many hours to let it dry out? Someone told me that the warranty would not be any good if I left the dolphin in the pool for too many hours, but I can't find any information about this. Thank you for your advice.

My dolphin has stopped working
by: Gordon

I have a Dolphin Dynamic. I don't remember precisely when I bought it but I would estimate it to be about 3-4 years old. In the past year it has started to operate poorly. Currently, when I turn it on at the caddy, it goes through its normal start up routine (pivoting then setting off in a straight line) and runs for about 30 seconds, making perhaps two passes. Then it slows down, the impeller stops turning, it keeps crawling along at a slower and slower speed and then stops. If I turn it off for a minute then turn it back on, it does the same thing -- runs for less than a minute then stops. I have cleaned the bag and washed it in the washing machine as recommended by Dolphin USA Customer Service. I have checked the tracks and interior for any blockages or foreign objects. Everything looks clean. What could the problem be? I only use this machine for a few months of the year, and not very often at that. I have a weekly pool service that vacuums and cleans my pool. The unit is stored in its caddy under a roofed pool cabana and we live in California where it is not subjected to freezing winter weather. Total hours of use on the system aren't that many. Surely your product should last longer than this? Can you please help me with this?
Thanks!

Dolphin impeller not moving
by: whitesbj

I have a 4 year old Dolphin Diagnostic, starting last year it would start to move and the impeller would start sucking water, but after a few minutes it would stop sucking water and try to climb the side wall over and over for hours but could not because there was no suction from the impeller. It is now basically useless.

Impeller not clogged but not turning
by: Anonymous

My Dolphin Diagnostic Advantage would make a little move forwards then a little move back and stop. I checked the drive train and it was basically clean. Now it runs longer 6-8 feet and stops. I noticed the impeller is not spinning. I don't know if it was originally, but isn't now and isn't clogged.

Is this a repairable problem?

Fuses

The older power supplies, may or may not have a fuse housing depending on what circuit card is inside the unit. Most of them have a fuse, which is accessible on the outside rear housing of the power supply.

Diagnostic
by: Bob

I have a 3h Diagnostic DC drive unit that will go into what I think is a start up test and runs for about a min. When I turn it on I hear the relay click then the fan runs for about 2 sec then the fan and the drive moter turns on going one way then the other.This goes on for about a minute then I see that the drive motor slowes down a bit on its turning but turns for about 30 sec and then stops. I have 38 volts on the main wires going to the control board.The motores are running about 25 volts on them. When the drive motorstates out on it run the voltage dropes to 11.5 volts.where do you think the voltage drop is comming from. What do you think i should do?
