What do you do when your Maytronics Dolphin Pool Cleaners stops running or there are no lights on the Power Supply? This guide shows you how to troubleshoot the electrical circuits of the Maytronics Dolphin Pool Cleaners so you can isolate your problem and replace the failed parts or parts. Our primary tool for testing these electrical circuits is a multimeter/voltmeter so we will first cover some of the basics of how to use a multimeter.
DIAL METER FOR AC TEST - The AC side of the meter has two test ranges. If you are testing for voltages between 0 and 200V, you would set your meter to 200. If you are testing for voltages above 200V and up to 600V, you would set your meter to 600V. Since we will be testing for 120V from the wall socket, we will be setting the meter to 200.
TEST 1A - CHECK WALL OUTLET -The power at the outlet should be around 120V so set the meter for 200 on the AC side of the multimeter. Then place the two probes from the multimeter into the wall outlet. If you see a reading of between 120V and 130V, your wall outlet is good and you have successfully passed Step 1. Jump to Test 2A - Check Power Supply.
TEST 1B - If you see 0V on your multimeter, check the following: Circuit Breaker may have tripped; the GFCI at your outlet has to be reset; or your outlet is bad and needs to be replaced.
TEST 2C - If the reading on the meter is OV, Check for a break in the electrical wiring of the cord. Set the meter for a continuity check. PULL THE POWER CORD OUT OF THE WALL OUTLET. Place one probe in one of the holes in the female end of the power cord. Place the other probe on one of the leads on the other end of the cord that plugs into the wall outlet. If it reads 0V, move the probe to the other lead of the wall plug. There are two wires in the cord for hot and neutral. You want to make sure you are testing the ends of the same wire for continuity. Move the probes to the ends of the other wire and test it for continuity, If you don't have continuity on both wires, the cord is bad and needs to be replaced.
TEST 3E - To retest the voltage coming out of the Power Supply first TURN ON THE POWER. Then place the meter probes on the two raw wires. Be careful not to touch the probes across the wires or you will short them out. If you get 29V DC on the raw wire and you saw 0V DC when you tested the Amphenol Plug in Test 3B, you will need to run a continuity test on the plug itself. If you get 0V DC on the raw wire, you will have to test the fuse inside the Power Supply for continuity. Go to Test 4.
TEST 4- CHECK POWER SUPPLY FUSE - If you have an older style Power Supply, it will have a fuse inside that can be checked for continuity to see if it failed. The older style Power Supplies have screws in the bottom plate that can be removed for access to the fuse. If the continuity check on the fuse is negative, replace the fuse. If the fuse tests positive, the Power supply has an internal problem and you will have to replace the Power Supply. If your Power Supply is newer (without screws), it does not have a fuse and you will have to replace the Power Supply.
TEST 5D - Set the meter to 200 DC and check that the Dolphin Cable is attached to the Power Supply. TURN ON THE POWER SUPPLY. Then place the meter probes into the plug on the motor end of the Cable. If the meter shows 29V, you are getting power to the motor. If the Pool Cleaner does not respond, your motor is bad. At this point, if the Cleaner is not still under warranty, it is usually cheaper to buy a new cleaner than sending the cleaner out for a motor replacement. If the meter shows 0V DC go to Test 6A. There is something wrong with the Cable.
TEST 6A - CHECK THE DOLPHIN CABLE - If you have 29V DC coming out of the Power Supply into the Cable (See Step 3B) and 0V DC at the motor end of the Cable, you will want to run a continuity check on each wire in the Cable to verify that the Cable is broken and needs to be replaced.Remember to unplug the Cable at the Power Supply end. If the continuity checks are successful, check that you are getting a good connection at the end of the plug on the Power Cable and that all of the pins are in the Power Supply plug.
REASSEMBLY THE CLEANER - Plug the Cable back into the motor and secure it with the white Cable Retainer Plug. Don't over tighten. Reattach the Dolphin Cover and Impeller Cover. Reattach the Cable to the Power supply.
PRECAUTION 1 - During the operation of your cleaner, Make sure that your pool is free of toys or small objects that can get lodged in your cleaner and burn up the motor.
PRECAUTION 2 - When your cleaner is not in use, pull it out of the pool and keep it unplugged to avoid lightning and power surges.
