, an electrical testing device that may be purchased for about 25 dollars and is invaluable around the home. With the exception of learning several easy diagnostic tests performed with a multimeter, Aquabot troubleshooting does not require any special mechanical skill.
AQUABOT IS DEAD IN THE WATERIf BOTH pump and motor are not working, (Pool cleaner is not pumping water or moving) then the problem is most likely electrical Troubleshoot the power supply 1) Reset your GFI outlet and test the outlet for power with a multimeter on the Vac 200 setting or plug a small appliance into the outlet.
2) Press the reset (if equipped) on the Power Transformer and check the fuse. Some transformers have a reset switch that must be pushed every time the machine is started. 3) Check for voltage at the Power Transformer with a multimeter set to Vac 200. Replace the transformer if no voltage is detected. Troubleshooting the Aquabot transformer: case open and UNPLUGGED. I say again, DO NOT PLUG IN the transformer with the case removed. NEVER do a continuity check with the power on. a)Perform a continuity check on the reset button by holding a probe on each terminal and holding in the reset. Continuity should be there when the button is pressed. If not, replace the reset switch b)Perform a continuity check on the fuse holder. c)Perform a continuity check of the on/off switch. If the transformer is OK, on to step 4.

replace or repair the cord.
Check the cord plug end for broken contacts. Replace the plug if needed. May be checked with a continuity test on the multimeter. 5) BE SURE THE PLUG IS IN ALL THE WAY! PUMP IS WORKING, POOL CLEANER WILL NOT MOVE. 1) Look for a broken or loose slipping drive belt. 2) Be sure the sideplate bushing that holds the drive shaft is intact. 3) The drive shaft has a plastic coated end that inserts into the bushing. If the plastic is gone, replace the drive shaft assembly
2) With the robot submerged, check to see if the drive gear is turning. If YES,
replace the belts.
If NO, check that the pin pressed into the axle to turn the drive gear is still there. SEE BELOW PHOTOS.


As a LAST resort do number 3 3) Remove the robot from the water and lay upside down. Turn on the robot for a maximum of ONE minute. Turn a wheel a little in each direction to unbind the motor. If this does not work,
replace the motor.
ROBOT MOVES, WATER PUMP IS NOT WORKING. 1) Check impeller for debris such as hair, weeds or leaves. 2) Operate the robot without the filter bag, if the pump works ok, get a new bag or clean the one you have. 3) Troubleshoot your cable. Check for broken wires between the pump and motor. Use a continuity test out of water. Disconnect the pump to check the wires. If a broken wire is found, fix it. Otherwise,
replace the pump.
MOST COMMON AQUABOT TROUBLESHOOTING PROBLEMS 1) Power cord has a broken wire between motor and handle clamp. 2) Broken or loose drive belt(s). 3) Plug end is worn or broken. 4) On older Aquabots, water in the terminal well corrodes the wires on both the cord and pump causing breakage. NEVER buy a new pump BEFORE inspecting the wire ends on the old pump for breakage Test all wires with a continuity test. It is easy to do and must be done with the robot and transformer UNplugged.
