Dolphin Magic runs for 30 seconds

by Calin Diaconu
(Roman, Romania)

I have a Dolphin Magic which runs for around 20-30 seconds and then stops. I opened to inspect the circuit board and it looks fine. I checked the cable and the motors and they are also running ok.
When I start the power supply the traction motor starts, after a few second the suction motor start and run for 4-5 second then stops and after that also the traction motor stops. On the circuit board are two leds, on red and one green. When starting the green led blinks 7 times and after that the red led blinks once. To start again sometimes I have to wait around 30 seconds.

Dolphin runs then turns off

How do you do a pump rebuild? Should this be done by a technician?

Bad pump
by: Dom Lando

Your main pump motor is probably filled with brush dust and is pulling too much current. The circuit board is programmed to cut off power in order to prevent damage, thus turning off very quickly.

You will need to do a pump rebuild.
