Dolphin MTC5 shuts offs ~ 5 seconds after power on.

[gazerbeam]

I have a 10 yr old Dolphin MTC5. Worked fine for years but just this week it shuts down about 5 seconds after power on. When press the power button the lights flash, then the 3 blue lights flash several times, then power shuts off.

I can't find any troubleshooting guide that could indicate if these lights are an error code. Is there such? Or any other suggestions to potential issues?

Have you check the impeller for any debris or binding? Those symptoms usually indicate an issue with one of the motors.

Also, you can run the cleaner for short periods out of the water, elevated above the treads so it doesn't move, so you can hear the motor and bearings. But first make sure there is no debris stuck in the impeller.

I've just removed and cleaned the filters.
This will require some disassembly, yes?
