Dolphin M4 will not run

by Phil
(St Louis, Mo)

This is what happens:

If the cleaner is not plugged into the power supply/controller and I turn on the controller, the on switch lights up and the three 123 lights blink for a few seconds, then just the on switch is lit.

If the cleaner is plugged in then the on switch lights up momentarily (maybe a second) and then goes off.

wrt the cleaner.

The impeller at the top turns, though will not freely spin (I would not expect it to).
The tracks will turn, again not freely (I would not expect them to).

So, it appears there is nothing jamming either the tracks or the impeller.

Other thoughts?
