Hi,

New to the forum, eager beginning amateur.

I am interested in creating a device that would reverse the pump motor (decorative outdoor fountain) rotation for about 5 seconds, about once per hour. The purpose would be to clear debris from the filter, which accumulates detritus and impedes water flow.

I would appreciate any suggestions or comments. Thanks for your consideration.

It would depend upon the type of motor. Shaded pole, out of luck. Single phase with start winding and start switch, possible, but not too easy. 3 phase, easy.

Not likely. AC motors generally can't be reversed unless they are designed that way.
Look for an extra wire. Maybe it has a "reverse", maybe not.

ps, also not likely that a decorative fountain has a 3 phase motor in it.

Seems an auxiliary pump of some kind for back flushing is in order. Or valving.

Even if motor is reversible, pump may not be.
