Heater won’t turn on?

Hi.

I order a HP21104T (HAYHP21104T) - Hayward Heat Pro Heat Pump 110,000 BTU
I turn on the heater the outside breaker shut off.   Which shut off the heater. .    What should I look for?   Do you think it’s the breaker?

The Hayward model HP21104T requires a 50 amp breaker. Do you have it connected to a 50 amp breaker?

Yes.

It was working. It just stop

Then yes, my guess would be a bad breaker.

Thank you. Let you know what happens

That would be great. We look forward to an update.
