Customer Question

I have a Triangle Tube Prestige Solo 250. We were away and came home to a Error (Hard Lockout) Mode error code of E 04. Manual says it is "Power supply lost after lockout occurred". Manual says to perform manual reset by pushing RESET button.
Pushing the RESET button does not do anything.
Turning the power on and off at the power button and at the breaker panel will have the unit kick on for 1/2 second and then go back to E 04.
There were storms while we were gone and the power did fluctuate on and off.
What can I try to get this to reset?

Hello, the description is that of a bad board. There is no basic reset...unfortunately this will require a service call or board.
