We have an HTP flash heater MC-100 that is overheating.
I've posted a 1.5 min video of the control panel as the unit cycles.

Not finding corresponding troubleshooting recommendations in the manual. Of course, if it's there, it probably reads "call a certified tech". But, we're sheltered in place a long ways from a tech.
Comments and recommendations appreciated

From the description you are not getting flow. Is something shut off, circulator broken or debris plugging the piping?
