Boilermate WH-7L won't come on after power outtage

Argh. We have a Buderus boiler with a boilermate hot water heater. Came home after a week away to find clocks blinking. Heat was on. No hot water. No display lit on the smart control. flipped the circuit breaker. Boiler fine. No joy on the boiler mate.
It has never given us any trouble. (well, except for that poor chipmunk ... ) No buzzing or humming from the smart control complained about elsewhere here.

With the boiler running fine, can we press the reset button on the front anyway? Would that reset the smart control on the boilermate--or just screw up the boiler? Or did we already "reset" the system with the circuit breaker? Tomorrow is the day b4 Thanksgiving. Can't face this holiday w/o hot water.

    At a guess -- whatever that power failure was fried something relating to the boilermate... kettle time?

    Sorry, kettle time?
    I think we had a typical brief outtage due to heavy snowfall. This has happened at least 6-10 times since installation. But hot water never affected before. Once we ran out of oil and I had to press the reset on the oil burner. Went perfectly.

    The power outage almost certainly burnt out the smart control.
    Unfortunately this is not an uncommon thing.
    It needs to be replaced.
    That control cannot be repaired.
    And IMO that control is not one that we like installing, it has a significantly higher than average failure rate, for many reasons

    There are other options when replacing that control, there is a standard dial type control that is not electronic.
    That is the best way to prevent future issues exactly like this.
    That being said it may require a separate circulator control relay.
    And again it may not, it all depends on how your system and controls are wired.

    But the quickest and simplest way is to just change out the smart control.

    Oh boy. Would we be better off replacing the boilermate with a regular electric water heater?

    As long as the tank is not leaking, just replacing the control should be fine.
    And unless you have extremely low electric rates, an indirect water heater (which is what the boilermate is) is far more efficient and output and recovery is incredibly higher.

    Thank you so much for your time. Would it hurt anything to try the boiler reset button?

    Call a service company or if is an oil fired boiler, even your oil company.
    Tell them that your boilermate smart control is burnt out.
    The replacement part is readily available at almost every supply house.
    It can be changed out fairly quickly.

    Or depending on how capable you are, you maybe able to do it yourself.

    Unfortunately not.
    It's probably a good 3 1/2 hours away from me

    Try and contact your oil company or a plumbing company
    I'm fairly certain that any of them can handle this problem and that they should be able to easily get the replacement part
