Burnham fcm 120

HI

I have a Burnham freedom 120 and last night it stopped responding to a call for heat. The thermostat is fine and the boiler work when hot water is called for. On restart the main circulator pump operates for a few seconds, so power is fine.
The mode button does not seem to work to turn on manually.
Any suggestions on troublshooting.

What is displayed when you have a call for heat and not for hot water? Press the Mode button until the screen displays PARA. Step down to parameter #3. What is displayed.
The buttons are hard to press due to the mil of plastic. Use your fingernail dead center.

Thanks for quick response
I would not have used so much force without your suggestion took the end of a wrench wiggling to get mode button to respond. It read 0--how would it change to this on its own.
I set to 3 got unit to run normal than change to default 1
seems to be working but I'll know for sure after next few cycles.

Did someone press the + key for more than 3 seconds? That will change it. BTW the - key will change the DHW.
