Hello and welcome to JustAnswer!
This is James, I'm an appliance repair technician with over 10 years of experience, and I'll be assisting you today.

Sorry to hear your appliance is having issues, please stand by while I find the answer for you, this is not an immediate service however I will try and respond as soon as possible.

Based on the symptoms it suggests the motor is causing the alarm and resulting in a earth leakage fault which is tripping the breaker. You will need a Nibe engineer to attend and strip down the heat exchanger to verify if the motor needs replaced.

I would contact the firm who did the install or yearly service to arrange repair.
