Actuator valve clicking sound

Hi All,

I have a combi gas boiler Triangular Tube PE110 and it seems the actuator valve is making a loud clicking noise as in this video:

The heat and hot water seem to be working, but the noise is very loud. I wonder if we should replace the actuator valve which seems to be easy enough. The replacement part is psrkit57.

Please let me know what you think about the sound.

Thank you.

    take the cover off, see what is going on. It sounds like a gear slipping inside. Usually they open and a switch cuts power to the motor.

    Or some versions just stall the motor when it opens. But the gears need to stay engaged.

    Thank you. I replaced the actuator valve and it fixed the problem (no more noise now).
