Any ideas on this issue,

This is the boiler at home and its doing my head in.

Every night about 4.30 am it makes a loud hmm then 4 loud thud noises then abruptly stops and this repeats every night.

Last night i caught the boiler doing exactly this whilst getting a drink , nothing showing on display and ironic if its in stand by mode it still does it.

Its exactly the same noise it makes when you turn the mains power on but much quieter and more subtle when i do this.

What is causing this ??

No Idea , it makes the same noises if you turn the main power on the socket to the boiler however its much more aggressive and loud through the night to the point of its like a hammer banging

Got a water meter but no shock arrestor

Treat yourself and get one, it may cure the problem, and it'll stop the dhw heat exchanger seals leaking in the future!
