Boiler 5 years old pressure varies between 1 and 1.5 psi. No works done, noise just started recently. Only when hot plate required.

Not really hard water, no problems with kettle or saucepans furring up.
From the description, it sounds like air trapped in the boiler. If so, needs purging and/or a new AAV. Not a DIY job IMO. At 5YO, it's probably still under warranty. If so, call Bosch (or your installer) and they should fix it for free.
The AAVs in Worcester boilers of the same age as yours seem to be a bit troublesome.

Hello, I have just moved in to a new flat this week and have a problem with noise coming from somewhere around the top of the boiler.
It's a loud clicking/knocking sound that lasts about a minute, stops for 20-30 seconds and starts again. It seems to happen at night, starting in the evening...
