looking for some help please. i have a vaillant ecotec plus 624 boiler. I recently had to drain the system down in order to change a radiator. The boiler is only a year old and worked fine until that point. I have filled the rad system back up again and bled everything but the heating keeps turning off with a message that says water pressure too low. I refill it but in a couple of hours the pressure has dropped ahain. have double checked all the new connections that i made and none of them leak. Is there something inam missing? Thanks.

How did you drain the boiler in the first place?
 
Could have a bit of dirt in pressure sensor giving incorrect reading and you top up system which may have over pressured and opened prv. Get your installer back to have a look
