how can i fix my domi compact f 24 b?

if you followed the timer diagram incorrectly you may have cut /swapped a wire from x6 instead of the scoth block on the front.it's a bit misleading but f37 is low pressure and the diagram leads you to connect onto the terminals in x6

Chris,
I'm having the exact same problem.
Andi we did have it installed by professional / registered installer.
- Hot water works fine, fires up beautifully and is nice and hot.
- Now the CH only fires up for a few seconds at a time, makes a few water gurgling sounds then shuts off and usually faults F37, which as we take it low pressure.

Instinctively we think that trapped air in the system is to blame but cannot for the life of us expell it. Pump has been bled and all the rads.

- Clock for CH is switched to constant. And it only fires upfor a few seconds after the hot water has been run.

are you a registered gas installer then? cos i would of thought if you were, after installing your gas appliance, you'd know how to rectify any problems
