The cold pressure is by the book at 1.5bar What aboyt the differential valve switch?? I assume this is the feedback to tell the system that the pump is working and that the water is flowing through the circuit. Is this the case??

ok, the resistence is between 1.1 ohms and 2.8 when i blow very gently

just to give some more background this problem first occured after i returned from holiday. Another thing was that the system was full of air (I would say the highest rad was completely full of air) However when the system lights the heating and hotwater run perfectly and the system pressure is...

Ok, no gas discussion With regard to the APS there is no resistenc value, it goes from O/C to C/C with the most gentle air blow down the P1 port. From the sound the mechanism makes it seems quite a positive latch when you blow. Thanks again for your input Other than the APS and the...

Thanks Tony Yes i understand the/ and your position regarding the gas regs. As soon as have As soon as I have eliminated all possibilities and found this to be a gas problem I will call a registered engineer. APS does this mean air pressure sensor/switch??? If so then I have measured the...

Hi all I have a Vaillant VUW 242 E that suffers from intermittent ignition. I have checked the following and unfortunately bought and fitted a new control pcb with no success. If anyone can help then I would be very grateful. I have checked the operation of the air flow switch. Also...
