Valliant turbo max 824e

Been to have a look
All the electric dead tests and polarity ok
System pressure 1.5 bar ok
At first the boiler fired up for a few minutes, then lock out.
After then would not fire up, sparking ok.
Inlet pressure ok, nothing on bp as not igniting.
Looked in the manual says f28 could be a number!
Any help would be appreciated. Thanks.
