Baxi Bermuda 50/6 Lockout Problem

[Kleyshay]

Baxi Bermuda 50/6 causing me a problem

When calling for heat the boiler just goes straight to lockout with a solid red light at front on PCB and an orange light flashing twice at rear

19 mBar at the gas valve

Pump starts and works fine

1.6k Ohms and 3.8k Ohms across the gas valve

12k Ohms at 22 degrees across the sensor

Potentiometer 0 - 8k Ohms

All appear to be approximately corresponding with MI's

Replaced the PCB - no change

Replaced gas valve - no change

Replaced potentiometer - no change

Now I am stumped - So would appreciate any of your experience, knowledge or suggestions of what else I could try / test

Edit: GSR but not sure where to submit my details
