Same problem as you all. Local gas repair man gave three options. !st a new bit at £10 2nd another new bit £65 or 3rd he could isolate the auto ignition, still leaving manual electric ignition ( you have to keel pressing button untill ignition ) this would also allow me to keep cooking in a power cut whereas the auto system would have shur the gas off. Opted for 3rd option, took him 20mins and charged me £20. Happy days
