Went to make a brew this morning sat in the T6 overlooking Ullswater - the gas ring wouldn't light. The interior Propex contents gauge is showing 3 green LED lights and no red fault codes. If you press the interior on/off button you can hear the exterior solenoid isolation valve clicking and I presume this means it is opening / closing? Checked the rear BBQ point with an open ended hose and no gas here either. Any body - any suggestions?
