The pilot light stays on, but even when there is no hot water, the boiler does not flare up to start heating the water even at Maximum level. There is normally a click when you rotate the temperature valve but it has stopped occurring when you rotate it. I have tried to switch off the pilot light and relight but still not working. can anyone help?

Thanks Ltd. I have a Drayton Digistat+ thermostat. The minimum temp is 5 degrees celsius, the maximum temp is 30 degrees celsius. The current reading on thermostat is 22 degrees, though I have set it to 25 degrees. I am still getting no joy.
