Take the tiny screws of there are loads down right hand side then release screws on hob once you can lift hob plates up. Undo the covers on back of timer clock control . Make sure you un plug from mains . Take the neutral of back of timer clock. This will allow your oven to auto ignite again

Hi yes it could be that if it only just done this leave it off you can still use the top the heat while cooking should dry it out.

I'll give this a go! With a cooker like this, you depress and then turn the control knob, press the ignition button and continue to depress the control knob for a few seconds. This is because a device called a thermocouple is heated by the flame and you have to continue to depress the control knob so that sufficient gas flows to heat up the thermocouple. If the thermocouple does not get hot or stay hot then the gas valve is automatically closed - stopping the gas. The thermocouple is a 'flame failure' safety device. If the gas gets cut off then the flame goes out and the thermocouple goes cold switching off the gas valve automatically. However, you are having to try and manually keep the gas going for a good five minutes. I would think that there is either a problem with the thermocouple or the gas control valve!

Some have a AAA battery under the button - replace this, others use mains to create the spark, ensure you have the ignition wired up

Replace the oven thermocouple.

The knob won't have any effect on the flame size.  The knob controls temperature.  If you're referring to the pilot light staying on and then the main flame not going on...that's another problem.  If the main flame will not go on, the assembly that controls the main flame is likely defective.  If the unit has a thermocouple, you might change it out first.  Sometimes, that's all that is needed and they're cheap.

problem with hob is probably water ingress in area of ignition unit - will probably cure itself oven is a completely separate unit from hob. problem with it is that you have to re-set the clock - you have it on automatic. after power outage, oven clock always has to be reset
