I have a Neff hob with four jets, one of which is blocked and receives no apparent gas flow


Take the burner and flame spreader off of the affected ring.

Look in and you'll see a nut with a tiny hole in it.

Use a thin needle to clear the hole.

Be careful not to enlarge the hole, just clean it out.


Refit the flame spreader and burner cap.


Try the hob again.


If still no gas it would suggest the gas valve for that ring is the cause of the problem.


Hope this helps

Let me know how it goes or if you need more help

I have done this. The spark bounces off the aluminium ring ok - quite strong but no sound of gas.


OK, you didn't say you'd tried cleaning the jet.

However, as you have, it narrows the fault down to the valve that controls the gas to that ring.


I can't advise on how to change this valve, for legal reasons.


I can only advise that you have a Gas Safe Registered engineer carry out the repair.

This last advice has produced a bit of progress - the ring is now lighting after clearing with needle but the gas pressure is very low, not enough to anything serious with. Is there a way of further cleaning out the jet please?


I'm really sorry but the law does prevent me advising if you have to break into a gas line.


The problem lies with the jet.

Clean the jet out.



Customer: replied 6 years ago.
Can you suggest anything more I can do to clean the jet out - this seems to be the key - an aerosol or similar?


No Aerosol.

Just clear the hole in the jet.


You are able to buy replacement jets.

They screw in.



Customer: replied 6 years ago.
Ok - we're really getting somewhere now thanks. Should I be able to unscrew the existing jet for now, take it out, clean it, and then replace it? I could then buy a new jet this weekend.


Sorry, I really can't advise on this part.


The jet needs cleaning.

How you clean it is down to you.


I can't advise you on how to repair your gas appliance if it involves breaking a gas connection.


You are nearly there though.

A socket would be handy.

Good luck with it.


Customer: replied 6 years ago.
Ok thanks. You've been very helpful - I'll sign the case off as complete now.


Good luck with it.



Customer: replied 6 years ago.
Can you tell me how I do sign off and pay - I can't find 'ACCEPT'


Sorry, I'll send this as an answer, it will allow you access to the Accept button.


Many thanks.

Good luck with the repair.
