Gas Hob Ignition

I have just replaced an existing electric cooker for a client. They have just called to say the gas hob ignition is not working. I haven't chnaged that, wiring was done like for like and tested. The only dufferent thing I have done is swapped the MCB from a 32A to a 20A as it was overated. The cooker is 2300 watts. They are plugged into a double fused socket. 13Aand 3A. I haven't been over to look at it yet vecause they have only just notified me. Can any of you think off hand what it might be?

Forgot to switch the socket back on behind the cooker?

Something caught the switch on the socket behind socket as you pushed cooker back?

Probably no power but  as an sparks you will find this out quickly.

I'm new to this I get the electrical side and will test with the merger but I lack the practical stuff that only comes with time. Just wondered if anyone has come up with something less obvious that I might not immediately noyice

Are you sure it actually worked before you touched it maybe they are pulling a fast one.

Welcome to the forum by the way.

You lowered rating of mcb, why ?

What was it wired in, was it 6mm², 2.5mm², has the twin socket replaced the old cooker outlet plate, is there a cooker switch with outlet on it ??

The cooker power is 2300w so 2300/230 is 10A. I have left it at 20A in case they need to add a hob in future. it was in 6mm. there is a double fused socket. seperate socket for hob ignition with a junction in the back behind the work surface. all i actually touched  was the junction box to take out the old and put in a new oven and the fuse board to put in a 20A MCB

so this is a built in oven and separate hob which is gas that are plugged into a 13 amp double socket. oven is 10 amp and 3 amp for hob ignition?

This 6.0mm² comes from where ??

Do you have a cooker switch above worktop now feeding outlets at back of oven.

I do agree the socket for the ignition has probably been knocked off when pushing oven in, but why fuse down ?
