I have a stand alone Zanussi ZCE7551X oven with a euroKera ceramic hob. There is a foam/rubber seal that goes around the edge of the hob, to ‘seal’ it flush into the top of the oven casing, and also I suppose stops liquid from going beneath the hob. The seal has started to separate from the surround, and the hob is lifting up. There is currently about a 5mm or so gap between the hob and surface of the oven. It has only started at the back and partially one edge, but if it continues, the hob will just be sitting loose on top of the oven, and not be sealed in. This foam/rubber seal is not a spare part. Has this happened anyone else, and what have you used if it has. I was looking at car sealing mastics, silicones, gasket repair glues ,and hob sealant etc.. But I didn’t want to take a guess at what might work before asking around! Hob sealant seems like an obvious choice but that seems to be to seal a hob into a hole in a worktop, and I’m not sure if it would be the best option in this case.. Thanks.

a few pictures would give us a better idea what your problem is and where

Hope this helps to see the lifting of the hob..
Re: Stand alone oven & hob foam/rubber sealant liting away
Its this rubbery seal ( the line nearest the glass) that is pulling away from the plastic surround on top of the oven..
Re: Stand alone oven & hob foam/rubber sealant liting away
see what you mean. This cooker is over 10 years old and the ceramic top would be supplied as a complete unit but its obsolete
All you can try is to source some high temperature silicone sealant and fill it in. that’s similar to what would have been used in manufacture

this one will go up to 230 degrees C but I would check colour
it does worry me a bit is seem to be lifting as I would expect it to stay put and the seal just rot. It may need a closer look to see if anything else inside is out of place. It may just be the rings as they have springs to hold them close to the glass in which case to glues it you will either have to remove it completely or carefully weight it while it sets

Re: Stand alone oven & hob foam/rubber sealant liting away
Thanks.. I couldn’t understand why it seemed so springy! And yes, It would need a reasonable weight on it , whilst whatever sealant I use sets..
Re: Stand alone oven & hob foam/rubber sealant liting away
i bought a tube of this stuff. Technicqll Elastic Black High Temperature Silicone. I had bought their shoe repair glue and it was brilliant, and all their products get good recommendations. Here’s hoping.
Re: Stand alone oven & hob foam/rubber sealant liting away
Well that didn’t work! The silicone made a seal of sorts, but it couldn’t resist against the springiness , and it just gradually pulled away again..Is there as way to combat the spring ?? It seems excessively strong….
Re: Stand alone oven & hob foam/rubber sealant liting away
1 did you leave it to set long enough
2 was it clean enough, any grease and it wont stick
think what I would do is remove the top then you can add some more sealant underneath. You will probably have to take the rings off but leave the wires on so you wont have connection problems as it looks like rings are attached to the top someway . You also need to make sure the silicone you are using sets harder, I think there are different types that set to varying degrees of hardness (less rubbery ) but don’t know a supplier

Hi joh
Where in the country are you ?

Re: Stand alone oven & hob foam/rubber sealant liting away
I’m in Belfast..! My main fear is that, the hob will lift off entirely, and just be loosely sitting on the oven top and be unusable. I have looked online to try and understand the layout underneath and how it is connected but I haven’t found anything.. The big problem is the strength of the springs. I had to put 7x 2 litre bottle of water on the hob to hold it down, and left it a few hours after using heatproof silicone. The hob just lifted up as soon as the water was lifted off…
Re: Stand alone oven & hob foam/rubber sealant liting away
The silicone would work if the pressure on the hob wasn’t so great. I really need to find a very strong adhesive and sealer in one…
Re: Stand alone oven & hob foam/rubber sealant liting away
I think a few hours is not enough I would have said 24 hours at least. check the tube, its normally a couple of hours to skin over but takes a lot longer to set through
let see what bryan has in mind

Re: Stand alone oven & hob foam/rubber sealant liting away
Im going to try what i have again – only leave it longer. Its a heatproof silicone gasket sealant i used. It’s main function is not as an adhesive, and as there is not a lot of surface area to grab onto i think the silicone alone is unable to withstand the upward pressure. A black grab adhesive would possibly work. I have seen one at screwfix for a tenner.
