Re: Neff S5456X3GB/24 Dishwasher Side panel leaks.
After chewing the gum to stick on the hole it gave me time to contemplate the situation.
I scratched up the surface with some emery paper to give a better key then used some thin plastic sheet similar to a plastic motor cover and stuck it in place with Fernox LSX.
LSX is great stuff, it sticks to wet surfaces like the proverbial to a blanket, remains flexible and will withstand freezing/boiling temperatures.
Now all I have to do is keep my fingers crossed.
Thanks for the suggestions.
