Re: Bosch hotplate tripping RCD
Thank you, Penguin45, for your reply, but I’m having trouble interpreting it.
Three of the hotplates are three years old, and the fourth is about one year old, so none of them is very old.
Tired? I don’t understand this at all. Do hotplates get tired? Surely they either conduct or they don’t conduct, and the insulation either leaks or doesn’t leak?
Is there not some fault-finding process that a professional repairer would follow in this situation? Surely they wouldn’t just label a 3-year old hob as being old and tired, and advocate replacing the entire thing, would they?
The particular knowledge I lack is why a hotplate can heat up less then when it was new. Does it mean that its resistance has increased, so that the power dissipated is less?
BTW, the price I’ve been given for hotplates would be a total of £130 for all four, and on your own web site they’re even less than that. A new hob would be at least £150, so it’s definitely cheaper to repair it, given that one hotplate is still working.
Do you think that the switches/knobs could be at all faulty?
Regarding the pot luck with the forum, I merely asked if the absence of replies and abundance of views was normal. I guess you’re saying that it is.

Thank you, TheSpinDoctor, for your reply.
I shall move in the direction of replacing the suspect hotplate.
If I say that the two large hotplates seem to be incapable of boiling water in a saucepan within the normal limits of human patience, whilst the remaining hotplate, a small one, brings water to the boil very quickly, does that give you any confidence that there is a tangible problem?
If so, what’s the list of possible causes of such a problem?
