Removing the auto-off timer from my coffee machine (infosec.pub)

My drip maker shuts off. This is very frustrating, since no human should attempt the consumption of six cups of coffee within thirty minutes.

I'd like to get rid of this timer, but I can't see anything obvious on the board. Is it most likely to be in that little processor at the top left of the coated side?

lmao some of these replies are exactly the sort of thing you'd expect from reddit in like, 2011. For reference, even mildly scalded coffee tastes better than that instant shite, and I'm not drinking ut for taste.

This is probably a bad idea, because the timer relay circuit probably has some additional safety features in it such as temperature limits, along with the device never being designed to run indefinitely.

If I had to guess, the heating element is controlled by the relay (big black cube). I would either bypass the output or bypass the input signal. The relay pinout can be easily found online on sites like this.

Bridging brown and red or whatever colours not blue and white are will bypass the board entirely.

If that is the only pcb in the device op should be able to just put any (mains capable!) switch there to just toggle the entire device on/off

It almost certainly is designed to run indefinitely, this exact same coffee maker has been in production since the nineties or so. the only addition is the timer circuit, which is very clearly a much later addition, as the supporting structure is markedly different tk the rest of the device.

Anyway, a 240v switch is in order, I think. Fortunately we still have Farnell here in the UK, I shouldn't like to pay international shipping fees for a single switch from china.
