Goblin Teasmade D25, disconnected wire. - UK Vintage Radio Repair and Restoration Discussion Forum

I have a D25, works great but no buzzer. Upon inspection, I found a green wire with soldered copper end had been disconnected, but from where? any ideas?

Thanks.

There are a few green wires on the D25; here's a diagram to help, though it's not yet complete:

Probably the normally-closed contact of the kettle platform switch.

Teasmades are gloriously simple, wiring-wise.

The kettle sits on a weight-operated changeover switch. When the kettle is full of water, the switch is operated and the switched live from the clock goes to the kettle heating element. At boiling temperature, the water begins to boil; and the steam forces the liquid water out (the kettle spout is extended on the inside to dip down into the bottom of the kettle, so steam rising above the water pushes down on it; and up the spout is the only way for it to go). When the kettle drops below a certain weight, the switch is released and the switched live from the clock is diverted to the buzzer. If the kettle boiling didn't wake you, the buzzer definitely will!

The light is supplied via another changeover switch. In AUTO mode, it gets its feed from the kettle platform switch so as to come on with the buzzer. In LIGHT mode, it is switched to a steady live instead.

Attached are photos of the wiring of my mother's teasmade that I took some years ago before dismantling it. I don't know the model number, but it was bought around 1970. On my mother's model, the "green" wires are in fact Yellow/Green, and provide the earth connections.

She hasn't made tea with it for years, but uses it as an alarm clock: she is profoundly deaf, and the light that comes on when the alarm buzzer goes off, wakes her up. The fault turned out to be dried-up grease in the motor pinion gear that was causing it to jam intermittently.

Are you sure you need the buzzer! It's very loud and most people are woken up by the lamp and bubbling sounds of the boiling water.

Quite. The buzzer is horrific. I disconnected mine. I wish they'd made them with a bell.

That is an 855 which is later than the OP's D25 and the wiring is considerably different.

Both of these models do allow the buzzer to be adjusted to be quieter, incidentally.

I have just got my D25 back out of the box, given it a good clean and have it all back in working order, but as previous comments remark, the buzzer is awful.
I would be interested to know how it can be adjusted to make it quieter before I either disconnect the buzzer entirely or risk throwing the thing out the window....even my neighbours complain of the noise!
