Goblin D26 Teasmade
Hello, anyone have a wiring plan for one of these. I've been given one by the wife of a old pal who sadly passed away. The light works, the clock works, the kettle works, but I can't get the buzzer going. The kettle will start at the alarm time and boil, but not switch off. What's the correct way to set the alarm etc? a copy of a manual anyone? thanks guys :thumbsup:

Re: Goblin D26 Teasmade
The kettle when boiling uses steam pressure to expel most of the boiling water into the tea pot, the reduced weight of the now nearly empty kettle then opens a switch to turn off the kettle.
If the kettle is boiled without the lid in place, then the water wont be expelled into the tea pot and the kettle will carry on boiling until enough water has boiled away to reduce the weight. |

Re: Goblin D26 Teasmade
First the kettle was boiled with the lid on the other link is for a different model...
the kettle is in need of a good descaling... would that alter the weight issue? when i dial the alarm round it makes a slight click and the kettle starts. is there away to clean the contact on the alarm buzzer? i thought it might be dirty etc :shrug: |
Re: Goblin D26 Teasmade
All Teasmades from the 1930s to the 1970s are pretty similar in how they operate. The D26 is the "bring your own teapot" variant; which is even simpler, as it does not include the "teapot present" switch
The base on which the kettle sits actuates a changeover switch. When the kettle is full of water, the base rocks down and the changeover switch sends power from the timer switched contacts (connected to the moving contact) to the kettle heating element. When most of tbe water has been transferred (by steam pressure) to the teapot, the base rocks up and the switch contact changes over. Now power from the timer switched contacts is diverted to the buzzer and lamp. If the kettle is placed on its base with no water in it, then the timer contacts will already be connected to the buzzer as soon as the hour hand of the clock reaches the set time. (Note that the set time is supposed to be when the kettle has finished boiling, so the switch contacts actually close several minutes before the hour hand reaches the indicated time.) You should be able to do all the tests you need with a simple multimeter and the Teasmade not connected fo the mains. The symptom of "no alarm / kettle never switches off" sounds as though the changeover switch is stuck in the .""down" / "kettle full" position. |
Re: Goblin D26 Teasmade
The buzzer in these Teasmades has no contacts. It's just a coil of wire connected to the mains (when the buzzer is in operation) with a magnetic armature 'flap' at one end. The flap is attracted when current flows through the coil, it springs back when there is no current. As the mains is AC, the flap vibrates 100 times a second (it's attracted on every _half_ cycle of the mains) thus buzzing. It's possible the coil has failed but unlikely.
I agree with Julie that the problem is most likely related to the kettle-full switch/mechanism. You should be able to press down the platform the kettle goes on (it's hinged at one side I think) and have it spring back when you release it. Sometimes enough water is spilt from the kettle over the years to cause rusting in that area, either making it stick or rusting away the return spring that pushes the platform up again. |
Re: Goblin D26 Teasmade
many thanks for the info... will try what you have stated after i have given the kettle a good descaling thanks folks

Re: Goblin D26 Teasmade
well the 2 springs and switches were very rusty and broke when they were touched. so now i have removed the clock and lamp part and will now use it as a light with a alarm clock.
