I have a problem with my autofill on my gaggia te manual machine the autofill turns on fine when its supposed to but as the water starts to slosh about and hit the probe the autofill cuts in and out until im assuming the water is steady over the probe then it cuts out as it should. Is there anything i can do to adjust the sensitivity? I opened up the gicar autofill box and found a little thing with something i could change with a screwdriver (looked like a variable resistor) So i changed that to both extremes and it made no difference. Any ideas people?

The autofill box is defective and will have to be replaced. It is cutting out rhythmically which it will do even if you disconnect the wire from the probe. New boxes will run you $100 to $200 depending how many levels of markup you go through. If you look at the contacts on the relay inside you will likely find them burned.

You sound dead right, i havent actually tried it with the probe unplugged but i will give that a go. Is there anywhere i can buy the relay and solder it on myself? Or are they gicar parts which you cant find easily?

I can confirm when the probe is uplugged the boiler fills as it should until the end is earthed on anything in the machine this makes me think there is nothing wrong with the relay. Its the way the water splashes on and off of the probe, its too sensitive, or i have read that some gicars have a time delay so it fills 5 seconds or so after it hits the probe although i dont think this gicar features that as it has no integrated circuit chips on the board.
