Vibiemme Super Boiler Refill Not Working
First time poster here, and I have scoured through previous posts trying to find an answer but none are exactly the same issue.
My 10 year old Vibiemme Super HX has stopped autofilling, and if not for having just spent $600 on a service and full descale / scale repair, I would take it to get checked out. But before spending much more on it, I would love to see whether I can find the issue.
When the boiler level is low, nothing at all is happening. No Pump, no clicking of the solenoid just silence.
-Tested resistance on the level probe, and cleaned - can see continuity when the probe touches the boiler water, and no continuity when the water level is low or probe is pulled out. So the level probe does not seem to be the issue.
- Tested and replaced the autofill solenoid coil with a brand new one. Still not the issue (as I said, not actually hearing the click).
- I have read that sometimes it can be the Gicar controller, and have opened it up to check for any crazy obvious faults, and visually there does not seem to be an issue.
Does anyone know what the best method of testing the controller would be (to narrow it down)?
Does anyone have any other suggestions or testing I can do to narrow it down?
Everything else works fine, the machine can brew and steam when water level is sufficient.
I could replace with a new controller, but the last thing I want to do is go spend another $300 for a controller, if its not the issue.
Thanks in advance for any help
So if you pull out the probe, or disconnect it from the Gicar controller the pump won't come on?
On a couple of occasions my machine has failed to respond to the Gicar controlled touch pads. Both times I pressed the ribbon cables firmly into the Gicar and everything worked again.
If that doesn't fix it, you may want to open the controller again and trace continuity to the probe and check for swollen capacitors, dry solder joints as two of the usual suspects in circuit boards.
The probe will turn on the pump if it's not touching ground. If the probe is out of the boiler, suspended mid air, the pump should come on and remain on until the probe is grounded on something, be it the boiler, chassis or of course, water in the boiler.
That thing to the left of the resistors is a transistor.
You can test them.
Also If you have a magnifying glass, run it over the solder joints and see if any are "dry". A dry joint looks dull compared to the good ones, and will be separated from the component's protruding wire.
