Posted Wed Feb 5, 2014, 7:35pm Subject: Wega mininova water level light stays on.
I just bought a wega mininova. I knew it needed fixing. Now, I am just lOoking at what is wrong. When I turn the machine on, the light for the water level stays on, indicating that the tank should be filled ( but the tank is already full. ) I do think it is the board but just would like some advice before I go and buy a new board. Board is Giemme MFC2SN 230 v

I don't know your machine. But the following should apply.
Make sure you are using plain water. Filtered and softened is ok. But distilled may interfere with the water sensor.
Look below the tank for the device that detects when you are out of water. Make sure the contacts are clean. If the device is mechanical (e.g., activated by the weight of the water in the tank), make sure it is making contact when the switch closes (no oxidation or scale).
Check that wire connected to the device is not broken or disconnected.

Farid is dead on, in a machine that uses probes in the water tank, you MUST have water that can conduct electrical power. Distilled or RO water is too pure and will not conduct, you need minerals in the water both for the water level sensor AND for taste, without minerals in the water, your espresso will taste flat.
If your tank is on some sort of weighing device, make sure the tank can move freely and that the switch operates correctly, these two problems cover the vast majority of water tank issues.
