Troubleshooting-Gaggia-Semi-Tank-No-Flow

No Flow At All

If the machine is not outputting any water follow the instructions below. Once flow is restored make sure to pull a full 8 oz. of water using the hot water function to ensure the machine is correctly primed.

1. Check the water tank to make sure it is filled to the max line.
2. If you are using an Intenza water filter temporarily remove it until flow is restored. Intenza filters can block the flow of water sometimes.
3. Activate the hot water function on the machine. You should hear a vibration noise coming from the machine to indicate that the pump is activated.
   1. If you can't hear anything coming from the machine then there may be a loose or disconnected wire inside of the machine. Unplug the machine and open up the top to inspect the inside for any loose or disconnected wires, particularly at the pump or the front switch panel. Firmly secure any loose wires and test flow again using the hot water function.
   2. If you hear the machine vibrating then the pump is turning on. The pump of the machine may be vapor locked, requiring a force prime of the unit. Manual priming instructions for this machine can be found here.
   3. If the pump is not making it's normal vibrating sound, but it is just humming quietly, the pump likely needs to be replaced
