Why doesn’t my Dolce Gusto flow anymore?
The problem of a Dolce Gusto that does not flow can be caused by the water circuit preventing the water from circulating, or by the coffee itself causing the water to flow without coffee or blocking the water flow.
Why doesn’t the water in the Dolce Gusto flow?
If the nozzle of your coffee maker is clogged , the water will not come out of the Dolce Gusto. To clean it, disassemble the coffee maker:
- Remove the tank and any easily removable parts.
- In the middle of the coffee maker, in the area of the tank, there is a maintenance spring, similar to a small needle.
- At the level of the capsule holder, at the top, there is the nozzle that pierces the capsule: clean it with the spring.
My Dolce Gusto no longer flows: check the water tank
Remove the tank from the machine, fill it with water and press the valve underneath. If water is coming out, the tank is not the cause of the problem with the Dolce Gusto not flowing.
My Dolce Gusto no longer flows: restarting the water pump of the Dolce Gusto
If air has entered the water circuit of the coffee maker, the water pump may have become defective: it no longer produces sufficient pressure. This can be the result of an air leak in the circuit or simply after having operated the coffee maker without water in the tank.
Normally the pump primes itself, here is the procedure to prime the Dolce Gusto pump:
- fill the water tank
- put the tank in its place
- remove the tank from its location
- put the tank back in place…
- repeat the operation about fifty times.
During the operation, air bubbles should escape and rise in the tank.
Turn the Dolce Gusto back on and test it by pressing the hot or cold water button.
If it still doesn’t work, wait a few hours (ideally overnight). The air will slowly escape and the Dolce Gusto pump will restart itself.

Test the hot and cold water selector of the Dolce Gusto
To solve a Dolce Gusto hot/cold water selector problem, you must test it:
- Start by unplugging the coffee maker and then disassemble the front of the machine.

- Use a multimeter to perform a continuity test.
- Place the multimeter tips on the selector terminals.
- If the unit does not display anything and does not beep, the selector switch is not to blame.
- If the multimeter displays zero and beeps, the selector is short-circuited, the lever must be moved in one direction and then in the other.
- Re-measure, if you still can’t find zero or don’t have a beep, the switch is at fault and needs to be changed for a new one.
