Troubleshoot lack of water flow from Quick Mill Pathfinder.

There Is No Water Flow at All

If water isn’t flowing from your Quick Mill Pathfinder, there may be a problem with the pump. Refer to the instructions below to determine if there is an issue with the pump in your machine.

  • Lift the lever. Can you hear the pump?
    • No. If the pump does not come on, manually use something to push in the switch behind the brew lever. Can you hear the pump now?
      • Yes. Adjust the microswitch behind the lever so it protrudes more, and the lever can reach it when it’s pressing down on it. 
    • Yes. Please refer to this machine's "How to Resolve No Water Flow at All From the Group" article.
      • Yes. The water lines coming off the valve under the tank should be looked at to make sure they are not kinked shut. If the water line is kinked shut, no water will come through to the pump, or be able to be forced through via priming.
        • If the water lines are fine, you can remove the waterline coming off of the pump and try running the pump to see if water comes through. If it does not, this means either the pump or the pump motor is faulty or seized. If water does come through, then this could be a sign of a bad solenoid or a blockage in the hydraulic system.

Note: Although the machine featured in the video below is the Profitec Pro 700, the Pathfinder is similar enough that the process described will work for both machines.


How to Change your Machine's Water Source

  • Lift the lever. Can you hear the sound of the pump?
    • Yes. Open the hot water valve. Does the pump refill the boiler?
    • Yes.
      • Remove the nut at the top of the group head and check the valve. It is sometimes called a mushroom valve or jet. Inspect this for any scale or mineral deposits. Clean it really well. Hold it up to a window or a light to make sure that the hole is clear of any scale or minerals. The top of the group head when removed is one piece and to gain access to the jet and the screen the two pieces have to be separated, inside the cap is where the jet and the screen sit. If no improvement, move on to the next step.
      • While you have this out, check and see if water is sitting in the group head. This would indicate that water is at least making it out of the brew boiler and into the group head.
      • Remove the shower screen. Hold it up to a light, and see if all of the holes are clear. Soak the screen in Cafiza, or purchase a new screen and replace it.
      • With the screen removed, remove the jet breaker behind it. This will be flat and can be removed with a flathead, or it will have a bolt and will require a 19mm wrench to remove. This should be inspected for any build up that will block it off.
      • If neither of the above solutions have fully restored the water flow to the group, try doing a full group head teardown.
    • No. Is the back of the lever pressing on the microswitch?
      • No. Press it manually. Is the pump coming on now?
        • Yes. Adjust the microswitch so that it sticks out of the front further, so when lifting the lever, it can reach this button, and press down on it.
        • No. Remove the housing and look at the microswitch, inspect the wires to make sure they are not disconnected or damaged. Test continuity on the switch. Is there continuity?
          • Yes. It’s possible its a bad pump
            • Test the pump for continuity.
            • Make sure there is voltage going to the pump.
          • No. Replace the microswitch.
