Jura Coffee Machine No Water Coming Out? Quick fixes

If your Jura coffee machine is not dispensing water, it may be due to a blockage in the water circuit or the drain valve needs to be rebuilt. To fix this issue, replace the o-rings and regreasing the parts. You should descale the machine and clean the brew group thoroughly.

Common Causes Of No Water Coming Out

If you own a Jura coffee machine and are having issues with no water coming out, there can be several reasons behind this frustrating problem.

Water Tank Issues

One of the common causes of no water coming out of your Jura coffee machine is water tank issues. If the water tank is not properly inserted or if there is insufficient water in the tank, it can lead to a lack of water flow. Ensure that the water tank is securely positioned and contains an adequate amount of water.

Additionally, check for any clogs or blockages in the water tank’s inlet and outlet ports. Clearing any obstructions can restore normal water flow.

Clogged Water Line

A clogged water line is another potential culprit behind the lack of water flow in your Jura coffee machine. Over time, mineral build-up and debris can accumulate in the water line, obstructing the passage of water. To address this issue, you can try descaling the machine with a descaling solution recommended by Jura.

Descaling helps remove any deposits and restore the flow of water through the line. Regular descaling maintenance will prevent future clogs and ensure the optimal performance of your coffee machine.

Malfunctioning Water Pump

A malfunctioning water pump is another significant cause of no water coming out of your Jura coffee machine. The water pump is responsible for creating the necessary pressure to push water through the coffee machine’s internal system. If the water pump is faulty or damaged, it can result in no water flow.

To determine if the water pump is the issue, try filling the water tank to its maximum level and initiating a brewing cycle. If you hear the sound of the water pump working but still no water flow, it may be a sign that the pump needs to be replaced or repaired by a professional technician.

Check Water Tank

One of the first steps in troubleshooting a Jura coffee machine that has no water coming out is to check the water tank. Ensure the water tank is properly filled and seated in its designated position. Sometimes, the machine may not dispense water if the water tank is empty or not properly installed.

Clean Water Line

If the water tank is properly filled and installed, the next step is to check for any clogs or blockages in the water line. Over time, mineral deposits or coffee grounds can accumulate in the water line, causing a restriction in water flow. To clean the water line, follow these steps:

  1. Turn off the coffee machine and unplug it from the power source.
  2. Remove the water tank and empty any remaining water.
  3. Inspect the water line for any visible clogs or debris.
  4. If you notice any blockages, use a small brush or pipe cleaner to gently remove them.
  5. Once the water line is free from obstructions, reassemble the coffee machine and fill the water tank with fresh water.

Test Water Pump

If the water tank is filled, and properly installed, and the water line is free from blockages, the issue may lie with the water pump. The water pump is responsible for pumping water from the tank to the brewing mechanism. To test the water pump, follow these steps:

  1. Ensure the coffee machine is turned off and unplugged.
  2. Remove the water tank and empty any remaining water.
  3. Fill the water tank with water.
  4. Place a cup or container under the coffee machine’s spout.
  5. Turn on the coffee machine and initiate a brewing cycle.
  6. Listen for the sound of the water pump running and observe if water is being pumped into the cup or container.
  7. If you do not hear the water pump running or no water is being dispensed, there may be an issue with the water pump that requires professional repair or replacement.

You can determine the cause of your Jura coffee machine not dispensing water. Remember to always refer to the manufacturer’s manual for specific instructions related to your particular model. If the issue persists after performing these steps, contacting a certified Jura service technician is recommended for further assistance.
