After thoroughly cleaning, including removing impellor, water flow all but stops after several hours and then the pump shuts down completely.

It sounds like your Jura Ena 9 may have a clog or blockage in the water lines or pump, which is causing the water to not flow properly and potentially causing a leak. Here are a few troubleshooting steps you can try:

1. Clean the coffee machine: Try cleaning the machine thoroughly, including descaling it to remove any mineral buildup that may be causing a clog in the water lines.
2. Check the water tank: Make sure the water tank is full and properly seated in the machine, as this can cause issues with water flow.
3. Check the hoses and connectors: Check the hoses and connectors for any leaks, blockages, or damage that may be preventing the water from flowing properly.
4. Check the pump: Check the pump to make sure it is functioning properly. A faulty pump may be causing the water to not flow properly and could also cause a leak.

If none of these steps solve the issue, it may be time to contact a professional for repair or replacement of the machine.

If the water pressure coming out of the steam/hot water arm is fine, then the issue is likely with the brew unit or the grinder. Here are a few things you can check:

1. Clean the brew unit: A dirty or clogged brew unit can slow down the flow of water. Remove the brew unit and clean it thoroughly, making sure to remove any coffee residue or buildup.
2. Check the grinder: A dull or clogged grinder can also slow down the flow of water. Make sure the grinder is set to the appropriate setting for your coffee beans and check that the grinder is not clogged.
3. Check the water flow meter: The water flow meter measures the amount of water flowing through the machine. If it is clogged or damaged, it can affect the flow of water. Try cleaning the water flow meter with a soft-bristled brush and see if that helps.
4. Check the water filter: If your machine has a water filter, it may be clogged and affecting the flow of water. Replace the filter if necessary.

If none of these solutions help, it may be a more serious issue and you may need to bring your machine to a professional for repair.

That normally signifies a leak. Under the machine there is a plastic pan with a sensor in it. However Bosch have a different idea.

What about the brushes in the motor

try removing spray spinner and clean out holes the spray heads get blocked and stop water flow, or you may be able to remove spray nozzles and clean out , i had this several times in the past also make sure the base drain filter is clean some times the small holes in the filter get smaller and smaller reducing water flow
hope this is of some help good luck

FIRST - remove plug from wall, then open lid and remove the rubber bungs that the front of the lid sits on, under them is 2 screws, remove them. Lift the complete upper plastic portion and rotate back against the wall. Remove the screw from inside the agitator and remove the agitator completly. Remove the bowl top cover by unclipping it from around the outer edge all the way round, note the spring position for refitting, lift out the bowl top cover and set aside. Remove bowl, can be tricky but it should lift right out. With the bowl removed, remove the large phillips screw from the plastic cover over the pump, with the screw removed, the pump cover will pull out (up) and the pump can be cleaned out.
Make sure that you clean out the channels that the water flows through around the pump impellor. refit the pump cover, ensure the rubber ring is in correct position, and secure with the screw. Reassemble in reverse order.

Test the pump for operation before doing a full load.

The problem is in the drain system as what error code OE stands for.The grinding noise is coming from the drain pump. Loose change, hair pins and the likes can get into the pump filter and sometimes into the pump impeller causing a grinding noise during the spin cycle because the pump works while the machine is spinning. The pump impeller may also be broken causing the grinding noise.

Disconnect power then open the filter door on the bottom left of the cabinet.


Remove the drain plug and drain the water out completely into a shallow basin or the likes. Once drained, lay a piece of towel under the filter then turn the filter knob counterclockwise and remove it. Clean the filter and reach in the pump impeller to check it if blocked or broken. If cleaning the filter does not solve the problem, you need to access the drain pump assembly and check the pump particularly the impeller thoroughly. Click on the link below for the detailed procedure in accessing the drain pump assembly.

Check where drainhose connects to waste pipe for blockage. If OK, blockage likely to be in pump impellor.
Disconnect from power.
To access pump:
Open door and remove all bottom filters. Remove all water from inside machine. In the bottom of the sump on the left hand side, you will see a star screw- remove this screw and you can remove the cover it is holding down. Under this cover you will see the drain pump impellor (white fan blade). This impellor should turn relatively easily- check for blockages (careful for broken glass!!). It can be a bit hard to reach, but you need to get your finger right around underneath impellor to ensure nothing is stuck underneath- try flicking the impellor a few times to remove any obstruction from underneath. Once clean and free from obsruction, reassemble and test

Take out all shelves and accessories that can be removed. Wash these thoroughly with a mild detergent (dish washing liquid and warm water) and rinse thoroughly. Allow them to air dry completely.
* Wipe the inside walls of the refrigerator and freezer down completely with a solution of 1 quart warm water and 2 tablespoons of baking soda. Wipe the walls completely dry.
* Leave the doors standing wide open. Use a fan to circulate air through the cabinets for several hours to completely dry the inside walls. After several hours, turn the fan off.
* Replace the shelves in the refrigerator. Place shallow trays of one of the following deodorizers on the shelves of the refrigerator and freezer:
o Baking soda
o Activated carbon (used in aquarium filters, can be obtained at a pet store)
o Cat litter
o Fresh and unused coffee grounds (this may leave a coffee smell that would dissipate after several days)
* After 24 hours, plug in the refrigerator and allow it to cool for several hours with the deodorizer still in place. Once cooled to normal operating temperature, remove the trays of deodorizer and put your food back into the refrigerator and freezer.
* Keep some cereal size bowls of a deodorizer in the freezer and refrigerator cabinets for several days

please clarify "The lower drawer does not have a similar problem." did the "but we lowered it by about 30mm as he required." make any difference? run this test: disconnect power to the unit. then find and disconnect the drain pump's wires (or connector). then apply power to the pump (I am assuming you have a 115VAC house supply) by a separate wire cord. run the pump on this cord until you see all the water pump out. if it does, then your timer is shutting down the pump too early. the water level sensor is mostly used for the other case during water fill only.
