Bosch dishwasher not filling with water. A Bosch dishwasher needs to be filled with water in order to function efficiently. You should not let the water get close to the door latch, however.
We do understand that you might be concerned if your dishwasher isn’t filling properly because it might mean that your dishes are not washing properly.
So let’s take a look at the potential causes and try to figure out what they mean so that we can determine what we need to do next.
Bosch dishwasher not filling with water
There is no water in the Bosch dishwasher. In order for Bosch dishwashers to function properly, they must be filled with water.
If this doesn’t happen, there are several reasons why this isn’t happening.
Defective water inlet valve
Water enters the dishwasher through the water inlet valve.
If the water is not flowing smoothly and evenly or if it’s leaking out, you must replace the water inlet valve. Water inlet valves are not repairable, a new one must be installed.
Problems with water supply
Over time, calcium deposits build up and can clog up your dishwasher’s water line. Therefore it is commonly said that your dishwasher will not fill if this is the case.
Now that you have determined whether or not there may be a problem with the water supply to your unit, start by turning off the water to investigate where the issue may lie.
Inspect the valve for any signs of a clogged screen or another obstruction in the valve.
If you notice there is excess pressure in your plumbing system then this can cause issues with how much water gets shunted through to your dishwasher as well.
One way to avoid this from happening at all is making sure you call your local plumber who regularly services on-site if need be.
Faulty float switch
If water gets into the dishwasher and causes it to overflow, this float switch may work under and stay in an actuated position due to the force of the water that enters.
Any time there is a high-level float switch malfunction such as this one, it needs replacing.
A problem with the Hose Filter
Most Bosch dishwashers have an installed special filter inside of the hose end to prevent sediments from the water supply pipe from reaching the interior of the dishwasher.
This is intended to keep the dishwasher in optimal condition, but sometimes this filter clogs up and needs replacement. To prevent this issue in future.
Bosch recommends changing your kitchen faucet aerator every two years or so; replacing it could lead to less surprising issues like these.
Low Water Pressure
To check your water pressure, just open the tap all the way. You want to collect at least 10 liters of water over a 60 second period or so. If you do not obtain this result, please contact your plumber.
Pooling of Water
The dishwasher does not fill because the drain it uses to empty its water is blocked. The most common culprit is a large utensil or another item that was left in the drainage tube.
Open your dishwasher and locate the large-object trap in the center bottom of the appliance.
Lift out the catch and remove any large pieces obstructing the hole, then rinse afterward with warm water to clear any remnants that may have caused a blockage in the first place.
Once it has been cleaned sufficiently, replace all of the removable parts back into their correct positions before closing your appliance’s door.
If you find that your dishwasher begins draining again normally, you are free to restart your cycle without having to undo previous steps.
