Bosch washing machine does not fill with water

It can be confusing and frustrating when your Bosch washing machine stops filling with water all of a sudden. When this appliance malfunctions, it throws off your routine because you depend on it to provide clean clothes.

This problem could be caused by a number of things, from something as straightforward as a blocked hose to more intricate issues with the machine itself. It can help you detect and potentially solve the issue more quickly if you know where to begin.

This post will discuss common reasons your Bosch washing machine might not be filling with water and offer helpful advice on how to restart it.

What breakdowns caused this?

It is imperative that you address the issue as soon as possible because a Bosch machine that is empty cannot wash objects. The central water supply may have been turned off, so you should first make sure there is water in the pipes. Making sure the hatch door is securely shut is the second step, as the system won’t activate the UBL or issue the command to fill the tank if the drum isn’t locked.

We start extended diagnostics if the door and the water supply are operating properly. Water intake issues can result from a number of malfunctions, including pinched hoses and control board damage. Finding the "culprit" is not hard if you are aware of the primary "symptoms" of common malfunctions and breakdowns.

• Broken filling valve. If it was previously noticed that the powder from the cuvette is not completely washed out, then it is highly likely that the part has failed. It is easy to make sure that it is working: just plug the element into the network and supply 220V to it. A serviceable valve should close and click, and if there is no response to voltage, a replacement is necessary. We check two devices at once.
• Clogged mesh. The machine does not fill with water if the inlet filtration system is clogged. The machine will try to fill the tank for a long time and buzz characteristically. The problem is eliminated by dismantling and cleaning the mesh.
• Clogged filter. Often a dirty coarse filter prevents filling. It is necessary to clean the nozzle.

The Bosch display indicates that an excessive amount of water filling time has been recorded by the board if "F17" or "E17" appears.

• Failed pressure switch. If the level sensor is faulty, the control board cannot track the degree of filling of the tank and, for safety reasons, does not start filling with water. To confirm the breakdown, you need to remove the top cover of the machine, find the device, disconnect the connected tube, substitute a hose of a proportionate diameter and blow. A working pressure switch will “respond” with clicks, and a broken one will “keep silent”. In the second case, the part must be removed from the housing, inspected and cleaned. Probably, the nipple is clogged, and after “blowing” it will return to shape.
• Pressed inlet hose. It is possible that the rubber band is pinched and does not allow water to “pass” to the Bosch.
• Damaged pressure switch hose. During operation, it loses its tightness, wears out and lets air through, creating problems with pressure and the operation of the level sensor.
• Faulty drain pump. If the board has recorded a pump breakdown, then water will not start filling. First, you need to repair or replace the part.
• Broken board. If there are problems with the "brain", the washing machine will not work at all, and in particular, will not fill with water.

If the Bosch washing machine has a display, you should pay attention to the error code that shows if there isn’t one. You can quickly identify the "culprit" of the failure that occurred and narrow the scope of problems by decoding the combination using the factory instructions or the Internet.

A kinked hose, a clogged water inlet filter, or a door latch issue could be the cause of your Bosch washing machine’s inability to fill with water. In more severe situations, the machine’s control board or the water inlet valve may be the problem. By being aware of these possible reasons, you can identify and resolve the issue on your own, avoiding the need to hire a repair professional.

Is it worth climbing into the machine body?

Repairing a newly purchased washing machine on your own is not advised. Remember that all Bosch models come with a one-year warranty; therefore, seeking professional assistance from a service center is more dependable and less expensive. Prior to contacting a specialist, opening the case will automatically end warranty service.

Only experts at the service center perform diagnostics and repairs on washing machines that are still covered by warranties.

When the machine is not covered by the warranty, that is a different story. To avoid overpaying the master for the repair in this instance, it is preferable to attempt to resolve the issue yourself. Make sure the shut-off valve is open after verifying that the central water supply has been turned off. Next, look for damage and pinching in the inlet hose. In the event that no issues are apparent, you will need to "open" the machine and carry out a thorough diagnostic.

Start looking for a malfunction

You must plan ahead and determine the steps to take in order to get the washing machine operating again. The washing machine must first be unplugged from the power source and have the water supply valve closed. These are legally required safety precautions, and breaking them can have serious repercussions.

You can now start investigating the reason. Begin by verifying the fundamentals:

• make sure that the water supply valve was previously open;
• unhook the inlet hose from the water pipe and drain the remaining water from it;
• inspect the rubber, trying to notice defects, cracks, blockage or squeezing.

You must unplug the washing machine from the power source before doing anything!

We proceed if the issue was not found in the first instance. The mesh filter is the next in line. When the filter nozzle in the inlet hose becomes clogged, water cannot "pass" into the machine. In order to ensure that it is clean, you must:

• detach the hose from the machine body;
• find the mesh;
• take hold of the provided protrusion with pliers and pull the filter out;
• rinse the mesh under water, if necessary, clean it with a toothpick or toothbrush;
• return the nozzle to its place using pliers.

Checks are also made on the coarse filter. Since this component is installed after the tap, a few keys will be needed to clean it. While the other removes the fixing screw, one holds the valve’s junction. You should place a basin beneath it beforehand because, when fully unscrewed, water will pour out of the hole. The filter will clean itself when there is significant pressure applied; all you have to do is wait a minute and tighten the bolt again.

It can be annoying if your Bosch washing machine isn’t filling with water, but the problem is usually easy to resolve on your own. Make sure the water supply is turned on and that there are no kinks or obstructions in the hoses before proceeding. Another possibility is a malfunctioning water inlet valve or a clogged filter.

Occasionally, a malfunctioning sensor or the washing machine’s control board may be the cause of the issue. Many of these problems can be fixed with simple troubleshooting, but some may need to be handled by a professional. To prevent more severe damage to the machine, it’s critical to address the issue as soon as possible.

You can frequently get your Bosch washing machine operating again by following these instructions without having to pay for expensive repairs. Don’t be afraid to bring in a technician to have a closer look if the issue continues.
