If your Bosch washer reveals an e27 error code, this suggests a malfunction of the pressure sensor. The information is also called a pressure button or a water degree switch. If the stress button (level switch) stops working, the gadget can stop in the middle of the cycle. It refuses to proceed functioning. Generally, if there is a failure of the sensing unit, the only service is to replace it.

After changing the part, the e27 mistake code of Bosch washer will disappear. The component can not be fixed, but what happens if the trouble is not associated with it?
Significance and framework of the pressure switch
Considering that the primary component manages the work of the washing machine’s components, it does 2 features. It needs to provide a signal to quit water draining, and also close the inlet valve. Yet exactly how does the module recognize that the collected capacity suffices? The pressure switch regulates the amount of water that goes into the gadget. Each separate setting (washing or washing) calls for a particular quantity of water.
Pressostat is a plastic protected item of a round form. A tube, which is under pressure, and also wiring are attached to it. There is a slim membrane layer and also button inside the relay housing. The stress in the container depends on the amount of collected water. Air under stress travels through the hose pipe, it has an impact on the membrane layer, as well as it curves and also shuts the switch. With the assistance of wiring, the component receives a signal to stop the water intake.
Lots of individuals do not recognize where the stress switch is installed in the washer. Some of them think that it finds inside the container. As a matter of fact, the tool is set up at the top of the washing machine case, near the sidewall.
Checking the pressure switch for use
Initially, do the adhering to actions:
Observe general safety and security regulations. Detach your washing machine from the keys by ending from the outlet.
Tighten the inlet shutoff, which manages the water system.
To check the water level sensor, eliminate the top panel of the washing machine.
After eliminating the screws, slide the cover onward.
Leaving the panel aside, discover the sensor.
Loosen the screws that hold it, move the cover far from you as well as eliminate it. The sensor is installed with 1-2 screws, unscrew them, as well. Also, it is required to separate get in touches with as well as a pipe from the pressure button. To do this, loosen its clamp utilizing pliers.
Afterwards, examine the sensor making use of a tube, which is about 10 centimeters in length. The diameter of the part should coincide as that television, eliminated from the stress button before. Put one end of this tube on the inlet suitable, and also impact in the other side, using the stress button to your ear. You must listen to a couple of clicks (from one to 3 relying on your washer). It indicates the performance of the sensing unit. If there is silence inside the stress switch, then it does not function.
Examine the unit for damage. Inspect its hose for blockage. If there is obstructing, cleanse the opening under the tap water pressure.
Having seen to it that every little thing is all right, the last point to check is the multimeter. Establish the tester to resistance mode as well as attach the tester probes to the relay contacts. When the contacts are energetic, the numbers have to change. If they continue to be at the very same degree, the sensing unit is malfunctioning. To know which contacts to attach the tester, you need an electrical diagram of the device.
Stress switch self-repair
Occasionally, you can make modifications of the pressure button in your washer. In this case, there is no requirement to replace the component. Exactly how to continue:
It is essential to know just how much water needed for a cleaning device version to run each program. Based upon their number, the sensor is outfitted with one to 3 screws.
Complying with the required amount of water in the setting, it is needed to tighten up the screws.
Knowing just how to adjust the stress button, you can stay clear of purchasing a new part. However it is hard to determine the correct modification works with. The factor is that just the specialists at the plant do such job.
Pressure button substitute
Firstly, you need:
Disconnect all wires (take pictures or mark the links if needed).
Unscrew the bolts that safeguard the gadget to the body.
Detach the hose pipe
To attach a brand-new pressure switch, repeat all the action in reverse order.
Next off, you need to run the washing machine. Check if the new sensor is working as well as whether the e27 error code of the Bosch washing machine remains.
