If your Bosch washer reveals an e27 mistake code, this indicates a malfunction of the stress sensing unit. The information is additionally called a pressure switch or a water degree switch. If the pressure button (level button) stops working, the gadget can stop in the middle of the cycle. It refuses to continue working. As a rule, if there is a failure of the sensing unit, the only remedy is to replace it.
After transforming the part, the e27 error code of Bosch washer will disappear. The element can’t be fixed, however what if the trouble is not related to it?
Significance as well as structure of the pressure switch
Because the major component controls the job of the washing machine’s components, it does 2 features. It has to give a signal to stop water draining, and likewise close the inlet shutoff. Yet how does the module understand that the gathered capacity suffices? The pressure switch regulates the quantity of water that goes into the tool. Each separate mode (cleaning or washing) requires a specific amount of water.
Pressostat is a plastic protected piece of a round form. A hose pipe, which is under pressure, as well as electrical wiring are attached to it. There is a slim membrane and also button inside the relay real estate. The stress in the tank depends on the amount of collected water. Air under pressure travels through the hose pipe, it has an effect on the membrane, and also it curves and also shuts the switch. With the assistance of wiring, the component gets a signal to quit the water intake.
Many individuals do not recognize where the stress button is mounted in the washing machine. A few of them assume that it finds inside the storage tank. Actually, the device is established at the top of the washer instance, near the sidewall.
Examining the pressure button for service
Initially, do the following steps:
Observe general security guidelines. Disconnect your washer from the mains by pulling the plug from the outlet.
Tighten the inlet valve, which handles the supply of water.
To test the water degree sensing unit, remove the top panel of the washing machine.
After eliminating the screws, slide the cover ahead.
Leaving the panel apart, find the sensing unit.
Unscrew the bolts that hold it, slide the cover away from you and eliminate it. The sensing unit is mounted with 1-2 screws, loosen them, as well. Also, it is necessary to detach calls and a hose pipe from the pressure switch. To do this, unscrew its clamp utilizing pliers.
Afterwards, examine the sensor using a pipe, which has to do with 10 centimeters in size. The size of the part ought to be the same as that the tube, removed from the stress button previously. Put one end of this pipe on the inlet suitable, and also strike in the other side, using the stress button to your ear. You must listen to a couple of clicks (from one to three depending on your washer). It indicates the efficiency of the sensor. If there is silence inside the stress switch, after that it does not work.
Examine the device for damages. Inspect its hose pipe for blockage. If there is obstructing, clean the hole under the tap water stress.
Having made sure that every little thing is okay, the last point to inspect is the multimeter. Establish the tester to resistance setting and attach the tester probes to the relay calls. When the contacts are active, the figures must change. If they continue to be at the same level, the sensing unit is defective. To understand which calls to link the tester, you require an electrical diagram of the gadget.
Pressure switch self-repair
Sometimes, you can make modifications of the pressure switch in your washer. In this instance, there is no need to change the component. Exactly how to continue:
It is essential to understand how much water needed for a washing machine version to run each program. Based on their number, the sensor is equipped with one to three screws.
Adhering to the needed quantity of water in the mode, it is essential to tighten the screws.
Knowing how to readjust the stress button, you can stay clear of purchasing a repair. Yet it is not easy to calculate the appropriate modification coordinates. The point is that just the professionals at the plant do such work.
Stress switch substitute
First off, you require:
Detach all cables (take images or mark the connections if required).
Loosen the bolts that secure the gadget to the body.
Detach the hose
To attach a brand-new pressure switch, repeat all the action in reverse order.
Next, you need to run the washer. Examine if the brand-new sensor is working and also whether the e27 mistake code of the Bosch washer stays.
