The E01 error code usually denotes a malfunction with the heating element or any associated parts of the dishwasher.

We’ll go over the typical causes of the E01 error in this guide, along with step-by-step instructions on how to fix them. Whether your dishwasher needs a basic reset or a more thorough inspection, we can help you get it back in working order.

The Error E01 code on your Bosch dishwasher usually denotes a heating system issue with the appliance. This error typically indicates a problem with the thermostat or heating element, which can hinder the thorough cleaning of your dishes. To fix this error and make sure your dishwasher is operating properly, you should usually check and possibly replace the thermostat or heating element.

Where did this code come from?

The Bosch dishwasher code E01 denotes that water heating is not possible. A malfunctioning heating element is the most frequent source of the error; the temperature sensor is more frequently to blame. Occasionally, the loose contacts cause the connection between the control board and the heating element to break.

It is necessary to replace a burned-out heating element because it cannot be repaired.

What should you do if the dishwasher’s display displays this error code? First, see if the washing chamber’s water is heating up. You will need to access the heating element and run its diagnostics if it is cold.

The thermistor may not be operating properly if the water in the washing chamber is hot. Inaccurate data is transmitted to the control module by a damaged sensor. notifies that although there is heating, the water is cold. Resetting the error can be aided by replacing the thermistor.

The heating element and circulation pump are housed in the same housing in Bosch dishwashers. Without taking the appliance apart, you can diagnose the heating element. We will instruct you on how to resolve the dishwasher’s error on your own.

Restarting the dishwasher and checking the heating element

Prior to anything else, confirm that the Bosch dishwasher is displaying the E01 error for a valid reason. Rebooting the device allows you to verify this. Using the button, turn off the dishwasher. Then, remove the power cord from the outlet and give it a good fifteen to twenty minutes. After that, turn the dishwasher back on. If the code is still on, there is a malfunction and you will need to have the machine diagnosed.

In Bosch dishwashers, the heating element and circulation pump are housed in the same housing. The assembled unit costs between 4,500 and 12,000 rubles. Consequently, it is preferable to purchase replacement parts only after confirming that the issue is indeed a malfunctioning heating element.

To identify the heating element’s condition:

• de-energize the dishwasher;
• close the valve responsible for supplying water to the machine;
• disconnect the dishwasher from utilities by unhooking the hoses;
• pull the dishwasher out to a place where it will be convenient to work with it;
• remove the dish basket from the hopper;
• pull out the dishwasher trash filter;
• unscrew the bolts securing the side wall of the device, remove the panel and set it aside;
• turn the machine upside down;
• remove the sound insulation from the side wall;
• remove the springs of the dishwasher door soft opening mechanism;
• Use a screwdriver to remove the dishwasher tray;
• Disconnect the float sensor connectors;
• unhook the filling pipe.

The dishwasher’s circulation pump will be visible once the bottom is removed. There are pipes and wires attached to this rather sizable unit. It is not required to take the component out of the dishwasher body in order to diagnose the heating element.

On the recirculation pump’s housing are the heater contacts. Multimeters are specialized instruments used in diagnostic procedures. The tester must be turned to the ohmmeter mode before you can measure the resistance the heating element produces by connecting the probes to the terminals.

The resistance of a functional heating element should be between 21 and 22 Ohms.

A heater breakdown necessitates replacement if the multimeter display reads zero, one, or an infinite number. It is worthwhile to look for any breakdowns in the heating element when the tester readings are normal.

The multimeter is set to the megohm measurement mode in order to accomplish this. Next, one of its probes is pressed up against the heating element’s power contact, and the other is pressed either against the body or the ground. The tester display’s readings should tend toward infinity if the heater is operating correctly.

Applying the multimeter probe to a dry heating element is crucial. The readings will be inaccurate if the heater body is damp. Therefore, ensure that the element is dry during the diagnostic process.

Once it has been confirmed that the Bosch dishwasher’s malfunctioning heating element is the source of the error code, replace the circulation pump. Invite an expert and pay him for diagnostics if you are unsure. Your guess will be verified or denied by the master.

While receiving an E01 error on your Bosch dishwasher can be annoying, you can better handle the situation by knowing what it signifies and how to fix it. This error usually means that there is a problem with the heating element, which is necessary to clean your dishes properly. This error typically indicates that the dishwasher isn’t heating the water to the proper temperature.

Start by examining the heating element for any obvious damage or obstruction in order to fix the E01 error. Debris or mineral accumulation can occasionally cause issues with its operation. If you feel competent performing simple appliance repairs, you may also wish to check the security of the wiring connections. If you’re not sure or the issue continues, it’s a good idea to contact a qualified technician. They are better equipped to diagnose the problem and, if necessary, replace any damaged parts.

Errors such as E01 can be avoided in the future with routine care and maintenance. Your dishwasher’s lifespan and efficiency can be extended by keeping it clean and making sure all of its parts are operating as intended. If in doubt, consult the user manual or get expert assistance to maintain the proper operation of your dishwasher.
