How to change the heating element in a Siemens washing machine?

It's almost impossible to miss a heating element failure in a Siemens washing machine. The machine stops heating, the cycle runs in cold water, and the user ends up with poorly washed laundry. Sometimes, the washing machine refuses to wash at all, displaying an error and freezing. The only solution is diagnostics and replacement of the heating element. We'll explain in more detail how to proceed.

Is the heating element difficult to reach?

Repairing a heating element is virtually impossible—it's easier and cheaper to replace the heating element in a Siemens washing machine. A new element isn't expensive, but it's important to select a replacement that matches the serial number of your existing machine. But first, you need to verify the part's fault by removing it from its housing and testing it with a multimeter.

The process of dismantling, diagnostics, and installation can be carried out at home, saving on the services of a repairman. In Siemens washing machines, the heater is located at the rear wall of the housing, which allows you to access it without disassembling the machine. The main thing is to take care of safety precautions and prepare for the replacement in advance.

We prepare everything necessary

To remove the heating element and perform diagnostics, you'll need a minimum of tools: a flat-head and Phillips-head screwdriver, a socket wrench, and a multimeter. Be sure to also prepare the washing machine itself for the upcoming repair:

• we disconnect Siemens from all communications (electricity, water and sewerage);
• we turn the body with the back wall forward;
• unscrew the bolts holding the rear panel;
• we disconnect the back from the body.

If your Siemens is still under warranty, you should call a specialist immediately; otherwise, you will lose your right to free service and repairs.

Before starting the repair, it's important to arrange for a replacement part. It's strongly recommended to avoid Chinese counterfeits and opt for genuine components. On average, a new heating element for Siemens ranges from $7 to $15. If the heating element breaks in a recently purchased machine, you shouldn't open the case yourself—you'll only need to call a specialist under warranty.

We check and replace the part

Replacing the heating element is a simple procedure, as it doesn't require disassembling the machine or any other complicated manipulations. Simply disconnect the Siemens from the power supply, unfold it, and remove the back panel. Next, look at the bottom of the housing—under the tank, there's a rounded connector with numerous wires running through it. This is the heater. Once the heating element is located, we begin diagnostics.

1. We turn on the multimeter in ohmmeter mode.
2. We apply the tester probes to the heater contacts.
3. We measure the resistance and compare it with the norm of 25-35 Ohm (if there are significant deviations, it means the heating element is faulty).

A faulty heater must be replaced. But first, we remember the location of the connected wires, and ideally, we take a photo or mark them. Let's continue working:

• we disconnect the terminals from the connector;
• loosen the central bolt with a wrench;
• we press the bolt inward;
• We pry the heating element with a screwdriver and remove it from the “nest”.

Next, we begin replacing the heating element. We clean the seat, reposition the temperature sensor, and secure the new element into its socket. We reconnect the wiring and the back panel, then connect the Siemens heating element and start the wash cycle. If the machine heats up, the repair has been completed successfully.
