Why Is My Siemens Dishwasher Breakdown?

Jul 22, 2023, 12:03pm

If your Siemens dishwasher breaks down, won’t start, or doesn’t work properly, it’s likely that a component is faulty.

There are several possible causes of failure on a dishwasher:

  • The solenoid valve is faulty
  • The pumps no longer work
  • The resistance, the thermostat or the pressure switch no longer works

Depending on the model, the digital screen of the device can display “error code” or “fault code” messages which will allow you to identify the origin of the fault.

A Siemens dishwasher is known for its reliability and efficiency in providing clean and sparkling dishes. However, like any other appliance, it may experience breakdowns or malfunctions over time. Understanding the reasons behind the breakdown can help you identify and address the issues effectively. In this article, we will explore some common reasons why your Siemens dishwasher may experience a breakdown.

Why Is My Siemens Dishwasher Breakdown?

1. Power Supply Issues

One of the most common reasons for a dishwasher breakdown is a problem with the power supply. Check the following:

  • Power Connection: Ensure that the dishwasher is properly plugged into a working power outlet. Sometimes, loose connections or a tripped circuit breaker can disrupt the power supply.
  • Faulty Power Cord: Examine the power cord for any signs of damage or wear. If the power cord is damaged, it should be replaced immediately by a qualified technician.

2. Control Panel Problems

Issues with the control panel can lead to breakdowns or malfunctions. Check the following:

  • Control Lock: Some Siemens dishwashers have a control lock feature to prevent accidental button presses. Make sure the control panel is not locked, as this can prevent the dishwasher from starting.
  • Control Board Malfunction: The control board is the brain of the dishwasher, and if it malfunctions, it can disrupt the entire operation. If you suspect a control board issue, it is best to seek assistance from a professional technician.

3. Water Supply Problems

A properly functioning dishwasher requires a steady supply of water. Check the following:

  • Water Supply Valve: Ensure that the water supply valve to the dishwasher is fully open and that water is flowing through the supply line.
  • Water Inlet Valve: The water inlet valve is responsible for controlling the flow of water into the dishwasher. If the valve is clogged, damaged, or malfunctioning, it may not allow water to enter the dishwasher.

4. Drainage Issues

If the dishwasher is not draining properly, it can lead to breakdowns. Check the following:

  • Drain Hose: Inspect the drain hose for any clogs, kinks, or damage. A blocked drain hose can prevent water from draining out of the dishwasher.
  • Drain Pump: The drain pump is responsible for removing water from the dishwasher during the drain cycle. If the pump is faulty, it may not effectively drain the water, leading to breakdowns.

5. Heating Element Problems

The heating element in the dishwasher is responsible for heating the water during the wash and dry cycles. If the heating element is faulty, it can cause breakdowns or prevent the dishwasher from completing its cycles.

6. Mechanical Failures

Mechanical components, such as motors, pumps, and spray arms, can experience wear and tear over time, leading to breakdowns. If any mechanical part fails, it may affect the dishwasher’s overall performance.


In conclusion, a Siemens dishwasher may experience breakdowns due to power supply issues, control panel problems, water supply problems, drainage issues, heating element problems, or mechanical failures. By identifying the specific issue, you can take appropriate steps to resolve the problem. However, if you are uncertain about performing any repairs yourself, or if the breakdown is beyond your expertise, it is best to contact a professional Siemens dishwasher technician. They will have the knowledge and skills to diagnose the problem accurately and provide the necessary repairs to get your dishwasher back up and running efficiently, allowing you to enjoy clean and spotless dishes once again. Regular maintenance and prompt attention to any issues can help extend the lifespan of your Siemens dishwasher and prevent breakdowns in the future.
