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

This can be due to several causes:

  • Lack of supply
  • Failure of the water management system
  • Heating system malfunction
  • Locking or sealing problem
  • Electronic board or power supply problem

The dishwasher is arguably one of the most hardworking appliances in the modern kitchen. It takes on the arduous task of scrubbing dishes, freeing us for more leisure or other productive activities.

Unraveling the Mysteries of Smeg Dishwasher Breakdowns: Common Issues and Solutions

Frequent Causes of Breakdown

Smeg dishwashers, like any other brands, can succumb to various mechanical or electrical issues. Let’s delve into some of these common problems:

  1. Improper Loading: Overstuffing the dishwasher or not arranging dishes properly can prevent it from cleaning effectively. In some cases, improper loading can even damage the dishwasher’s interior parts.
  2. Drainage Problems: A dishwasher that isn’t draining correctly often points to a blocked filter, a clogged drain hose, or a faulty drain pump. This could cause the machine to stop mid-cycle or not start at all.
  3. Water Supply Issues: If your dishwasher is not filling with water as expected, the culprit could be a defective water inlet valve, a kinked hose, or issues with your home’s water pressure.
  4. Faulty Control Panel or Software: If your dishwasher is acting up, randomly changing cycles, or refusing to start, the issue might lie in the control panel or software.
  5. Malfunctioning Heating Element: If your Smeg dishwasher is failing to clean dishes properly or leaves them damp, it could indicate that the heating element, responsible for heating the water and drying the dishes, isn’t functioning correctly.
  6. Wear and Tear: Regular use can lead to wear and tear of the dishwasher’s components like racks, spray arms, door seals, etc., which could eventually lead to a breakdown.

Prevention and Solutions

To avoid Smeg dishwasher breakdowns and keep your appliance running optimally, consider the following steps:

  1. Regular Maintenance: Regularly clean the filters, check the spray arms, and inspect seals to ensure smooth operation. Preventive maintenance can save you from more significant problems down the line.
  2. Proper Loading: Load your dishwasher as per the manufacturer’s instructions, ensuring that the spray arms can move freely and water can reach all the dishes.
  3. Address Drainage Issues: If your dishwasher isn’t draining properly, check and clean the drain filter and hose. If the problem persists, the drain pump may need replacing.
  4. Check the Water Supply: Make sure that the water supply hose is free of kinks and blockages. If your dishwasher still isn’t filling properly, you might need to replace the water inlet valve.
  5. Professional Repair for Electronic Issues: If you suspect that the issue is with the control panel or software, it’s best to contact a professional. They can diagnose and fix the issue, and even update the software if needed.
  6. Check the Heating Element: If the dishwasher isn’t cleaning or drying dishes effectively, have a professional check and, if necessary, replace the heating element.
  7. Replace Worn-out Parts: Regularly inspect your dishwasher for worn-out parts. Replacing them in a timely manner can prevent further damage and prolong the lifespan of your appliance.


The main components of this system are the pressure switch, the resistance and the thermostat.

  • The pressure switch detects water and regulates its volume. This part also controls the operation of the thermostat.
  • The resistance takes care of heating the water.
  • The immersion heater or thermostat stops the resistance when the water reaches the right temperature.

The dishwasher has a door equipped with a locking system with a switch.

  • The contactor allows the machine to detect that the door is properly closed. Start-up can thus be initiated.
  • Insofar as the contactor is defective, the motor remains inactive: it must be tested.
  • Sealing problems can also be a source of failure. In this case, the replacement of the seals is necessary.


The plate, the module or the electronic card make up the machine’s control panel. They allow you to choose the different operating modes and to program the ignition of the machine.

  • If the card is damaged, the dishwasher cannot operate.
  • Always check the power supply in the event of a dishwasher failure.

In summary, knowing why your Smeg dishwasher might breakdown is a critical step towards addressing and preventing the issue. Regular maintenance and appropriate use are key to ensuring the longevity of your dishwasher. However, when a problem arises that you cannot fix, it is wise to seek help from professional repair services. Remember, taking good care of your Smeg dishwasher means ensuring a smooth, hassle-free dish cleaning experience for years to come.
