As efficient and robust as they may be, even the dishwashers of significant brands are not immune to breakdowns. When the engine stops working, the cause of the dishwasher problem must be determined. This helps to know if the device can be repaired. For repair, contact a qualified repairman, then make sure that the damage problems are solved quickly. It should be noted that when a dishwasher breaks down, it shows an error code, which gives you an idea of the origin of the problem.
Power supply problem
The first instinct you have when the dishwasher won’t turn on is to check the electrical outlet. Make sure power reaches the connection point. The problem is not necessarily due to a fault in an engine component. If the electrical outlet is in perfect condition, unplug the device for about twenty minutes. If the appliance still does not turn on after reconnecting, the dishwasher problem is caused by a faulty part. In this case, the ignition switch is checked. This can damage and block the operation of the engine.
Lack of water supply
The dishwasher needs a large amount of water to work correctly. The distribution of household appliances can therefore find its cause in the water supply. Check if the machine is receiving the required volume of water. Check her plumbing installation, as well as the appliance conduits. They can indeed be blocked. It is also necessary to ensure that the water tap is not closed. On the other hand, the water inlet pipe includes a safety which is indicated by aqua-stop. Check that this part is also not defective.
Door lock damaged
To avoid any leakage during the washing cycle, the device is equipped with a sealed door with a locking system. This has an impact on the start of the dishwasher. When the door is properly closed, its hook presses a switch. As long as there is no contact between these two elements, the engine does not turn on. In this way, first, make sure that the door closes properly and that the hook is in perfect condition. If no anomalies are found with these components, the contactor is checked with a multimeter in the Ohmmeter position.
Malfunction of the pumps
The problem of washing dishes can also come from the failure of the pumps. The dishwasher has two: a cycle pump and a drain pump. The first is for washing, while the second is for water drainage. The device will not be able to operate if the pumps are clogged or broken. This is often due to lack of maintenance. After the pumps, please also check the solenoid valve. If the latter is clogged, the dishwasher cannot start. Also, the condition of the filter located between the water inlet pipe and the solenoid valve should be checked. In case of failure, the best option would be to replace it.
Faulty pressure switches and water distributor
The pressure switch is a part that measures the water level in the dishwasher. It transmits its data directly to the electronic card. As far as the information received from the board is not consistent, the machine stops. Still on the issue of water management, also ensure that the distributor is in good condition.
Electronic board failure
The electronic card is, in a way, the brain of the dishwasher. If this is faulty, the machine cannot be used. If, after examination, the functional components of the home appliance are in good condition, then the problem of washing dishes comes from the electronic paper. This product should, therefore, be replaced.
What are the most frequently replaced parts in a dishwasher?
The most crucial step will be to carry out the correct fault diagnosis to find the right part to replace. When it comes to a perforated cutlery basket, it is, of course, obvious, but when the device is leaking, how to understand the origin of this leakage and especially which part is faulty?
1. The cutlery basket
The cutlery basket is one of the most frequently used dishwasher accessories.
Why? Because it is often mishandled and can be damaged when filled, especially with sharp knives. Indeed, their blades directed towards the bottom of the basket can create holes in the bottom of the basket. The risk is then that these blades or cutlery handles pass through the basket and block the lower washing arm of the device.
2. The dishwasher door seal
Its lifespan depends on the quality of its maintenance. Indeed, it is essential to clean this element regularly once a month to eliminate the dirt that slips between the seal and the body of the device. Proceed with a cloth soaked in white vinegar to ensure its disinfection.
3. The washing arm or reel
Often, this part is one of the first to need replacement. Indeed, the washing arms are visible in the dishwasher and can be damaged by the dishes during loading. The lack of maintenance filters can also damage the equipment by blocking the water splash holes.
4. The cycling pump
Made up of a motor and a turbine, it will indeed give the impulses that will stir and push the water into the cavity of the device through the washing arms. Often, especially if the filters are not maintained regularly, debris will nestle in the pump and block the rotation of the impeller. This guarantees its failure! In this case, it will be necessary to access the cycling pump to remove the culprit(s). If the part is damaged, then it needs to be replaced.
5. The sewage pump
The drain pump also has an important role: it drains the washing water from your appliance. It is often located at the bottom of the dishwasher to evacuate all flows for perfect drainage. It is also sensitive to the lack of maintenance of the device and, in particular, of its filters, which in the long run, will allow dirt or small debris to pass until the pump is clogged. An engine can also damage that it no longer works, the drain pipe is blocked, or a propeller is stuck.
By repairing this device, one is choosing to extend its life. In doing so, they reduce the environmental consequences of building new equipment and disposing of the old. And at the same time, they usually save a lot of money.
