Dishwasher owners are concerned about the ability of their dishwashers to repair themselves. In many cases, it is possible to diagnose problems such as abnormal operation, lack of water during the wash cycle, and other malfunctions without calling a professional. However, it is necessary to pay attention to specific malfunctions that may occur during normal operation of the dishwasher.
Why doesn’t the dishwasher wash well?
Among the dishwasher malfunctions that can be easily eliminated by the user is a noticeable decrease in the quality of the appliance. This is indicated by the appearance of whitish streaks and streaks on the walls of the dishes. Glassware and other glass objects after removal from the shelf do not become crystal clear, but remain cloudy. The cause of these problems can be a violation of the rules of operation of the equipment. However, most often it is simply the result of incorrect choice of detergent.
- In addition, a decrease in wash quality is always observed if the machine filters are dirty, clogged with dirt and debris.
When starting troubleshooting, proceed step-by-step according to the following scheme.
- Inspect the dishwasher.
- Empty its tank. Remove baskets and other external components.
- Unscrew the filters from their mountings.
- Remove the spray arms.
- Clean them thoroughly, rinse them with running water and brush them.
- Remove the filter screen from the supply hose. If it is dirty, the water pressure is weaker when rinsing and the dishes are not washed thoroughly enough.
Once all the necessary components have been installed, you can begin to investigate other possible causes of appliance deterioration. One such place to investigate is the rinse aid reservoir. If the reservoir is empty, white powdery residue may remain on glass and ceramic dishes after washing. Similar problems can occur if the reservoir is filled with a generic rinse aid instead of a specialized rinse aid.
- It is worth carefully studying the recommendations of a particular manufacturer on the choice of compatible chemicals, and when operating the equipment do not violate them.
If the dishes are heavily soiled, the heavily soiled areas must be handled by hand. Stacking order is also an important consideration. For example, only cups and glasses should be placed in the top rack. The bottom basket is for large dishes only, and the middle basket is for plates. It is important to follow this order to ensure optimum washing quality.
What to do, water remains inside the case?
It is not necessary to be concerned if small puddles of moisture are initially found inside the wash cabinet. The water can remain inside the appliance. It is important to maintain a normal microclimate inside the appliance so that the sealing rubbers remain elastic for longer. However, if a small puddle turns into a significant amount of liquid, becomes cloudy and contains food residues, it requires additional attention.
The cause of water stagnating in the sump may be one of the following faults.
- Improper connection of the outlet hose. If it is located too high, you will have to solve the problem by moving the outlet. It should be lowered by 35-40 cm from its previous position. The machine can then be started in test mode.
- This is caused by clogging of the water filtration system. It is enough to clean it to solve the problem. In the future, it is necessary to repeat these actions every 7-14 days.
- The pump or water level sensor is broken. In this case, it will be difficult to manage on your own. It is better to entrust the replacement of parts to the specialists of the service center.
- If the machine is not under warranty, and the breakdown is due to the pump (pump) or water level sensor, you can buy spare parts yourself. They can be original or copied – such variants are manufactured in Asian countries. They are cheaper, but do not guarantee normal operation of the equipment in the future.
Constant shutdown: solving the problem
One of the most unpleasant malfunctions that can occur in a dishwasher is a sudden shutdown. This fault usually occurs at the beginning or in the middle of a cycle. If a malfunction is detected in the operation of the equipment, the cause may be a temporary failure in the program or a power surge. The problem can be solved by using a specialized stabilizer to connect the equipment to the mains.
In the event of repeated power system shutdowns, the primary cause is likely to be the power system itself. There are several potential solutions to this issue. The initial step is to reboot the machine. To do so, simply press and hold the power button for 20 to 30 seconds. Once the current stabilizes, the dishwashing process will resume successfully.
In order to avoid possible leaks and interruptions in the electrical network, it is extremely important to properly organize the connection of electrical appliances. It is recommended to avoid using different electrical installation elements or models equipped with a fuse on the way from the socket to the body. In some cases, frequent disconnection of the appliance can indicate a possible breakdown of the heating element, which can also lead to the fact that the water will not heat up. The heating element may be damaged by lime deposits or burned out due to power outages. In such cases, the only true solution is to replace the damaged component.
Should these measures prove ineffective, it would be advisable to investigate the program unit. In dishwashers, it is this unit that is most susceptible to voltage fluctuations. In the event of a failure, the consequences will be irreversible.
- It is worth calling a specialist who will reinstall the software or offer to replace the damaged part of the device.
Other faults and their rectification
The diagnosis of insulation faults is a relatively simple process. In this case, a noticeable electric shock occurs on contact with the appliance connected to the mains. It is recommended to engage a qualified technician to diagnose the fault. If the control module board is faulty, further actions will be similar. Some faults can be eliminated without the use of specialized equipment. In other cases, especially if the equipment is beeping, making noise or showing other signs of abnormal operation, it is recommended to temporarily stop operation and contact a service provider. They will be able to diagnose and repair the equipment without making the problem worse.
Unregulated drainage
One of the signs that the appliance is constantly filling and draining water is a noticeable decrease in the quality of washing dishes. At the same time, according to external signs, the appliance functions as it should: the motor is running, water is filled and drained. Instead of starting the washing cycle, the opposite process is started. The recently filled water is quickly drained into the sewer. This leakage can be detected by monitoring the flow of liquid, as indicated by increasing meter readings.
- This problem is caused by a broken water inlet valve. If the valve is defective, fluid continues to flow even when the maximum allowable level is reached.
- The automation detects the overflow, then starts the pump to drain. The order of elimination of the problem in this case will be as follows.
- Turn the valve responsible for shutting off the water supply.
- Wait for the water to drain completely. De-energize the appliance.
- Reach the inlet hose. Remove it, disconnect the installed filter.
- Check the functionality of the inlet valve. This is done with the help of a multimeter. If the resistance values differ from the standard values (from 500 to 1500 ohms), the part will have to be replaced.
Please note that the inlet valve can only be reinstalled if the user is experienced in soldering parts. It must be understood that any changes to the electrical circuitry responsible for supplying power to the unit may result in more serious damage.
Hopefully, this post will give you some help in solving some typical dishwasher problems with your own hands. In case you doubt your repair skills, it is always better to contact professionals to protect your dishwasher from additional damage.
