What to do when the dishwasher gives an I30 error? The main thing is not to panic, but to try to figure out the possible causes of the error. In this article we will tell you how to fix this problem yourself.
What does the fault code mean?
The instructions for the Electrolux dishwasher briefly describe DTC I30. This error occurs in the event of an overfill protection system. The description is quite superficial, because there are a large number of causes of overflow. Which of the reasons served to stop the operation of the equipment is unknown.
It is necessary to highlight the list of causes of the malfunction in order to narrow the search circle. This is what we will do, but first we need to disconnect the device from the power supply.
First you need to inspect the unit for leakage facts. If a leak occurs, find the location of the problem.
Next, inspect the trash filter, as well as the drain path, to eliminate the possibility of clogging.
Attention: Not only in the machine itself, clogging can occur, but also in the sewer. In this case, the equipment will also display an I30 error on the display, you need to be very careful and pay attention.
You also need to inspect the drain pump for defects and blockages.
Inspect the bulk hydraulic valve, it is probably clogged, and can not close to the end, or even broken.
Failure reason: leak
If a leak is detected as a cause of equipment failure, you need to find the place of the malfunction. And only then to understand the methods of eliminating the breakdown. All dishwashers have a special tray where water flows when it flows. The first step is to look there. In the absence of water, this reason can be eliminated, and proceed to the next step. Has water collected in the bottom of the hull? It is necessary to drain it, dry the pan, and then:
- Unscrew the top cover of the unit;
- Remove the walls on the sides;
- Start the equipment with the drip tray on.
Why launch faulty equipment? Only in this way is it possible to see the place where the leak occurred. Once you identify a defective item or system, you can remove the pan and replace the defective part. You can seal the leak with a sealant. Experts do not recommend this, since such repairs are short-lived. In the absence of the necessary part, or there is no opportunity to purchase it, for a short time you can carry out such repairs, rather than remain completely without a dishwasher.
Applying sealant, it is necessary to monitor the operation of the machine. As soon as possible, replace the damaged part.

Clogging
Having excluded the leak from possible problems of the malfunction, it is necessary to check the device for blockages. You need to start the test with a drain hose, as well as a sewer. This can be an obvious reason, and you don’t have to climb into the car body at all. The hose can be removed and inspected visually. Sewer drain must be checked in this way:
- Open the water tap with a sufficiently large pressure;
- Watch how the liquid goes into the drain of the sewer;
- In case of poor fluid passage, clean the sewer with a plunger, or using a special cable;
- In case of good fluid passage, we are looking for a breakdown in the machine itself.
We are looking for the cause of clogging
You need to start looking for clogging with a trash filter. Very often, replacing or cleaning the filter can help find a solution to the problem. I30 error occurs in twenty-seven percent of cases of clogged debris filter. You need to regularly clean it.
The task of each owner of dishwashers, if you want to extend the life of the equipment:
Inspect all nozzles and systems of the machine, while removing the pallet. This work requires time and knowledge. Therefore, it would be more correct to provide repairs to a specialist who will perform the work professionally and very quickly.
Difficulty with the drain pump
Overfilling may occur due to malfunctioning of the drain pump. It may not work at all or work intermittently. An error in the operation of the machine occurs due to clogging of the pump, when foreign objects or formed water stone interfere with the operation of the impeller. It may be necessary to replace the impeller if it is damaged, as this may cause poor pumping of the water. In these two cases, it is necessary to disassemble the pump in order to check all possible options for malfunctioning equipment.
The dishwasher is equipped with an ion exchanger, but still the quality of the water inherent in our homes leaves much to be desired. A huge amount of various impurities enters the unit together with the supplied water, which, when deposited, harm the internal elements.
It is necessary to take out the pump and disassemble it. Clean the impeller, check if it can rotate, and assemble the pump. If the impeller breaks, replace it. If the replacement did not solve the problem, you need to ring the pump with a multimeter. If a malfunction is detected, replace the pump.
Bulk valve malfunctions
Error I30, 3 blinks on the display, may be caused by a malfunction of the fluid drain, and interruptions in its supply to the machine. The filling valve, which provides a set and drain of water during its opening and closing, could break.
The following could happen to the valve:
- Damage to electricians and electrical connections;
- Damage to the valve mechanism;
- Clogged with debris, the valve cannot close completely.
It is necessary to disconnect the valve, disassemble it, clean the clogs and measure the contact resistance with a special device - a multimeter. Check the electrics that feed the valve. If damage is found, replace the valve or wiring.
Instead of a total
So, we figured out the causes of the error I30 and what to do to fix it. We believe this information was useful and will help to avoid equipment breakdowns in the future.
Have a nice and beautiful life - with kitchen appliances that make life better!
