Troubleshooting i30 error For Dishwashers

What to do when the dishwasher gives an I30 error? The main thing is not to panic, but to try to deal with the possible causes of the error. In this article, we will show you how to fix this problem yourself.

What does the fault code mean

The instructions for the Electrolux dishwasher briefly describe the I30 fault code. This error occurs when the overfill protection system is triggered. The description is rather superficial, because there are a large number of reasons for the occurrence of overflow. Which of the reasons served to stop the operation of the equipment is unknown.

It is necessary to select a list of causes of the malfunction in order to narrow the search circle. This is what we will do, but first you need to disconnect the device from the power supply.

First you need to inspect the unit for leaks. If there is a leak, find the source of the problem.

Next, inspect the garbage 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, pay attention.

You also need to inspect the drain pump for defects and blockages.

Inspect the filling hydraulic valve, it is probably clogged and cannot close completely, or even broken.

Cause of failure: leak

If a leak is found to be the cause of the equipment failure, you need to find the location of the malfunction. And only then understand the methods of troubleshooting. All dishwashers have a special tray where water flows when it flows. The first thing to do is look there. In the absence of water, this cause can be excluded, and proceed to the next step. Water got into the bottom of the hull? It is necessary to drain it, dry the pallet, and then:

  • Unscrew the top cover of the unit;
  • Remove the walls on the sides;
  • Start the equipment with the pallet on.

Why start up faulty equipment? This is the only way to see the place where the leak occurred. As soon as you identify a faulty element or system, you can remove the pallet and replace the faulty part. You can seal the leak with sealant. Experts do not advise this, because such repairs are short-lived. In the absence of the necessary part, or it is not possible to purchase it, such repairs can be carried out for a short time, rather than being completely without a dishwasher.

After applying the sealant, it is necessary to monitor the operation of the machine. Replace the damaged part as soon as possible.

Blockages

Having excluded leakage from possible problems of malfunction, you need to check the device for blockages. You need to start checking with the drain hose, as well as the sewer. This can be an obvious reason and it is not at all necessary to climb into the body of the machine. The hose can be removed and inspected visually. The sewer drain must be checked as follows:

  • Open the water supply tap with a sufficiently large pressure;
  • See how the liquid goes into the sewer drain;
  • In case of poor passage of liquid, clean the sewer with a plunger, or with a special cable;
  • In the case of a good passage of the liquid, we are looking for a breakdown in the machine itself.

Looking for the cause of the blockage

You need to start looking for clogs with a garbage filter. Very often, replacing or cleaning the filter can help find a solution to the problem. Error I30 occurs in twenty-seven percent of clogged garbage filters. It needs to be cleaned regularly.

The task of each owner of dishwashers, if you want to extend the life of the equipment:

Difficulties with the drain pump

Overflow may occur due to a malfunctioning 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 a 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 be the cause of the pump not pumping water well. In these two cases, it is necessary to disassemble the pump in order to check all possible options for equipment malfunction.

The dishwasher is equipped with an ion exchanger, but still the quality of the water inherent in our homes leaves much to be desired. Together with the supplied water, a huge amount of various impurities enter the unit, which, settling, harm the internal elements.

You need to remove the pump and disassemble it. Clean the impeller, check if it can rotate and assemble the pump. If the impeller is broken, replace it. If the replacement did not solve the problem, you need to ring the pump with a multimeter. If a malfunction is found, the pump must be replaced.

Filler valve malfunctions

Error I30, 3 blinks on the display, may be caused by a malfunction in the drain of the liquid, and interruptions in its supply to the machine. The inlet valve could break, which ensures the intake and discharge of water when it is opened and closed.

The following could happen to the valve:

  • Breakdown of electrics and electrical supply;
  • Breakage of the valve mechanism;
  • Clogged with debris, the valve cannot close completely.

It is necessary to disconnect the valve, disassemble it, clean the blockages and measure the resistance of the contacts with a special device – a multimeter. Check the electrics that power the valve. If damage is found, replace the valve or wiring.

Instead of total

So, we figured out the causes of the I30 error and what to do to fix it. We hope this information was useful and will help you avoid equipment breakdowns in the future.

Have a pleasant and beautiful life – with kitchen appliances that make life better!
