Electrolux dishwasher error code i30

Instructions for using the Electrolux dishwasher gives a brief explanation of the i30 error code. It seems like the i30 code indicates that the Electrolux overfill protection has tripped. The characteristic is rather poor, given that there can be quite a lot of reasons for overflow. How to understand what exactly happened to the device?

Electrolux dishwasher error code i30 (or 30)

  • It is necessary to examine the dishwasher for leaks, and if any, look for the places where these leaks originated.
  • Inspect the garbage filter and the drainage line for obstructions.

By the way! Clogging can occur not only in the dishwasher but also in the sewage system. The dishwasher will also respond with an i30 error.

  • Inspect the drain pump for obstructions and damage.
  • Check the filling valve, it may be clogged and does not close until the end or even failed.

It’s All About Leaking

So we determined the list of possible problems that generated the i30 error code, now you have to find a specific malfunction that has arisen in your device, and then figure out how to eliminate it.

The majority of Electrolux dishwasher models have a tray where water is collected in case of leakage. The first thing you need to do is to check it for water. If there is no water, then skip this step and proceed to the next one. If there is water, drain it, dry the pallet with a hair dryer, and then:

  1. Unscrew the top cover;
  2. Remove the side walls;
  3. Do not remove the pallet, and run the dishwasher.

Why start a faulty dishwasher, and even in half-disassembled form? How you can see where the water runs or drips? Once you can determine the flowing part, carefully remove the tray and replace the defective element. In extreme cases, you can cover the leaky place with a sealant, although experts strongly do not recommend doing this because such repair is short-lived.

But if there is no possibility to buy it in the near future, such repairs are better than being left without a dishwasher at all. If you are forced to use a sealant for temporary repairs, carefully monitor the dishwasher during operation. However, it is recommended to immediately replace the damaged part when it is possible.


After making sure that there is no leakage, check the dishwasher for clogs. It is best to begin to check not even the dishwasher itself but a drain hose and sewer, it’s easier than getting inside the case. The hose is removed and inspected visually.

You can check the sewer drain as follows::

  • open the tap, ensuring a decent head of water;
  • check how the water goes into the sewer;
  • If water does not drain, then clean the sewage system with a plunger or cable; if the water goes well, look for clogging in the dishwasher.

Start searching for clogging in the dishwasher with a garbage filter. Replacing and cleaning the dishwasher filter usually helps to solve this type of a problem. According to the statistics, the code i30 appears precisely in half of the cases because of the garbage filter. So its regular cleaning is a priority task even during the normal operation of the dishwasher, not to mention the cases when the breakdown occurred.

Next, we need to remove the tray and check all branch pipes and other elements. Such work is scrupulous and requires some effort and time.

Drain Pump Problems

Overflow can also occur due to the drain pump. The pump can work poorly or not work at all. Usually, the i30 error code comes out if the pump is clogged with something, that is, the impeller is blocked by foreign objects wound up on it, or by a water stone. It is also possible that the impeller is damaged and requires replacement. And in either case, the pump should be checked, and depending on what the disassembly of the part shows, make a decision.

Despite the fact that the dishwasher Electrolux has an ion exchanger built in, the water quality leaves much to be desired. A lot of impurities enters the machine with water, which in time spoils internal parts.

Disconnect the pump, disassemble it and examine. Remove the blocked impeller, check the rotation and collect the pump back. If the impeller is broken, change it to a new one. If the impeller is OK but the pump does not visible damage, you should examine it using a multimeter. If you find a malfunction, you need to replace the pump completely.

Fill Valve Is Out of Order

The problems that caused the I30 error may not be related to the violation of the water discharge. The reason may be in violation of the flow of water through the valve in the dishwasher. The filling valve could fail, which opens when water is needed and closes when no water is needed.

With the valve, the following things can happen:

  • an electrician or electric wire break down;
  • mechanism failure;
  • the mechanism can be clogged with garbage from which the valve will stop closing completely.

Remove and disassemble the filling valve. Check the valve for blockages, measure the resistance of the contacts with a multimeter, examine how the mechanism works. Also, you need to check the wires. If a fault is found, either change the wiring or replace the valve.
