Error E3 in the Krona dishwasher: decoding, elimination

Krona dishwashers are quite popular, so many users choose different models of this particular brand. Modern electronics work like a Swiss watch, and if any breakdown occurs, it is immediately notified by a coded notification on the device display. For example, error E3 often occurs in a Krona dishwasher, for which there are several causes. What kind of error this is and how to properly eliminate it should be known to all users who have dishwashers of the specified brand at home.

Transition to service test on Bosch PMM machines

Since the names of the buttons on the control panels of different Bosch PMM models may vary, we have prepared a summary table that shows the buttons used to put the dishwasher into test mode.

To switch to test mode, you need to press and hold the buttons shown in the table (2nd and 4th from the left), and then turn on the machine by pressing the on/off button. Press the indicated buttons again to run the test program. Wait until the program finishes and the error code is displayed. To exit test mode, turn off the machine.

In fully built-in models, you need to open the door to enter test mode, and close it to start testing.

The list of models in the tables is far from complete, but the general principles are valid for almost all Bosch PMM models. We will describe some of the features a little further in this article, in particular, we will tell you how to run a test program on PMMs that do not have buttons, but only have a washing program selector knob.

Ways to prevent dishwasher breakdowns

Although the Ariston Hotpoint is a very reliable dishwasher, operating errors can damage it too. The technician will “report” on all types of possible malfunctions in a timely manner; you just need to understand the nuances of deciphering the codes in order to determine the necessary and sufficient measures to eliminate the cause of the malfunction.

And in order not to become a regular customer of repair shops, you just need to follow the operating rules and follow a few tips that will extend the life of the equipment.

Recommendations for use:

• Ariston Hotpoint has filters that purify water from various impurities. To avoid clogging, they must be cleaned in a timely manner.
• It is recommended to install a grease filter at the entrance to the sewer to avoid external blockages.
• To make the machine easier to operate, wipe the dishes with a napkin before loading to remove any remaining food.
• If your water supply has hard water, use regenerating salt softeners or install a special filter at the inlet to the PMM.
• Do not use soap, shampoos or other substances not intended for dishwashing equipment as cleaning ingredients. Only specialized detergents with characteristic low foaming are suitable for operating the dishwasher.
• Do not overload the dishwasher with items. You should strictly follow the manufacturer's recommendations for loading the dishwasher given in the data sheet.
• After each start of the machine, wash and dry the tablet tray.
• Place dishes so that they do not touch or block the spray arms.

And the last piece of advice - at least once a month, arrange a “clean day” for your assistant, running it in idle mode along with a cleanser and disinfectant.

Fault marking meaning

It would seem that everything was done correctly: all the necessary ingredients were added (from salt and rinse aid to the appropriate detergent). The device will turn on and water will flow through its hoses. However, literally five minutes later a message appears about error code E1.

To get started, you can refer to the instructions. The transcript provides data on long-term activation or closure of the valve. The latter means that no water is supplied. This can happen for the following reasons:

• low water pressure at the inlet from the water supply system;
• it is necessary to check the sensors;
• If the above points are denied, the malfunction may be due to a broken electrical circuit inside the device.
