Error codes for different dishwashers

Dishwasher error codes A modern dishwasher is a rather complex device, with dozens of compactly arranged components and sensors working in tandem. Such devices require an electronic self-diagnostic system that can quickly detect a malfunction and shut down the dishwasher before it gets worse. The system's job is not only to shut down a faulty dishwasher but also to alert the user to the problem using a special code—an error code. We'll examine error codes for dishwashers of different brands in this article.

Siemens dishwasher errors

Siemens dishwasher error codes cover the most common malfunctions that can potentially occur with any model of this brand. Let's review these codes, decipher them, and provide brief troubleshooting tips for the issues that triggered them.

E1, E2, E9, E11 – indicate that the dishwasher is unable to heat the water to the required temperature or heat the water at all. The following are possible causes: a faulty heating element, a faulty heating element triac, a faulty temperature sensor, or a broken water level sensor. How to fix: check the resistance of the heating element and sensors, and if necessary, clean the contacts or replace the heating element and sensors.
E3, E5 – The dishwasher is not filling properly. Causes: broken inlet valve, clogged inlet filter, tripped leak protection system, broken water level sensor. What to do: deactivate the leak protection system, while eliminating the cause of the leak, replace the pressure switch, replace the fill valve, clean the inlet filter.
E4 – problems with the pressure controller. Causes: no power is being supplied to the flow sensor or the flow sensor is faulty. The solution to the E4 error is to replace the flow sensor, repair any broken wiring, or clean the contacts.
E8 – Very little water in the tank. Causes: the drain hose is incorrectly connected (causing a siphon effect), or the water pressure is very low due to a clog or water pipe. What to do: Clear the clog and connect the drain hose strictly according to the instructions. The best way to do this is described in the article. How to connect a dishwasher to the water supply and sewerage system?
E15 – This error code occurs in dishwasher models with full or partial leak protection. E15 occurs if both the internal and external protection are triggered. In rare cases, a leak occurs at the junction of the Aqua Stop hose and the machine body, in which case E15 will not trigger. Solution: replace the damaged hose and repair the leaking body.
E16, E17 – Water fills the dishwasher automatically (by gravity). Causes: The flow sensor or inlet valve is broken, or there is too much foam inside the machine. Solution: Replace the flow sensor and inlet valve, and physically remove the foam from the machine.
E21, E24 – problems with water drainage. Causes: kinked or clogged drain hose, clogged or broken pump. Troubleshooting: replacing the pump, cleaning the drain hose and pump.

Please note! The codes for Siemens dishwashers are similar to those for Bosch dishwashers.

Krona and Hansa dishwasher errors

Now let's take a quick look at system errors for Krona and Hansa dishwashers. We'll provide examples of errors, their meanings, and briefly discuss how to troubleshoot them. Let's start with system errors for Hansa dishwashers.

The Hansa dishwasher self-diagnosis system is largely similar to the Siemens dishwasher self-diagnosis system, but there are some differences. The E1 code indicates that the machine is unable to fill with enough water within the allotted time. Reasons: the inlet valve or filter is clogged or broken, insufficient pressure. You can fix the error using the methods described above, namely, cleaning the filter, replacing the valve, or turning on the water more.

Error E4 on a Hansa dishwasher means there's too much water. Causes include a valve that doesn't close or a malfunctioning water level sensor. In this case, checking and replacing one of these components can solve the problem. Now let's look at the system errors found in Krona dishwashers, which also begin with the letter E. We won't cover the causes and troubleshooting steps, as they are similar.

E1 – the dishwasher’s leak protection system is activated.
E2 – waste water takes too long to go into the sewer.
E3 – the collected water cannot heat up to the temperature set by the program for too long.
E4 – too much tap water was poured into the dishwasher.
E5 – the thermistor is broken or there is no power supply to it.
E6, E7 – the heating element has burned out or there is no power supply to it.

Important! The decoding of errors E9, E10, E11, E12, E14, E15, and E17 for Krona dishwashers corresponds to the decoding of codes for Siemens dishwashers.

Miele and Kaiser dishwasher errors

Next on the agenda, we'll look at system errors in Kaiser dishwashers. These errors also begin with the letter E and are also numbered, but the codes have different meanings, so it's easy to get confused—be careful. E1—the dishwasher takes too long to fill the tank with water. E2—the dishwasher fails to drain the dirty water within the set time. The remaining error codes (E3, E4, E5, etc.) are the same as for Krona dishwashers (see the previous section).

Important! On some Kaiser dishwasher models, errors E1, E2, E3, E4, etc. are identical to errors E01, E02, E03, E04, etc.

Miele dishwasher system error codes differ from those discussed above. Let's take a look.

F01 – the heating element is short-circuited or the temperature sensor is burnt out.
F02 – the heating element fuse has tripped. It is necessary to check the resistance of the heating element and its electrical system, detect and eliminate the breakdown, and then replace the fuseAn article has been written about the detailed repairs Miele dishwasher repair.
F04 – temperature sensor (NTC sensor) is broken.
F11 – the Miele dishwasher is trying to remove water, but it does not drain, or drains extremely slowly.
F12 – tap water either does not fill the tank at all, or fills up, but very slowly.
F13, F14 – the pressure of the water entering the dishwasher is extremely low and the pressure of the water circulating in the machine is low.
F1E – there is no signal from the water flow sensor; most likely, the tap is closed or there is no water in the water supply.
F3E – interruptions in the operation of the pressure switch or heating element.
F78 – the circulation pump is jammed due to a blockage. In rare cases, the F78 error is caused by a faulty control board.

Please note: When a system error occurs in Miele dishwashers, it is accompanied by an annoying beep, followed by the dishwasher stopping operation.

Fagor dishwasher errors

Spanish dishwasher manufacturer Fagor also offers a diagnostic system. The error codes for these dishwashers are deciphered as follows:

F1 – error indicating that the dishwasher door is not closed.
F2 – there is no water in the dishwasher chamber. You should check whether the water supply tap is open and whether the water inlet system is clogged.
F3 – water does not drain from the machine, check the drainage system for blockages and the pump for functionality.
F4 – There's too much water in the chamber. Check the inlet valve and the water pressure at the faucet.
F5 – water overheated above the set temperature. We check the temperature sensor and the heating element.
F6 – The water isn't heating. You need to check the heating element, the heating element's triac on the control module, and the temperature sensor.
F7 – interruptions in the operation of the temperature sensor.
F8 – the sequential washing program does not work
F9 — incorrect operation when filling with water, possible failure of the pressure switch.
F10 – control board failure.

Electrolux Dishwasher Errors

Electrolux dishwashers have specific errors that differ from those discussed above. Here's a brief list of them:

i 10 – problems with filling the machine with water;
i 20 – problems with draining water from the machine;
i 30 – activation of protection against overfilling the machine with water, some decipher the i 30 error as the activation of the Aquastop system. In any case, to eliminate error code i 30, you will need to drain the water from the dishwasher tray;
i 50 – short circuit of the circulation pump triac;
i 60 – interruptions in water heating due to failure of the heating element or temperature sensor;
i 70 – break in temperature sensor;
i 80 – malfunctions in the control module memory;
i 90 – incorrect operation of the control board.

A detailed description and a complete list of errors can be found in the article. Electrolux Dishwasher Error Codes.

Whirlpool Dishwasher Errors

Lastly, we'll cover the system errors of Whirlpool dishwashers. Whirlpool dishwashers have some of the most advanced self-diagnostics, especially for modern display models. Here are the error codes and their meanings. dishwasher Whirlpool

E1, F2 – leak protection has made itself known.
E2 – problems with the electrical network voltage.
E3, F3 – power supply failures of the heating element.
E4 – temperature sensor burned out.
E5, F6 – filling the machine with water takes too long. Most often, the cause may be a breakdown of the Whirlpool dishwasher inlet valve or pressure switch. Sometimes the reason is that the user forgot to open the water supply tap.
F5 – The rocker arm is blocked. Check that the dishes are positioned correctly.
E6, F4 – water drainage is significantly difficult or absent altogether.
F1 – the thermistor works intermittently, poor contact.
F9 – water pours into the dishwasher without stopping.
FC – the water hardness sensor is broken. This error is only programmed into modern Whirlpool dishwasher models, meaning it's rare.
FA – the light indicator that determines the purity of the water is broken.

Finally, it's worth noting that all modern dishwashers from Bosch, Siemens, Hansa, and others feature a self-diagnostic program that contains roughly the same list of errors. This protects the appliance from fatal failure. Thanks to this program, the user can identify and fix the problem themselves, although not in all cases.
