Miele Washing Machine Error Codes

Below is a list showing Miele washing machine error codes, a possible cause for the error code, and how to correct the problem. These error codes are displayed on the washer’s screen whenever there is a problem with the washing machine. Instructions and information provided in this guide are meant to help users of Miele washing machine.

F11 error code – Drainage Fault

Fault code F11 is triggered when the ball in the non-return valve within the washer’s sump has not opened or when the water in the washer cannot be drained. A buzzer is activated for 120 seconds when this error is displayed.

The washer’s circulation pump runs for 2 seconds after every drain pump step. This is followed by an inspection of the water levels by the heater pressure switch B1/13. If the water level is very high, the machine extends its drainage period. If the water level does not subside despite this extension, the program will be interrupted and the fault code displayed on the washer’s screen. The drain pump will also be activated. Miele washer will also display the F11 error code when the heater relay 1K1 fails to be activated after error code F51 register check or when the drain hose is kinked.

Correct error cod F11 by ensuring the drain hose has been positioned correctly. Also, clean your washer’s on-site drain; inspect the filters, sump drain, filters, and the heater pressure switch. Replace the heater pressure switch where necessary.

Water in the Base – There’s an anti-flood device that sits in the bottom of your washing machine. When the drain pan fills up with water, a float rises. The float is pushed to a certain level, the anti-flood device is triggered and this causes water to drain out onto the drain pan. This is a safety feature that stops the electrics above the bottom of the pan from getting wet. If you notice that your washing machine continues to drain after you turn it on, there’s probably a leak that’s filling the drain pan with water which is activating the anti-flood device.

To get water out of the base and fix the F11 error on your washing machine.

  1. Turn off the power. Make sure the washing machine is unplugged so that you don’t accidentally electrocute yourself.
  2. Take off the base plate. There’s a base plate at the bottom of the washing machine. You’ll need to turn the washing machine on its back to see the base plate. The base plate is attached to the washing machine using two or four screws. You need to unscrew the screws that are attaching the drain pan to the bottom of the washing machine.
  3. Remove any water from the base. Once you’ve removed the base plate, you need to remove water from it using a bowl and a sponge. This will dry up all of the unnecessary water in the drain pan. You could also leave your washing machine unplugged and left to sit for about a week. This should allow enough time for the water to naturally evaporate which will leave you with a base that’s dry. The downside to this is that you won’t be able to use your washing machine for about a week.
  4. Find the source of the leak. Once you’ve removed all of the water, you’ll need to know what’s causing the leak. To test for a leak, you need to turn on the washing machine and let it fun a cycle, from here, look out for leaks. Once you find the source of the leak, then you’ll know why your washing machine is leaking. Once found, you can turn off the machine.

After finding the leak, if you’re not sure how to do the repair yourself to stop water from going to the bottom of the washing machine, then you need to look at your frigidaire manual to check how to fix the leak to stop the error F11 from showing, then you’ll need to hire a professional.

Drain Hose Is Lower Than The Water Level – If the end of the drain hose is set at a level lower than the water level in the washing machine, it is going to allow the water to drain away. The water level usually fills to just below the door seal, so if you’ve got the end of the drain hose set to a level that’s lower than that – it is going to run out of the machine.

Don’t worry if this is the case with your washing machine though, as it can be easily corrected. All you need to do is simply lift the drain hose to a level that is higher than the water level in the appliance.

Most drain hoses come supplied with a crook attachment, and you can use that when setting the drain hose into an open pipe drain, so make sure that the hose doesn’t go too far down to create a siphon effect.

To fix a drain hose that is below the water level:

  1. Look at your drain hose. Look at the drain hose and check if it’s lower than the door seal. This will let you know if it’s the drain hose that causes your washing machine to not stop draining.
  2. Use a crook to adjust the hose. Your washing machine drain hose could come with a crook attachment which you can use to adjust the hose to make sure that it doesn’t go too far into the drain pipe. If you’ve managed to adjust the hose using the crook, this will prevent the siphoning.
  3. Test it out. Once the drain hose has been adjusted using the crook, then you can test it out. If the hose is working properly and the washing machine stops draining when it’s supposed to, then you’ve fixed the problem.

Blocked Drain System – At times, error code F11 shows up to indicate a drain problem in the appliance. When this happens, you need to begin by inspecting the washing machine sewage system and the area below the sink where a connection between the washing machine and your home’s piping has been made. You need to open it up and remove the filters for cleaning. Inspect the hoses for folding and blockage while at it.

Faults with the Drain Pump – A washing machine may overfill because of a malfunctioning pump. In most cases, fault code F11 occurs when the appliance’s impeller is broken or blocked. When this happens, you need to disconnect the washing machine pump and remove everything blocking the blades. If the pump’s impeller is broken, you need to replace it with a new one. If there is no visible damage to the pump, you need to examine the subunit using a multimeter. If the subunit does not have continuity, you need to purchase a new drain pump.

Faulty Pressure Switch –  Sometimes the pressure switch (view on Amazon) becomes clogged with fat or food and sends the wrong signals to the washing machine’s control board, making it think the tank is empty. Therefore, the system does not create a command for its intake valve, preventing the membrane from closing. Water continues to flow into the washing machine. It spills and enters its pan. The leakage sensor picks up the problem and responds to it by sending a signal to the main control, which displays the F11 error code. You need to clean the pressure switch to correct this problem. However, if the sensor has broken down, you need to replace it to fix the issue.

F01 error code – Water/Heating NTC or Leads Open-Circuited

This fault code is triggered when the NTC temperature sensor R30 (View on Amazon) breaks down. It will also be displayed when connections leading to the sensor R30 short-circuit. When this error code is triggered, your washing machine will not activate heating, which will inhibit its rinse aid from being dispensed. This error is displayed as Technical fault F01, and the machine’s buzzer turns on for two minutes as the error code is displayed on the screen of the washer.

To correct the F1 error code, you need to inspect both the temperature sensor and all its connection leads for faults within the system. Check the resistance of the temperature sensor. It should be at 14.9kΩ (± 750Ω) when the temperature sensor has a 68°F temperature. The resistance should reduce to approximately 12kΩ (± 600Ω) when the temperature increases to 77°F. It would help if you also inspected the plug connections of your washer. In extreme cases, replace the temperature sensor in its entirety.

F02 error code – Water/Heating NTC or Leads Open-Circuited

Fault code F02 is displayed on the screen of your washer when there is an open circuit in the NTC temperature sensor R30, and its connection leads. When this error occurs, the washer’s buzzer activates for 120 seconds. Like the F01 error code, you Miele washer will not activate heating. In addition to this, it will not dispense its rinse aid. Inspect the temperature sensor, and its connection leads for potential weaknesses. Additionally, it would help if you got the resistance measurements of the sensor. It should have an average resistance of 14.9kΩ and 12kΩ when its temperature is at 68°F and 77°F respectively.

F12 error code – Water Intake Fault at Start of Step

Fault code F12 is triggered when the on-site shutoff valve is closed, or the on-site water supply is not in order, or the water inlet valve is broken, or the electrical connection has open-circuited, or when the B3/4 flow meter does not provide pulses. A minimum of fifteen pulses through B3/4 (flow meter) need to be recorded in the first five seconds of the water intake step. If these pulses are not detected, the error code F12 is displayed on the screen.

There are various ways of fixing this problem. They include opening the shutoff valve, checking the on-site supply of water using a specialist, and checking the waterproof system valve Y2. You also need to pull out the left side panel and inspect if the plate with reed switch on the B3/4 flow meter is properly fitted. Where necessary, replace the water inlet mixer where needed.

F13 error code – Water Intake Fault: Heater Pressure Switch

Fault code F13 is displayed as water intake fault F13. A 2-minute long buzzer is activated after 2 to 4 minutes. This error code is raised when the required number of pulses is not recorded by the machine within a specified amount of time. However, the error code records sooner if the chosen program begins with a water softener. You can correct this problem by inspecting and replacing the water inlet valve. You should also call a specialist to inspect the on-site water supply. Change the reed switch if necessary.

F14 error code – Water Intake Fault: Heater Pressure Switch

Fault code F14 is caused by a defective heater pressure switch B1/13, the presence of foreign matter in the heater pressure switch, and a non-functioning circulation pump. To correct these defects, you need to replace the heater pressure switch. Inspect the wiring harness and the connection plug. It would be best if you also inspected the circulation pump capacitor. Replace the circulation pump if necessary.

F18 error code – Flow Meter Stationary State Monitor B3/4

Fault code F18 is caused by a faulty water inlet valve. When the water inlet valve is open when it should not, error code F18 is triggered. Unexpected impulses are recorded from B3/4 flow meter are detected as water flows into the washer. Inspect the water inlet valve for defects and replace it if necessary. It would help if you also replaced the water inlet mixer to correct this problem.

On a normal occasion, the water inlet valve component opens and closes to control the flow of water in the washing machine. However, it can also break down. When this happens, the water inlet valve is open when it shouldn’t be and this can cause the washing machine to show error code F11 on its digital display.

You need to follow specific steps to fix this issue. Follow this procedure to fix the problem:

  1. Remove and disassemble your washing machine’s electromagnetic part
  2. Inspect it for garbage. If you find any, you need to get rid of it
  3. Use a multimeter to measure the contact resistance of the inlet valve
  4. If there is no continuity, you need to replace the valve with a properly functioning unit

F19 error code – Flow Meter B3/4 Stiff and not Turning Freely

Fault code F19 is raised when there is a problem with the flow meter. To correct this fault, you need to replace the water inlet valve.

Warning: Disconnect power before replacing the CCU. Failure to do so can result in death or electrical shock. Unplug the washer or disconnect power.

  1. Unplug the washer or disconnect power.
  2. Turn off the water supply to the washer.
  3. Remove the top cover from the washer.
  4. Remove the connection block from the water inlet valve. You’ll also need to remove two hoses from the valve and this can be done using pliers.
  5. Remove the valve. It’ll be clipped under the main chassis of the washing machine. Get your screwdriver and push forward on it from the back – then use your hand to lever it out.
  6. Do the reverse of what you have already done to install the new water inlet valve.

F24 error code – Heater Relay Contact

Fault code F24 is displayed when the heater relay contacts fuse together or when there is water in the heater relay. Correct this problem by replacing the heater relay.

F25 error code – Desired Temperature Fault

This problem is caused by a defective heater relay. It is also caused by excess rinse dispensed or the amount of detergent or excess foam formation. Correct this problem by inspecting the dispensed amounts of rinse aid and detergent.

Since it’s likely that the heater relay is defective, you should check for faults in the plug on the output side of the heater relay. There may also be corrosion or contamination on the plug of the heater wiring harness. This can cause a gap between the contacts and this can reduce the transfer resistance causing this error to show up.
When the heater relay is defective, it can cause prevent rinse aid from dispensing. When your washing machine is heating up and the desired temperature hasn’t been reached within 75 minutes, it means that the heater relay is not active. During this, no-rinse aid will be dispensed.
When the error code F25 shows, an excess quantity of detergent or rinse aid has been dispensed and excess foam has developed. This foam can cause a drop in water flow pressure, directly affecting the heater pressure switch. To fix this problem, check how much rinse aid or detergent was dispensed then clean it out.

F26 error code – Boiling Protection

Fault code F26 displays when the temperature at the NTC sensor rises beyond 194°F. It can also be caused when the NTC temperature sensor relays the wrong information. Inspect the heater relay and the NTC sensor. Replace if necessary.

F40 – Electronic Fault

This error is caused by an electronic fault, such as damaged hardware. Correct this fault by replacing the defective electronic hardware.
