Ultimate Guide to Solving Miele Dishwasher Error Code F24

Check the Water Supply and Hoses

The F24 error usually appears when the dishwasher detects a problem with the water flow. First, make sure the water supply is turned on fully. Sometimes the valve connected to the dishwasher is partially closed or blocked, which can stop water from entering the machine. Inspect the hoses for any kinks or bends. Even a small twist can prevent proper water flow and trigger the error.

Next, remove the hoses and check them for blockages. Sediment or dirt can accumulate inside and reduce the flow of water. Use a flashlight to look carefully and clean out any visible debris. After cleaning, reconnect the hoses tightly to avoid leaks. Also, ensure the hose filter is not clogged, because this can restrict water entering the dishwasher.

It’s important to check the water pressure as well. Low pressure can sometimes cause the F24 error. You can test it by running water elsewhere in your house to ensure the supply is strong. If you notice weak water flow, contact a plumber or check your home’s main water valve.

Finally, always ensure the dishwasher is properly positioned. If it is tilted or uneven, it can affect water intake. Make adjustments so the machine sits flat and stable. This simple check can save a lot of headaches.

• Turn on the water supply fully
• Inspect hoses for kinks or bends
• Remove and clean hoses for blockages
• Check hose filters for dirt
• Test water pressure in the house
• Ensure dishwasher is level and stable

Inspect and Clean the Filters

Dirty filters are a common cause of the F24 error. Over time, food particles and soap residue can clog the filters. Start by opening the bottom of the dishwasher and removing the filter system. Check both the coarse and fine filters. Rinse them under running water to remove visible debris.

For stubborn residue, use a soft brush to gently scrub the filter. Avoid metal brushes because they can damage the mesh. Make sure every corner is clean, as even a small particle can restrict water flow. After cleaning, place the filters back carefully. Ensure they click into place properly.

Filters should also be checked for damage. Cracks or tears can allow debris to bypass the filter and block other parts of the dishwasher. Replace damaged filters with genuine Miele parts to maintain performance. Regular cleaning of filters can prevent many future problems, including the F24 error.

Also, clean the filter housing and surrounding areas. Residue can build up in corners and reduce the effectiveness of your filters. Wipe it down with a damp cloth and mild soap. This step may seem small but is very effective.

• Remove both coarse and fine filters
• Rinse thoroughly under running water
• Scrub gently with a soft brush
• Check for cracks or damage
• Clean the filter housing area

Examine the Water Inlet Valve

The water inlet valve controls water entering the dishwasher. If it is blocked or faulty, the F24 error will appear. First, unplug the dishwasher and turn off the water supply. This ensures safety before handling any electrical parts. Locate the water inlet valve at the back or bottom of the machine.

Check the valve screen for dirt or mineral deposits. Clean it carefully using a soft brush or cloth. If the screen is damaged or the valve itself shows corrosion, it needs to be replaced. Do not attempt to use the dishwasher with a faulty valve because it may lead to more serious damage.

You should also check the electrical connection to the valve. Loose or corroded wires can prevent the valve from functioning correctly. Tighten connections and remove any corrosion with a soft cloth. After everything is checked, reconnect the valve, restore the water supply, and test the dishwasher.

Pay attention to how the dishwasher fills after repairing the valve. If the F24 error returns, further inspection may be needed by a professional. However, in many cases, cleaning or replacing the valve solves the problem completely.

• Turn off dishwasher and water supply
• Locate water inlet valve
• Clean valve screen of dirt and deposits
• Check for corrosion or damage
• Inspect and secure electrical connections

Clear the Drainage System

A blocked drainage system can also trigger the F24 error. First, check the dishwasher’s drain hose for any clogs. Detach it from the sink or floor connection and look inside. Use a long flexible brush to remove debris. Even small obstructions can affect water flow significantly.

Next, inspect the dishwasher drain pump. Remove any trapped food or items that may be caught inside. Turn the pump manually to ensure it rotates freely. If it is stiff or jammed, cleaning may be necessary. Avoid using sharp objects that could damage the pump.

Check the sink drain connection as well. Sometimes, the blockage is outside the dishwasher. Pour water down the drain to see if it flows freely. If it is slow, unclogging the sink will improve dishwasher performance.

Finally, ensure the drain hose is correctly positioned. It should have a high loop or air gap to prevent backflow of water. Improper placement can confuse the dishwasher and trigger the F24 error.

• Check and clean drain hose
• Inspect drain pump for debris
• Turn pump to ensure it rotates freely
• Avoid damaging sharp tools
• Check sink drain for blockages
• Position hose with high loop or air gap

Reset the Dishwasher Electronics

Sometimes, the F24 error is caused by a temporary glitch in the electronics. Resetting the dishwasher can solve the problem quickly. Begin by turning off the dishwasher and unplugging it from the power source. Wait at least five minutes before turning it back on.

Some models have a built-in reset button or combination of buttons. Consult your Miele manual to perform a proper reset. Press the buttons as instructed and hold for the required time. This can clear minor electronic faults and restore normal operation.

Also, observe the dishwasher after resetting. Watch how it fills with water and starts the cycle. If the error disappears, it was likely a temporary electronic glitch. If it returns, further inspection of mechanical parts is necessary.

Resetting is a simple but effective way to fix minor problems without professional help. Doing it carefully can save time and prevent unnecessary repairs.

• Turn off and unplug dishwasher
