Miele Dishwasher Error Code F70

hen your Miele dishwasher displays Error Code F70, it’s indicating a problem with the float switch. The float switch plays a crucial role in determining whether there’s enough water in the dishwasher’s tub once the allotted filling time has passed. If it’s damaged or malfunctioning, your dishwasher may continue to fill with water when the issue should have been detected and resolved.

Here are some solutions to address Error Code F70 and get your Miele dishwasher back to its optimal performance:

Solution #1: Check the Drain Pump

A faulty drain pump can often contribute to false float switch errors. When the drain pump is not effectively removing water from the dishwasher’s tub before the next fill cycle, it can create the appearance of an issue with the float switch.

To tackle this:

• Inspect the drain pump for any visible damage or obstructions.
• Ensure that the drain pump is functioning correctly. If it’s not, it may need to be repaired or replaced by a qualified technician.

Solution #2: Examine the Float Switch

Checking and potentially fixing the float switch is another crucial step in resolving Error Code F70. However, accessing the float switch usually requires partial disassembly of the dishwasher.

Here’s how to proceed:

• Turn off the dishwasher and disconnect it from the power supply to ensure safety during the inspection.
• Carefully remove the lower front panel or any obstructing parts to access the float switch.
• Inspect the float switch for any visible damage, corrosion, or debris. Clean the float switch if necessary.
• Reassemble the dishwasher, ensuring all parts are securely in place.
• Restore power to the dishwasher and run a test cycle to verify if the Error Code F70 has been resolved.

While these solutions may help address the float switch error, it’s essential to exercise caution during any DIY repairs and, if needed, seek professional assistance.
