F70 fault error keeps appearing on my Miele G1220SC full dishwasher - any idea?

dont know --notify manufacturer and have ready where and when bought

Need a model number - however F70 usually refers to water entering the drip tray on the bottom of the unit - this activates the float switch and causes the machine to cease all actions - and start the drain pump to evacuate the water

F70 means that water is in the bottom tray of the Dishwasher - this could be for several reasons - Ranging from using to much soap to a faulty seal. Most Mieles have a panel at the toe kick that can be opened to extract the water and allow the unit to dry out - remove the toe kick and look for the panel in the center of the unit - two T20 Screws securing it

F70 means there is water n the drain pan under the under - ussually indicating a leak somewhere in the system - could be a faulty seal at the door or a hose inside that has a pin hole leak

The reason the pump keeps running when F70 fualt appears is that the water leak circuit has tripped which causes the dishwasher controller to empty the dishwasher to avoid flooding of the motor and pump area.

The sources of leaks could be many, to start with hoses and water inlet valve. If you feel you can handle such repairs then go ahead otherwise call a technician.

Make sure the mains power is turned off when you are working with the dishwasher internals.

There are two screws that hold the plate in. Because they are recessed, you may not think they are the right screws. Look at this video for a step by step.

hello,

The code is an indication of a problem on the washer

F67 means the input voltage on the microprocessor is incorrect. Code F70 indicates a problem with the water temperature sensor circuit. F76 means the NTC temperature for the cold water valve is over the limits.

thanks.

Hi,

Yes. F70 is a flood in the base of the unit which activates the float switch and constantly activates the drain pump until the water has gone. Isolate the unit at the power switch and remove the bottom panel under the door panel. Dry up the water as best possible with a towel. You will see the float at the front. Run the unit again and check for any water leaks. You may just have over sudded the unit with too much detergent. Only use 2 teaspoons of powder. To start with while testing don't use any detergent. Good luck

Hope this helps.
