Question about Miele Dishwashers

1 Answer

Hello, Can you please tell me what "waterproof system has activated" means. My dishwasher has alarmed to indicate the water supply needed to be turned off along with the message F70. The water has been turned off but the machine kept running even though the machine had been turned off at the panel and so the power supply was also shut off. How do we solve the problem? Thank you, Angela

Float switch fault
Cause:
Water in the drip pan. Changeover contact of overflow float switc

Remedy:
1. Remove the water from the drip pan (e.g., with an absorbent cloth).
Note:
Upon opening the appliance and removing all water, there should be no
smudges, smears or traces of deposits.(rust, calcium, detergent, or salt?).
2. Check all hoses, connections and threaded unions for leaks.
Note:
If the leak source has not yet been detected, check the following areas
in the toekick and the drip pan for wear and tear:
�� Connection between the circulation pump and the sump
�� Axial face seal of the circulation pump
�� Connection between the drain pump and the sump
�� Connection between the salt container and the water intake
�� Connection between the water intake and the cabinet side wall
�� Overflow (e.g., excess foam formation)
�� Water level between the overflows (�� seating of the lower door seal?)
�� Connection between the cabinet and the salt container
�� Non-return valve in the sump (�� water running back from the drain hose?

I have a Miele W 2389. Message saying waterproof system has activated. Turn off stop ****. What does it mean?


Hi Dear. Seems like your machine had internal leak. Float switch has been activated. That triggers error message on the display. What you can do is: Tilt the machine 45 degree (Back or forward which ever easy for you) wait for leaked water come out underneath the machine. If water comes out of machine, it's a indication of one of the plastic component failed(it could be drain hose- tub to pin trap hose- may be inlet valve etc....) If there is no water coming out of machine, float switch may be malfunctioning. In that cases you need to contact Miele center to get help.Thanks.

When attempting to start dishwasher load the signal F 70 come up and it wont work. Purchased 2nd Jan 2008.


F70, waterproof system activated. this means you have water in the bottom pan of the dishwasher. your miele shuts itself off and runs the drain pump continuously any time water leaking is detected. you can pull out the black plastic toe kick under the door. there is a cover panel in the center held on with two t20 screws. you can dry up the water and try to run a cycle. if it works ok, cut back on your detergent by 1/2. if it leaks again, you should probably request service from miele. if you want to try to repair it yourself, let me know and I will help you troubleshoot it further.

What does the fault F70 mean for a Miele G 1534 Sci dishwasher, please?


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.

My miele dishwasher shows intake/drain light flashes, it seems to me that drain works but no water goes into the dishwasher


hi, firstly check the filter in the waterproof system where the tap is to make sure it is not blocked. turn off the water and remove the connection with the white box attached this is the waterproof system. remove the black seal and you will see the filter. pull it out with a pair of pliers and clean it.

if this is ok check to see if you have a restrictor on the tap or inside the tap and also make sure water is flowing from the tap prior to reconnecting the waterproof system.
run the unit again and when it is time for the machine to call for water you can manually fill it and see if it works using a saucepan or bucket. if this works ok you may have a stuck waterproof system and probably need to replace this.
Hope this helps

I have a Miele Deluxe G590, no water getting into machine


Hi, the most likely cause is the waterproof system faulty. Which is the large grey box connected to your water supply.It's basically two water valves in series. The appliance is timed fill, if you increase the fill time this might help.The details can be found in the instruction book.Also disconnect water proof system and check water pressure.

Miele dishwasher doesn't work.error F70


When this problem happened to our machine, it was simply the pipes under the sink where the dishwasher drain pipe fits were blocked with muck. This was preventing the one way valve connecting the drain hose to the household waste from fully opening thus preventing the machine complete its drain cycle.
Solution was to thoroughly clean the sink drain pipes - plunger, power plunger and then a dose of chemical cleaner. Dishwasher is as right as rain now:)

Our MIELE TURBOTHERMIC shows a red indicator light on the topic of: drain/watersupply.when switched off and restarted, it evacuates the water succesfully and commences the cycle but then after two minutes,...


Hi,

First the unit drains and then fills with water. When the unit has intially drained open the door and manually fill the unit with water, about 5lts. This will then allow the dishwasher to go to the next step which is to circulate the water. If this works ok then the water tap is defective, water inlet valve is defective or the electronic unit is not sending the signal to activate the valve. The water inlet valve is the white square box attached to the tap. Remove this and check the filter and make sure water comes out of the tap.If ok then remove the bottom panel of the unit under the door. On the right hand side there is a 2 core cable with a male and female connector. Unplug this and check for voltage from the electronic when the unit goes to fill with water. If there is 240v then the electronic is ok. You will then need a new waterproof system from Miele.

F1 coming up on screen


You must be having F1 code flashing on door display of one of the drawers of your dishwasher.

This means the flood switch has been activated. Check if there is water inside the dishwasher (turn power off at the mains supply to your dishwasher).

If water is there then empty with a small container and try to run the dishwasher again (turn power on first). If the problem repeats, then you may not be able to do much but call the technician. The water level sensor that tells the dishwasher to stop taking water might have failed.

Try to clean the filter plate and drain filter if you have not done it for a while.The user guide tells you how to do this.

Good Luck

MIele waterproof system reacted


That means that there is a leak that passed throught the waterproof system, and the water protection system had reacted putting the machine on error mode, as the water can damage electric parts, and cause serious hazard.

Sometimes you can reset the error by unplugging power cord, however you should call immediately a technician, as using the appliance when there is a problem with the waterproof system, you can be seriously injured by electric shock.

there is still water in the waterproof tray at the bottom of the machine and the float switch has activated. pull the machine out (if pipes allow) and tip the machine backwards to drain the water from the tray.
