Check the drain for a blockage.

when you start a cycle, your machine should drain for 30 sec, fill with water, and then the circulation pump should come on. your water level should be up to the handle on the filter in the bottom. if you drain, and fill to the handle and then the intake drain error comes on, your circulation pump is stuck. if it does not fill to the handle, you may have a problem with the inlet valve.

Hi

Intake/Drain light flashing means an issue while draining. The dishwasher is not draining properly. Please check for air gap on the dishwasher is not clogged. It prevents dishwasher from draining properly and sometimes the drain flow is restricted due to gunk. Cleaning or bypassing the air gap will resolve the issue. If this doesn't resolve the issue then it is due to seized (or stuck) drain pump. Keep handy large bowls and towels to soak the water out. Disconnect the power to the dishwasher or turn off the breaker to the dishwasher. Tip machine on its back; remove screws that hold the bottom tray on. Remove the hoses to the main motor, remove electrical connections and switch it on. If the error still appears then turn the rotary selector switch to "Stop/End" or press the "Start/Stop" switch for approx. 5 secs to cancel the error message. Switch the appliance off and then back on again. Hope this helps...please post back for further assistance.

The manual is available here: http://www.miele.ca/miele/canada/OperatingInstructions/manuals.asp?ParFolder=Dishwashers&SubFolder=Previous%20models . Scroll down through the list to the G643 G843 Incognito. The maintenance items listed below are detailed on page 44 and beyond of the manual.

The Intake light is also the Drain error light. If the light is flashing, then turn off the dishwasher and clean the triple filter, the drain pump and the non return valve and make sure that there are no kinks in the drain hose.

Make sure the water is ccoming in at a pressure above 4.5 psi. Also make sure that the water valve is open and clean the water intake filter.

The final possibility is that the Waterproof system has tripped and you need a Miele technician to service the unit.

I hope this helps.

Does it fault out in the beginning, middle or end?

Hi,
F13 is an inlet fault.
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.

Hi,

the inlet/drain light is a standard fault light and can mean anything without connecting the Miele dianostic software to the unit. This is only available to Miele service techs or service agents. If the light comes on in the first minute then it is probably a drain fault. Try checking the drain spigot at the sink end where the drain hose connects as these are usually the cause of most dishwasher faults.Hope this helps

hi,

try checking the spigot under the sink as quite often the hole has not been opened up enough and there is a shoulder for food to jam up against causing a blockage. Remove the drain hose and have a look in the hole of the u bend.

If ok remove the filter in the base of the unit and remove the non return valve and make sure the drain pump can turn and there is not anything blocking it.

My Miele Incognito dishwasher kept getting an error with intake/drain light. The light flashed 5 times. Phoned Miele Technical Support to investigate the problem. The problem is that a seal in the bottom of the dishwasher has failed and there was water in the motor pan. Currently, $175 service charge for the technician to come look at it.

I don't want to spend $175+ to have them replace a 75 cent rubber gasket that I could replace on my own.
