Optima G2430 Miele dishwasher with intake/drain flashing light

Please check that the water supply valve is open.

The intake light blinking error can be caused by several different problems and may take some pains taking effort to figure it out. There is some helpful information about Intake/Drain light flashing. http://www.techanswerslive.com/appliances/miele-icognito-dishwasher-service-mode-error-codes/12

F13 Indicates that you have a water intake fault. The machine is not receiving the the proper amount of water quantity. You could turn off the water supply and disconnect the water inlet hose. There is a filter inside, to remove the filter you have to take out the seal and then you could use a pair of needle nose pliers to take out the filter basket. If the filter is clean you and your water supply is good, you have a problem with your flow meter not registering pulses when the water is taken in.

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.

Hi Jennyglopez..I do not think your pump is the issue,however you can make this checks.1-Take the filter combination out of the wash cabinet 2-Scoop the water out of the cabinet using a suitable container 3-Press the catch for the non-return valve inwards 4-Lift out the non-return valve and rinse well under running water.5-Remove all foreign objects from then on-return valve and drain pump 6-Carefully replace the non-return valve and secure it with the catch.Ensure that the catch engages correctly.You can also check drain hose &remove any kink in the drainhose.where the drain hose engages under the sink sometime gets clogged.Disengage the pipe & make sure hole in the drainage not clogged.Thanks & goodluck

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.

Usually indicates a intake or drain fault - could be a plugged drain line at the garbage disposal or insufficient water coming into the unit

When this happens with my dishwasher it usually means that the drain is clogged with food/debris.  To fix 1) remove bottom dish rack from machine 2) using a small cup, scoop out as much water as possible 3) remove inlet drain cover and unsnap the plastic insert and remove 4) rinse the plastic part and reinstall 5) start machine 6) if light still flashes, repeat steps 3 4 and 5 and restart

The intake/drain light blinks. How do I fix this problem?

this can happen after inactivity. the circulation pump seal sticks and wont turn . when the dishwasher starts to fill the circulation pump is pulsed on to see if the preasure switch switches over (to see if water is getting into the dishwasher) if the pump does not turn there is no preasure and the machine stops thinking no water has entered. turn pump by hand to cure.
