Question about Asko D1796FI Built-in Dishwasher
Hi Alan, The F2 on Asko means it's sensed an overfill, that in itself though can be provoked by a couple of thing's. First, check for blockage at the end of the drain hose where it connect's to your household plumbing, be it under the counter by the sink or wherever. Undo the hose and see if it drains freely into a bucket, if so the drain to that point is clear. Insure it is clear beyond and move forward. Next, If you turn the power off and then remove the kick plate/toe panel ( that in itself is tricky if you've never done it, I can try to explain if need be...let me know ) then with aid of a flashlight or equivalent, check the overfill basin for water. If water is present, this will initiate the over fill float switch directly behind the main line junction block, hence the F2. ( of course a basin full of water can be from a faulty pump too, but you'll know this if the unit wouldn't drain into a bucket ) Then you must find the cause or leak, check the rubber hose at the top of the motor to the tub and the hose from the sump to the motor...it's tricky unless you've looked many times like I have and know what to look for. I wish I could guide you better from afar. Also look for sign's of leaking to the fill valve assembly. Another possible reason to overfill, a clogged pressure switch hose. Right beside the float and overfill switch assembly ( in fact it is wired right to it ) you'll see to the right on the sump assembly will be a pressure switch and hose. The switch will be about 1.5" in diameter with a brown color body and 4 brown wires going to it. At the bottom of the pressure switch will be a skinny black hose, remove the hose and clean it out via blowing through it or other means, it often will get plugged with undesolved detergent, food or other debris. It just comes off with carefully directly pulling force. This is what tell's the unit when to fill and when not to fill, hence if it is clogged it will not fill. Once the leak is found or the problem found, use a large sponge to soak up the water from the basin and the dishwasher should be ready to go. Those are several thing's to look for before changing part's to try and solve your problem. Let me know if I can assist you further. Thank you for visiting "fixya" today. P.S. Having said all this, if you feel at all uncomfortable performing anything I've laid out, please call a qualified "Asko" authorized pro to come to your home for service. They usually aren't serviced by many appliance repair places, at least not proficiently in my providing factory warranty experience. Thank's again and good luck. macmarkus :)

Hi Alan, Its good you took the steps from the manual to try and solve this problem. I am assuming this machine does not run at all at this point? Anyway, it sounds to me that it is possible that the water pump could be bad or maybe just stuck. Sometimes debris can get around the impeller causing this problem, even though it was replaced 3 years ago. You would think it would last much longer, I would say.With the F2 message being displayed saying the tub has to much water we know is a false reading. Do you have excess to the float on this unit to see if it is possible it may be stuck in the full position? If this were happening it would give this code. I assume this is a 1996 model and I am not sure how the float and switch are set-up on this unit, but try and check to see if you can manually raise and lower it, you should be able to here a click as the set of contacts open and close when the unit is filling with water on its fill cycle. This may change the code of saying it is to full. I would also go to the breaker and turn it off for at least 5 minutes minimum, to see if it will reset this unit. I know there is power to the unit as the displays are on. If you try starting the unit, it will not start filling with water? If not, you can manually add water to the unit if you can see the float switch and, after the breaker trial is done first and doesn't take care of resetting of you're machine, you can try this and stop adding water when you hear the float switch contact click. I would then turn the unit to the pump out cycle to see if the pump is energized to pump out the water.This will tell you if the pump is good or bad. I believe that the pump is good and you are getting false signals for one reason or another. Anyway Alan, try and check the things I have asked of you and get back to me on this. I would like to continue to help you solve this problem, but I will be gone from 7:15 am and return home at around 12:30 pm this morning. I am a contractor and have a service call scheduled for this time:( It is now 7:00 am here in Ca. I will return and check to see if you have gotten back to me on this.

Hi and welcome to FixYa. I am Kelly.
Inside your machine there is either a water level float or a sensor.
This is the FLOAT for yor machine located in bottom of the tub. Usually when you get an F2 error this float is stuck in the up position or there is debris preventing it from lowering.
Once you clear everything as you gently lift it up and down you should hear a CLICK.
If you hear the click(s)..... and it still shows F2 then the Float switch underneath the tub has failed.
If you need anything more just repsond here.

Yes its the fault in the drain pump.
either the drain pump is got worn out or its getting blocked .the drain pump needs replacement .the machine is not detecting the drain pump.its either got loose.
many times removing the pump and cleaning it then again refitting solves the problem bit if that does not helps then the drain pump needs replacement.
can get required parts from www.repairclinic.com
This will help. Thanks please keep updated.please do rate the solution positively .thank you for using fixya

Take the outer door panel off and check for broken wires in the loom,
running down from the control circuit at the top of the door. There
should be a wiring diagram inside the door, this will tell you where to
check on the programmer to test the resistance of the circ pump.
Either that, or check the pump by removing the toe panel at the bottom of the unit, The circ pump is the big one at the back.
Check for leaks in the base. remove plug from wall and remove both the kick and service panels, get a torch and switch 'er back on. Run it through a cycle.
