Machine appears to have had a flood fault,have removed water from overfill tray but pump contiues to run.Micro switch for flood level operates and tests ok. Is there another switch which indictes overfill inside cabinet that may cause pump to run continually?
L2 flashes and unit will not step on in program,have carried out a reset with no success,pump continues to run and L2 flashes. Is there a site where I can get a copy of the schematic diagram for this model.
Micro switch was actually faulty,moisture had entered the switch and caused internal tracking and shorting out the micro switch ,making the pump run continually as it thought it was still in flood mode.
Flood appears to have been caused by a pin hole in the water fill hose in the base of the dishwasher,causing water to spray on the micro switch and eventually biuld up in the base of the machine.

There is a slight leak somewhere or the machine keeps overfilling causing the drain pan to activate via the flood switch.
remove all dish trays from washer, unscrew and remove lid off salt softener, almost and thoroughly remove as much excess water as you can, it could be the vacuum switch/water level float.. do the tip over again, and be sure you get it all,
replace all trays and softner lid and machine should work again.
I believe the washer has had a flood type situation.there is normally a flood switch in the very bottom of the dishwasher right at the very floor,if water get into the bottom tray it floats a piece polystyrene foam wich triggers a little micro switch wich will run the pump continually & show Overfilling fault at the same time..The water in the tray needs to be mopped out with a rag or spunge so that the styrene foam can drop back down.The blockage you had may have caused this flood situation some how.The overfill fault was probably due to the washer not pumping out,So that may be ok now that you have cleared the blockage.hope this helped.
Note: Lights blinking, pump running and controls dead indicates an over fill fault
1. Disconnect the power to the unit
2. Remove the lower access panels and check the tray under the dishwasher (you will probably find that it is full of water)
3. Use a towel or a sponge to remove the water
4. There is a float that should stop the operation of the dishwasher and run the pump if water is in this tray. Check this pump to see if it is functional
5. Test the dishwasher
6. If there are no leaks from the dishwasher into the pan, check the drain hose under the sink
7. The drain hose must run up to the top of the underside of the counter top then down to the drain. (If the hose is not set up like this, water from the sink drain will flow into the dishwasher and overfill the tray
The dishwasher drain hose may be clogged. When the dishwashr starts up can you hear the water running into the Sink faucet drain. If not inspect the hose that attaches to the Sink Drain for restrictions. Also in the bottom of the dishwasher you should have a filter. If this filter is clogged you cannot expel water. Clean the filter.
