4 year old hard working Bosch dishwasher will not drain correctly. This occurs in both quick and full wash cycles. We checked drain hoses-they are OK. We checked the common drain used for both the DW and Kitchen sinks-they are OK. We discovered that the water will eventually drain if "cancel drain" is selected 2-4 times. A slow trickle can be seen in the drainage tubing which sits under the kitchen floor and above the family room tile. We found some information on the IT to test the controls by pressing power wash and wash at the same time. the numbers that appear are: C2, PO, EO.
Thanks in advance of any direction
