Thread: Another GE Profile drain issue

I have a Profile Triton Model # GSD5360F00SS that will not drain. I have read the previous post concerning probable causes. My unit has 1 1/2" - 2" of water remaining in the DW following a cycle. I watched as it drained into the sink but not all water was removed (Sunday) on Monday I could not get the dw to drain at all. The solenoid appears does engage but no water is pumped from the dw. I "jumped" the drain boost pump and the system works as advertised. When i run the rinse only cycle with a meter on the leads to the boost pump it only gets power for about 2 seconds(very end of cycle) then power is removed. Is this a control panel issue or timer issue????

This is what I have done so far:

1. removed and cleaned all screens
2. replaced the plunger (not visibly damaged but I observed it allowing some back flow)
3. inspected the flapper
4. checked for clogged lines

Any help is appreciated
