I have a GE Profile dishwasher, PDW7800, that fills, drains, etc. but will not spray. However, if I use the Triton XL Service Mode each of the functions; drain pump, detergent module activation, main pump (which does spray water on the dishes), water valve activation, open/close active vent, and status LEDs all work or at least seem to be working. (The heating element did turn on while in the service mode but did not turn off after the indicated time in the matrix).
Does anyone have ideas on why the main pump is not being activated during normal washer usage? Is the MODULE CONTROL ASM the part that controls the washing cycles?

Yep it is the moduel
