Kodak recommends the following cleaning solution for processing
equipment.
Sodium sulfite (anhydrous) ............. 15 g
Sodium carbonate (anhydrous) ........... 15 g
Calgon* ................................ 2 g
Water .................................. 1 l
* Sodium hexametaphosphate
The solution should be allowed to remain in the equipment overnight
followed by a thorough rinse. It is non-corrosive and will not harm
metals or plastics. It will remove traces of hypo and other chemicals.
Actual proportions are not critical and the formula can be scaled up for
any size equipment.

If the machine were mine, I'd run some water in it for several days at
temp to help make sure that the pumps, lines and switches were all
running smoothly. After that much time sitting, the strangest things can
happen. Water is much less likely to give you fits if you have leaks,
etc from pumps and tank seats.
I have not seen that machine, but did you make sure that ALL the bleach
was drained from the machine? Good luck.
