If flooding the print module means flow of melt up into the module when the nozzle has been obstructed by the model detaching from the base plate, then I have had this happen several times. The first time I removed PLA from inside the module. To do this I needed to heat the nozzle to melt blocking PLA. I tried this the second time, but a small spark occurred between tweezers and module; the module was no longer recognised. I bought a new module. The third time, to the new module, I heated the nozzle and brought it close to the heated bed, then moved to nozzle up to get some space, switched off and removed the softened/melted PLA. I replaced the bed to get better adhesion of models, and so far the problem has not occurred. This is a long answer to your query, but an instant short circuit caused failure of the module. My electronic expertise was not up to checking failed part and rebuilding module.
