LG dishwasher, im stumped
« on: September 05, 2013, 08:51:40 PM »

Model LDF88125T. Looks like its a Bosch.. Customer says another company was out, had some burnt wires... Ok thats obvious, the guy fixed it, did a good job IMO. Now the complaint is, it sometimes works sometimes doesn't and the customer gets a PF code on the display. During the wash, when i open the door, the machine isn't stopping. Ive seen this on the Bosch, simple easy money latch assembly, just for the heck of it, i tested the micro switches, and they are fine, heater switch is working, motor switch is working, nice strong clicks, nothing burnt, NC/NO where it should be. There is a simple little schematic on the kick plate, but its so gunked up i can't read it. Has anyone seen this? I have a new PCB on order, but i cant believe it's not the latch. Why would you have a door switch if the board is wired in parallel to the switch? It's making me second guess myself. Does anyone have a decent schematic for this machine?

Just added the service manual to our google drive. Maybe you will find it helpful.

Replace the wire harness.  Something is bypassing the latch switch.
