I have Fridgidaire dishwasher model # PLD8998CC0. All of sudden the door stopped latching closed. The latch seems to start latching but it is not completely locked so the door can be pulled open without pressing on the latch. I am guessing something is stuck or debris got in but broken parts are possibility. I wonder what is the proper way to remove the cover on this dishwasher to get access to the latch? Can anyone point me to repair manual for this appliance? I already sprayed some WD40 onto the latch to see if it starts working again but no luck so far.
