I have a 9 year old front load washer Model # GHW9100LQ. It displayed F02 and I have cleaned the all hoses and the connection plus the filter. They were all very dirt even though we have been using high efficinecy detergent. This still didn't solve the problem and I still get the F02 code, the pump seems to be working .The pump got hot when the washer started to spin fast during the drain/spin cycle and the last minute of the cycle lasted over 10minutes and then the SUD code dispalyed.

SOURCE: Not spinning, and buzzing sound

F02 is the code for long drain. The first thing to do is check the pump filter. Remove the lower panel by removing the 3 torq screws, the panel will come off. Right in front will be the pump filter. Remove the cap and pull the filter out. Clean out any lint and/or debris. See that you have some low basin to collect water, or some towels when the filter is opened. Or take the rear drain tube from the wall drain and lower it to basin or bucket. (The drain pipe must be fitted back in the SAME position) The spin will not work when your filter or pump is blocked.

SOURCE: Persistent F02 / SUD error. Tried all the tricks!

how about the line from pump to bottom of tank?not excess suds?might be bad control bd..f code is generated when control bd senses incorrect current draw by drain motor ..could be glitch in readings or a misread

SOURCE: UL Code

Solved the unbalanced problem - open the top of the machine (press in with a flat putty knife about 3" in on the front on each side while lifting up as there are 2- 1" wide catches). Once both sides are unlatched, raise the lid then slightly lift the rear of the lid so that it fits into the curved part at the top of the hinges then open all the way - tape the lid to the top so it doesn't flap about and scotch the lid to keep it from falling back down on you. Now, look around - see all that rust?  The rust has fallen into and gotten underneath one or more of the 4 white plastic suspension "ball joints" which have probably totally dried out by now from their factory grease because of the water, bleach, and rust particles.  Having someone help you, simply lift up on one of the 4 corner suspension rods - gravity and weight is all that holds them down. The white ball will lift out of the socket and still be attached to the rod. Clean out the rust, lightly sand the "socket" with emery cloth, then slop in a fingerful of grease. I used automotive wheel bearing grease with graphite in it. Also scrub off all embedded rust on the white plastic ball. Lower that corner back into the newly cleaned and greased socket and repeat for the other 3 corners. Now when you move the tub around notice how the balls pivot in their sockets like they are supposed to. When they were dry and rusty they wouldn't move enough to allow the tub to twist like it should so it slammed around.  Now, shake your head in disgust that after only 2 years there is so much rust that you wonder if it will make it another year before falling apart, close the lid, and try another load.  That totally solved my off-balance problem where even a single handkerchief would give the UL error. It is still a finicky machine, but at least once again works like it did when new.

SOURCE: What does the "sud" message mean?

hello fo2 means if the drain time exceeds 8 minutes the water valves are turned off and f/02 flashes. things to check / check the drain hose for any kinks and blockages check the electrical connection to the pump make sure the pump is running / check the drain pump filter make sure its not block if these do not sort the problem replace the pump. to clear the display press pause and cancel to clear good luck
