hi
unfortunately the programmer is faulty

Hi.

When that happens it is often because the drum bearing is starting to go. The first symptom is a loud high pitched noise during the spin part of the cycle. As problem gets worsening you will notice that the drum will be a bit wobbly if you spin it by hand.

Here parts and diagrams.

Hi,

Problems with a washing machine not spinning or not draining are often inter related..

If you are having a problem with your top load washer then check out this tip...

Press and hold 'dry' & 'spin' that should unlock OR Try holding the "end of cycle" button down for 5 seconds.

Clean Out your Water pump filter if that is not dirty replace the water pump. f02 is Code for LD Long Drain something is clogging your water drain in the washer or your kids rock or pen got stuck and chewed up the blades on the water pump

"F02" is a Long Drain error code. This is an indication that you may have an obstruction somewhere in the drainage system somewhere. The washer will NOT complete a cycle with the condition present that is causing the error code. In most cases this means there is a clog in the drain pump or inlet line running from the wash tub to the pump. There is a white screw off cap on the drain pump that you can remove to inspect the pump impeller and clean. The following link explains:

Included is a follow-on link that explains how to check the drain pump to clean. You may also have to remove the inlet hose that runs from the bottom of the wash tub to the inlet side of the drain pump. Debris and small articles of clothing can commonly clog in this area as well causing the drain cycle to fail.

NOTE: The "SUD" error code can often occur in conjunction with the "F02" error code. This is due to air being detected in the drainage system, which can occur if the pump is not running, or if you have an obstruction BEFORE the pump. You need to remove the inlet hose from the pump to ensure it is also not blocked. Correct your drainage system fault, and the SUD error should go away.

If you have any questions about this repair, or need additional assistance, please let me know. I hope this helps you.

NOTE: If these preliminary measures do not correct your problem, you may have to replace the drain pump. It does not take much to damage the pump impeller or motor. Since the error code is generated if the drain cycle exceeds 8 minutes, if the pump is damaged and can't pump at the required volume, the error code will continue to appear until the pump is replaced.

Press 'drain' & 'spin' together for 3 seconds to see if it clears. This is your control panel lock.
If not cleared unplug the washer & wait for 30 minutes for the CCU (computer) to reset.

If helped you can rate.

The door will stay locked if the machine did not drain properly. Try running a Drain & Spin cycle.
