Keep getting a flashing lid-lock, which essentially causes machine to pause during the different cycles- usually appears when washer begins to spin. It can be bypassed by waiting until light turns off, hitting pause and unpause, which seems to resume machine. However, this is a lengthy process and clothes don't appear to be washed and are still wet after final spin. We have replaced the shift actuator and the lid lock. I have also heard a slight squeaking noise when in wash mode w/aggitation that's intermittent. It sounds as if washer is aggitating and spinning at some points. Please help. Error codes are F421 in fault codes and F8421.
