Assess the causeFollow the evidence.
Inspect drum support, bearings, seals, foreign-object interference and model-specific tub construction.
The exact model and operating conditions determine which tests apply. These are possible inspection directions, not a list of components that must be changed.
Before the appointmentKeep the useful details.
Describe whether the drum feels loose when the machine is off; do not dismantle the cabinet.
Record the timing, previous work and accessible model label. Do not remove covers or handle live, refrigerant or pressurised components to obtain information.
