Assess the causeFollow the evidence.
Assess bearing condition, shaft, seal and tub construction before choosing a repair route.
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.
Mention any rust-coloured marks or rumble that increases with spin speed.
Record the timing, previous work and accessible model label. Do not remove covers or handle live, refrigerant or pressurised components to obtain information.
