Before you call
Safe checks you can make
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
With power disconnected, check only for an obvious item physically blocking a user-accessible moving part.
Do not keep forcing repeated starts if the motor hums, stalls, overheats, or trips power.
Wipe the control surface dry if moisture or residue could be affecting touch inputs.
Reduce or redistribute the load if the fault appeared during spin/tumble and the appliance is not leaking or mechanically jammed.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
