Hotpoint 9518P drum motor not turning, fault not conclusively identified

The problem

An old Hotpoint 9518P washing machine would not turn the drum motor. The timer advanced and clicked normally, and the pump motor still operated, but the main motor did not run.

Likely cause

The discussion most strongly suggests either a faulty controller/PCB or a motor fault, but this was not conclusively proved. A broken internal wire or connection also could not be ruled out.

What fixed it

The accepted advice was that the user had checked most practical items already and that any further action would involve substituting parts such as the PCB/controller or motor, which was not recommended as guesswork. The original poster decided to start with the controller, but no confirmed repair result was posted. Professional diagnosis or a fixed-price manufacturer repair was suggested as a safer option than gambling on expensive parts.

Checks to try

• Motor brushes checked and said not worn out
• Brush contacts on motor commutator/inner coil visually checked with no visible damage
• Motor coil resistance measured at about 3 ohms outer and 4 ohms inner including brushes
• Connecting cable tested with a multimeter and appeared OK
• Controller output measured at about 40V AC to the inner coil and 26V AC to the outer coil
• Controller noted as a reconditioned unit fitted earlier that summer
