I have a dishwasher where the main pump doesn't always start.
Any ideas? Is there a recommended lubricant? Would a new seal solve any
problem?

maybe a faulty capacitor for the induction motor driven pump

The pump out motors are usually shaded pole motors, and don't have
a capacitor.

The OP said main pump not drain pump !

OK, so I can't read...
