Can't remove the screw retaining the plastic wash Impeller seems extra tight. It appears that the motor shaft slips and grabs which indicates slippage. So far have not been able to resolve this issue and would appreciate a solution.
Answer Hello Joseph. If the motor shaft is slipping, and you have it locked down, that would indicate the motor is bad and will need to be replaced. Some of these screws can be extremely tight and hard to remove. Try using some rust buster TJ93241 on the screw.
