There is a small Black threaded cap located on the Bottom portion of the motor. This is your drain plug. There should be 2, one is a little higher which is your Oil fill plug (usually Yellow or Red), the lower one which is on the opposite side should be your drain plug. Could also be a square head screw located at the bottom of the motor that you remove to drain the oil. Hope this helps.

Quite often this can be caused by low water supply. Check the filter that the supply hose plugs in to and make sure your water supply has plenty of pressure and volume. There will be a water volume rating in litres per min (lt/min) or (gal/hr) depending on what part of the world you live in. You need to have at least that amount plus half again feeding the machine under a reasonable pressure 6ft/lb Gravity fed from a tank won't cut it. If it is vibrating and hardly working there is grit stuck under one of the valves which isn't a biggie but if you don't know how to disassemble the pump valves take it to someone who does as there are small parts like springs etc that are easily lost. It won't break the bank to get someone to repair it. Cheers. Hope this helps.
