Shorting a high uF cap directly is a bad idea. You can in fact ruin an otherwise good cap.
Also, worth noting the voltage rating on a cap. If it’s 50V say or less, it’s not that dangerous.
If you don’t have a 10W resistor, just use a bigger Ohm resistor and wait longer. What’s the big deal?
Lastly, why on earth is someone who doesn’t know how to measure or discharge a capacitor safely getting into the guts of an appliance?
