Power washer capacitor question

Kealyboy

Hi I have a Aldi workzone power washer that is not working. Opened the front cover a tested power to switch which I have 230v turned switch on and am receiving 230v after switch. Power washer is not making any noise whatsoever. Motor is not running. There is a capacitor located after the witch on L&N wires. I’m thinking that the capacitor might need replacing. I do not have a like for like capacitor but I do have a a higher rated one off a oil boiler/burner motor.

Anyway is it safe to connect this capacitor just to test and see does the power washer work. See attached pic of existing power washer capacitor .

Thanks

can I test with this one

Hi, that's called a class X capacitor, it's a type of capacitor which is installed between L and N and suppresses RFI/EMI noise. The other type is a class Y capacitor, and that goes from L to E and another from N to E. Aa I said, they are only there for noise suppression, so taking it out of circuit for testing won't be an issue.

But the quick answer is that it's not the likely cause of a faulty pressure washer unless the washer is blowing the RCD, in which case it's likely that a class Y cap has gone closed-circuit and is creating leakage into earth.

the top one I took out of the power washer does this one kick start the motor. If this on was not working would the power washer still operate? Motor run

Well I can't see the circuit, but it clearly has X2 written on it and has a resistor across it - so I'm guessing it's a class X EMI suppression cap.
