Smart drive 058 won’t start

[ohno]

When I power up my Smart Drive 058 no leds light up. I faintly hear a repetive high pitched whistle like a switch mode power supply trying to start but maybe loaded down by something? Any ideas where to start?

Ohno

Are there any lights at all coming up when washer powered up ?

If not Could be 2 Things

1/Motor Controller
2/Pump On this model power runs thru drain pump if Pump is faulty then
washer will not power up

[ohno]

Re: Smart drive 058 won’t start

Thanks for the quick reply. No lights come up at all.

Ohno

Best case then would be pump faulty

But more than likely M/C

[ohno]

Re: Smart drive 058 won’t start

So the pump may be open circuit I guess?

If it turns out to be the motor controller, what are the common faults? I suppose the FET’s would be most likely to blow.

[ohno]

Re: Smart drive 058 won’t start

The pump measures 33 ohms with no leakage to ground so I guess that’s fairly normal.

Pump correct reading

[ohno]

Re: Smart drive 058 won’t start

Thanks for the confirmation of the pump resistance. Is there a circuit available for the motor controller anywhere?
