SWMBO's Steam Cleaner

What's the component I'm holding, any ideas? No markings. No continuity on the outgoing red. Cheers.

A line suppressor, used on many universal motors to stop radio interference. In other words a capacitor network.

smash it open and find out

It's not made by Ford, anyway :D

It appears to be in line with a solenoid(?) Most likely a suppressor as suggested, or it just MIGHT be a rectifier. If it's dead anyway the suggestion to cut it open is sensible.

Looks to me like potted built in obsolescence, smash it open and see if you can replace whatever is smothered in the potting compound.

It's a capacitor/diode arrangement to stop interference and back emf when the solenoid opens and closes, it will run without it, worst case scenario it may cause interference with the radio or tv when it switches, a bit like in the good old days. lol

I'd go with it being an MOV to quench the back emf from the ac powered solenoid being de-energised so it can't get back into the mains supply and to the other parts in the device.

Yes I know it's an old thread...

 

Just dug SWMBOs old Morphy Richard's steam cleaner out of the "must fix one day" pile.

 

I did indeed take a hammer to the encapsulated, duff component as suggested.

 

- 2 small electrolytics. Values readable.

- 1 resistor. No markings.

- 1 semiconductor. No markings.

 

R1 is open circuit.

 

Q2, (couldn't figure why if a simple passive RC thing) is missing half the case (sifting the sweeping off the patio still but I think I need to widen the search area! 😂 )

"ET-CF02" isn't bringing anything up. Tried tagging it with EMF, choke, suppressor, filter etc.

 

I thought I'd take the rest of the encapsulation off the back of the board and draw up the little "4 component" circuit. Maybe not!

Active filter is it?

Well I try to fix most things, with mixed success, but I wouldn't fancy chances with that.  That's much more than a suppressor.

It looks to me that the designer has involved electronics in the design; (this seems almost mandatory these days, after all why use a switch if you can get a microprocessor and triac involved?)

I would guess, without seeing the track layout,  that the resistor and capacitor will be to provide a low voltage supply to the electronics. If so there will be  a diode and a Zener diode too.

230V goes into it and should come out and go straight to the 230V solenoid. So a capacitor network/suppressor but WTGrape so complicated? Yes, I can bypass easily enough and see what happens.
