EG-1 v1: Accidentally plugged 220v without changing voltage selector

Hi all,

Would like to have some advise that I've accidentally plugged my EG-1 grinder into the socket of 220v without changing the PSU's voltage selector (still 110v). There was loud pop sound and I turned it off immediately.

Could I just blown the fuse ?

Edit: It's EG-1 v1, so it comes with a controller box

Does it not run now? Unfortunately you probably blew the controller. $500 plus (for me) $37 shipping. Sadly, I know what I'm talking about. I forgot to ask, is this the V1 or V2? My reply was the cost to replace the original external controller. If it was the newer version you should contact Doug at WW and follow his advice.

Pity these things aren't Universal Voltage like so many other electronic devices. Just attach the proper plug adaptor to fit the wall socket outlet and plug it in. Nothing else required.

Fuses fail silently so the lout pop is a sign that something else was damaged / blew.

Wayne, if you can find a good electronics technician or an old-time ham radio operator in KK, I'd open the box and see if a board level repair can be done. I don't know the circuitry of your machine, but with ham radio power supplies, when an over voltage or bad transient happens, often it's merely a fuse, bridge rectifier or voltage regulator that gets fried. Rectifier bridges and regulators often fail with a pop. You've got little to lose in attempting a board level repair and by the sound of things from the other reply, at least $500 to save.

Just to be clear, my damaged EG1 was the first version that had a separate third party supplied controller, that either had to be replaced or repaired by the third party supplier. The new version EG1 is 100% Weber. And can be repaired by WW or at the very least be given the best advice on how to repair.

My advice: ask a moderator to erase this topic, contact Weber and tell them your grinder does not work anymore :mrgreen:

+1 for Nunas!

MOVs that protect for over voltage spikes also blow with an explosive pop.
I would look for a well experienced computer shop that can repair switching power supplies.
I doubt the whole thing blew front to back. It probably is an MOV or bridge rectifier or maybe even a (electrolytic) capacitor.

Right Maurice? :mrgreen:

when I blew my EG1 controller, no computer, stereo repair, or electric motor repair specialists wanted anything to do with it. The best advice is the the poster who advised contacting WW.
