I'm a Washington State 01 Master.
We brought in a temp company "certified journeyman", and he promptly wired a 208 1P commercial dishwasher to 480 3P.
Along with that, didn't bother to even energize correctly, and by the time him and the owner of the business heard the "pop", they had already let out all that most excellent magic smoke.
The unit is older, and some parts are not available.
Owner wants it fixed instead of replacement.
The transformer is one of the not available, it is 110 vac to 15 vac @ 45 va.
I took 2 doorbell transformers, 110 to 16@ 30 va.
Synchronized the windings and hooked up in parallel, then put an inline 3 amp fuse on the secondary so it wont overdrive the controls.
I'm getting 18v output. The control board is working, but not getting anything from the control pad.
I'm told the control pad was intermittent operation before.
I'm sure that difference is within the design tolerance to allow for the 10% utility fluctuation.
Just trying to get other opinions.
Thanks.
