    What does “on the one side” mean?

     

    What are the fuses for?

    I haven’t a clue where your fuses are geographically.  If you say they’re “on the one side”, I’ve nothing to verify or contradict that.

     

    From the unit’s schematic, I DO see where fuses are ELECTRICALLY.  According to the schematic, there are three fuses – one for each input line to the contactor feeding the heating elements.  Within this manual is a schematic.  Probably the same schematic that’s affixed to a panel within the machine’s control box:

    http://download.partstown.com/is-bin/intershop.static/WFS/Reedy-PartsTown-Site/-/en_US/manuals/CHA-KB_spm.pdf 

     

    So the fuses blow every two weeks?  ALL of them…or just one here and, two weeks later, another one?

     

    You said the “elements check out okay.”  So you’ve verified that they have proper resistance, proper input voltage, proper amp draw and no indication of insulation breakdown as tested using a voltmeter, ohmmeter, ammeter and a meg-ohmmeter?

     

    If that’s the case, then I’d suspect a poor fuseblock connection causing the fuse to get hot under an electrical load and opening.  That can quickly be revealed by doing some strategic voltage drop tests across the fuseblock…or by getting a temperature sample of the connections while under load through the use of an IR thermometer or a thermal imaging camera.  Any one of those three devices will certainly reveal a faulty fuseholder connection.

     

    If you have NONE of these items of test equipment or the knowledge of how to use them, then you need to call a service company to diagnose your problem.

    Are you referring to the block behind the right post and swing door or the one on the swing panel? Or the transformer block.

    I took a geography lesson.

     

    Here’s the fuse locations.  Tank heating element fuses circled in GREEN.  Transformer fuses circled in RED:

    I have the same problem with my STPCW-30 dishwasher from Stero.

     

    Don’t ask me about it, because If I get started I can’t stop. All I am going to do is share 2 thermal pictures of the fuses .

    Oh, and let me guess. The control transformer drops the voltage down to 120V from 208 or 240?

    Thank you for all the input. After tearing into the unit I discovered that from the lack of maintenance, the 1 element (3 elements in one) was so encased in residue that it was either shorting out or over heating. After a thorough cleaning …problem solved.

    Makes sense, the booster is right behind the fuse block. Bet you had a good time getting all the minerals  out.
