Maytag dishwasher blowing fuse

I can get the model number later today...

I'm cosidering the Master Samurai Tech course bundle, but I'm frustrated that I can't figure out this problem with my dishwasher.  The thermal fuse on the control board failed, and I replaced it.  It failed again on first use, toward the end of the wash (not sure exactly what cycle it was in).  I pulled the schematic and checked the heater...and found it's within spec for resistance.  Thoughts?  I'm a beginner and very interested in pursuing a second career in appliance repair.

Was this a thermal fuse that came with a wiring harness in the kit and by any chance did you just replace the fuse and not the harness.

No instructions come with newer packaged Whirlpool/Maytag parts, you have to go to the web site that is printed on the plastic package the part came in and enter the part number of the part to get the instruction sheets now.

You have to replace the wiring and the fuse, if you don't you will have continuing problems.

I'm considering the Master Samurai Tech course bundle

I suggest that you do.  The best investment in the world is you and knowledge is the best tool in any toolbox.  Think about it this way, if add up all the time that you spent on calls  where you had an issue or did not know how to troubleshoot it proficiently , and put it into training and educating yourself about them your day would go way easier.  There is a lot to know these days, the machines have become more complicated and require a better understanding of the operation than ever before.  You are on the right track you found this site.  Some of these guys will blow your mind with how much they know, in addition to training, you have them as well.

Thank you, Willie.  I did follow the instructions and installed the new wires that came with the fuse ( I didn't do that the first time).  So the fuse blows somewhere toward the end of the wash, as the dishes are pretty clean, but with a good amount of water left in the tub.  As I said, I'm very much a beginner in this.  Any suggestions on other parts to check resistance of?  I did pull the schematic but I'm not well versed in reading them yet.

Gags730,  I'm not a tech at this time.  It is something I'm considering, as I'll be wrapping up my current law enforcement career in about a year.  I was recently inspired to look into appliance repair after my local appliance repair guy came to my house (for the dishwasher) and I realized pretty quick that he's just a parts changer.  Also, he's the only game in town and he claims to be extremely busy.  Clearly there's a need for another tech in town.  I like the look of the Master Samurai Tech program, but I'm a bit concerned about the hands-on aspect of the job, if I don't have experience there.  Thanks for your input, I'm probably going to start the course after the holidays.

Sean.

A fault/failure that is not uncommon.

If you post the Model/Serial numbers...one the techs on this forum will likely provide a service bulletin that addresses this problem.

Here is the model #

Maytag
