After 20 mins water temp still not at 150 on my jet-tech 737 dushwasher.

Check the inlet screen to the water circulating pump and the water heater element for lime buildup. I've seen a heater element that had a 1/4" thick layer of lime encasing it. The inlet also had some lime and other debris clogging the screen. After carefully chipping away as much as was practical and running lime remover (such as CLR) through the machine, it heated the water much more quickly and had an effective spray.

To prevent a recurrence of this problem, make sure you have a functional water softener ahead of the water heater feeding the machine.

If it’s brand new, return it or get warranty service

If the machine will fill on its own when it is empty then the rinse cam on the timer is defective

How do I find those wire in the machine?

that happened to my e tech 150, water seperator and paperless filters fixed mine

ki can get them for you e mail me at [email protected]

The 737 model could run on even lower temperature (80F). Given time, the unit will heat up the water. the trick is to give it time.

That model is made for commercial use, not really for residential. It will not fully drain every cycles. The important thing to keep in mind is to empty the dishwasher (turn it off, pull the stand-pipe out, and drain) every night and left empty. When you want to use the unit, put the plug back in and turn it on, wait 20 to 30 minutes and it should be ready.

Ouch.

Before you start changing all sort of parts, correct your problem with the wires. You may have to change most of them, depending on how bad the chemical burned tru them.

A good cleaning is required because that soap is going to continue chewing on those wires.

You're right about a short causing other component failure. But first repair those wires
