Why is my hobart am 15 not getting to wash temp or rinse temp

Most likely sump temperature probe needs replacing.

Your rinse temperature sensor that is a tiny probe in the water piping (top rear of machine) needs replaced. Hobart part # 00-294692. It costs about $84.

The WM-1D does not have any internal heating devices. You have to supply the machine with the proper water temp. It has two fill valves, one for wash and one for rinse. It should have 150F supplied to the wash fill valve and 180F to the rinse fill valve.

A hobart LXIH-3 uses a chemical to sanitize however a 120 degree wash temp is required as well.

Turn up your hot water tank that supplies the dishmachine, make sure your sanitizer is pumping into the rinse cycle using micro-clorine test papers and all is well.

First off, the temp adjustment can only be made by a trained service tech, since the dishwasher will need to be reprogrammed to allow for a lower temperature in the rinse cycle but still have the higher temp needed in the wash cycle. Also, since any change in the water temp settings will require a longer wash and rinse cycle to be programmed into the unit.

Of course, you could simply lower the water temp on the water heater that supplies water to this unit, but you'd have lower temp water elsewhere and likely get cited at the next heatlh department inspection on that issue.

Since this is a commercial dishwasher, you might want to reconsider lowering the temp, since health codes and standards for commercial establishments require a MINIMUM water temperarture of 185 degrees F (85 degrees C) for proper operation and to get all the crud off the dishes, etc.

Note, the manufacturer sets these units to the higher temp, 203 degree F (95 degree C) knowing that the water will cool down quickly once the wash cycle starts and the water contacts the dishes, etc. That is also why these units have a added heater element, to help keep the water at the correct temperature needed to both clean AND sanitize the dishes, according to established health standards.

If you really want to change the water temp settings, contact your Hobart service rep and explain the reason you want it lower and see what they say.

Hope you found this very helpful and best regards!

If it is new, would you not call Hobart for a warranty call? 1-800-444-4764 to reach the nearest branch in Canada.
Seeing it's new it is most probably not programmed correctly. On the control board is factory jumper J5, short thse two pins and press ON on keyboard. when the display shows ty remove short. pressing select on the CB will change the options, pressing up arrow will incriment the change options. first setting is machine type= AS,second is id, hot/cold or plain AM15 only, select H,C,or P.
3rd is tc,auto temp control. The rest will not affect your condition. Press OFF on keyboard to save and exit.

When the unit is idle and in a wash cycle the wash temp is displayed.If you look inside the tank you will see a white float and a metal probe which is the themometer for the wash tank temp.The rinse temp will only be shown when the display reads (Rinse) and theres a thermistor that screws into the water line near the solenoid valve that measures the temp.

check to see if your element is scaled up or your element may be damaged

This unit is a sanitizer, not a full fledged dishwasher. It is designed for restaurants and bars where the primary use is washing glassware. The behavior you describe is normal for this model. The manual can be found at the following link:
