Not heating up to temp of 150 for wash cycle - Jet Tech Systems 24 in. 737 Free-standing Dishwasher

Did you check behind the toe-kick panel for the tech data sheet? Assuming that you have checked and that it is missing, there here is the "secret keystrokes" that will make most Whirlpool/ KitchenAid/Kenmore/Maytag diswashers enter the diagnostic cycle:
Heated Dry - Normal - Heated Dry - Normal; or
High Temp - Air Dry - High Temp - Air Dry; or
Hi Temp Scrub, Energy Saver Dry, Hi Temp Scrub, Energy Saver Dry; or
High Temp Wash, Heated Dry, High Temp Wash, Heated Dry.

Note: On some of the newer Whirlpool, Kenmore, KitchenAid dishwashers, you start the diagnostic cycle by rapidly pressing the 3 left-most keys in the following sequence: 1 2 3, 1 2 3, 1 2 3.

Most dishwashers require a minimum 120 degree inlet water temp. The heating element will boost this up during the main wash cycle to aprox 140. Do not hook a dishwasher up to inlet water temps above 150.

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.

F05 is a water temp sensor error ,could be a bad heating element, or the temp sensor may be faulty, try checking the connection's to the temp sensor and heating element, also check the element relay.

How hot is the wash temp?It should be 150-165 degrees.The model is an am14 not an am15?I'm hobart tech and repair these units weekly.Let ne know.

Somewhat,

I have a ref. thermometer, round metal type I got a Wal-Mart that I check the dryer temp at the discharge. I bent the metal bottom so I can lodge it in the discharge pipe, turn the dryer on and watch the temp. Normally on high heat it will go up to 140-150 and cool down to 120-125 then cycle back on.

press (high temp-wash) button and then ( heated dry)
do that 3 times in that order within 5 seconds. So it looks like this:

(high temp-wash) ( heated dry) (high temp-wash) ( heated dry) (high temp-wash) ( heated dry)

That will start a short diagnostic cycle (last about 2 minutes) that will clear the blinking light and allow you to use the dishwasher. If the light comes back, your drying cycle has failed and you will need service.

Most DW today take a minimum of 90 minutes. Run the hot water from the sink until it gets hot, then start the DW, this will shorted the first wash cycle. It is not uncommon for the DW to run 2hrs or more based upon the water temperature entering the DW and the soil level of the items in the DW.

a ten degree drop isnt bad,what is the problem?

Puppa, clear the fault by pressing the keys in this order: high temp scrb--air dry--high temp scrub--air dry. Or, depending on your model..Sani rinse--air dry--sani rinse--air dry. The dishwasher will enter the service mode. Let it do it's thing or advance it through it by pressing the start key. The fault came from the board not sensing a rise in the water temp. Make sure to run the hot water before starting the dishwasher. The heating element runs through the nuetral side of the door switch so make sure the d/w is level and the door switches are all making. The element itself could be at fault. Catriver...post back
