Question about Jet Tech Systems 24 in. F18DP Free-standing Dishwasher
Verify the contactor for working condition. maybe burned wires or bad contactor. if it is good then the rinse thermostat or, less likely, the booster element.

Mr Mark Evans is mistaken. In this model, there are two heaters, One for the rinse water (should go up to 85C, and 90C on some serial numbers) and one for keeping the wash water at 60C.
The fact that you're not getting proper rinse temperature maybe caused by a couple of factors. One, like mr Evans wrote, the controller or thermostat may need some adjustment. those are normally pre-set however they are adjustable. Might be able to gain a few more degrees. Two, water pressure may also play a role. to high water pressure will cause to cool down the booster too quickly and will vaporise your rinse water. water pressure should be at 25 PSI. On the other hand, any pressure below 20PSI will also give you poor results.
Mr Evans is right about waiting for the unit to have fully heathed up before the test is started.
If the unit is older than two years, I would check the washarm, make sure they are in good shape. Often a split at the bushing will cause loss of pressure. that is common to most Jet-Tech product.
And for last, if you have any mineral builtup in the unit, well this will cause all sort of problems.
On the F18, the gauges are not really acurate, often off by 10C. An external themometer is needed for acurate reading.
Hope this helps.
