My dishwasher rinse temp is only at 110F. What would cause that?
SOURCE: hobart lx 18 warewasher what hatco booster heater product compatable with it
The answer to this question will be based on the incoming water temperature that is supplied to the booster heater. The standard sizing for a booster heater is based off of a 40 degree F rise (140 degree F incoming water temperature) or a 70 degree F rise (110 degree F incoming water temperature). For a 40 degree F rise, a Hatco model C-5, S-5, or PMG-60 will supply the needed amount of rinse water for the LX-18 Hobart dishwasher. A 70 degree F rise would require a Hatco model C-9, S-9, or PMG-60 to supply the same Hobart model number.
SOURCE: rinse not hot enough
145 degree is just your hot water temp and that your dishwasher hot water booster is not working assuming that this machine has worked in the past to produce final rinse water above 180 degrees. Remove the bottom panel and to the right you will see the booster tank, look for a nickel size component with a small red button on it. Try pushing on it to reset it. If that does not work, check for voltage at your heating element on your booster tank. (the thicker wires) If voltage is present then your heating elements need replacing.

The booster heat control circuit is controlled by the relay board. Visually check for loose or burnt relay contacts...
You will see the booster LED light when it calls for heat. Some newer machines have a second high limit on the right hand side of the booster tank.
It may be your control board is configured for low temp with no booster. When you power up, the display should say LX30H. If not
Pull open the upper drawer, place a magnet over the door interlock switch.
CAUTION, 220 volt power is present. be carefull what you touch.
on control board, short J5-1 and J5-2, then power up. You are in factory setup. press select on the control board to see each option on the front panel., press up arrow on control board to step up through options for each step. when done, press the off button on front panel. remove short and start up normally. With the magnet in place, AND THE DOOR CLOSED, run the machine and observe the relay board status lights.
If you want to adjust the temp set points, with the machine off, press and hold the hidden key behind the front panel logo, and press select on the control board.. Or on power up, hold the wask key..Same to adjust options as above. Press off to exit.
