Hobart am 14 makes a grinding noise before rinse cycle

SOURCE: hobart am-14

facing front of machine top right near pressure guage there is an electric solenoide valve , you must change the kit inside it is eighter diaphram type or piston type, you must shut off the water inlet before servicing, then undu the 4 bolts on the top of the valve to see if it is diaphram or piston

The rinse water in a LX30 is driven by water pressure. A solenoid valve, bottom front - gold body, opens up and allows the water to flow.

If you are referring to the rinse agent pump, there must be NO leaks in the tubing or the hose that runs through the pump. And if the unit has lost its prime, using your hand to "seal" it, and forcing water from the faucet into the line can prime it.

Good luck - Mike

Did the clean light indicator blinking over n over? check the element wire harness connector. If disconnected fix it and run your dishwasher again.

Also you may check the continuity of your heating element.

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.

SOURCE: No water pressure in rinse cycle

AM 14's need 20 PSI flow rate of rinse. Is your pressure gauge accurate? Could the rinse nozzles be blocked with scale? If you remove them to clean, make sure they go back in the same positions. Note the upper arm has one each side pointing up, to clean the top of the machine. Check that the upper rinse arm has it's thrust washer under it's hub.
