Hobart AMXXS1300. It doesn't seem to be heating up, the temp goes to 78/60 Celsius then the 78 goes back down to 61 only to heat up again.. seems like its a non-stop cycle. normally takes 45mins to heat up, apprently thats not normal?? i found out that the machine has NEVER been filled with salt before previously since new, can this be the root to the problem?? what can i do now?

You are having a problem with the fill valve. If the unit fills AT ALL, with the power off, the fill valve is the issue.

It is a gold color valve behind the front kick panel. It has a large castle-like cap. Sometimes debris is the cause of your failure. (50/50). Turn off the water, and just take it apart slowly and pay attention to the plunger and spring. Take out the diaphram and screen, and clean it. There should be just one small hole in the diaphram. If cleaning doesn't help, you need to buy a rebuild kit. If you get the "ML" off the data plate, I can get you the kit P/N.

good luck

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: hobart lx30 E3 error

Error Code E3 relates to a problem with the fill. Specifically that the water level has not been recognized at the middle water sensor. This can be caused by a problem with the drain system as you describe, or by low water pressure to the machine (should be 15-25psi flow), or bad wire connection to this middle sensor.
Check for proper water pressure first (should be a gauge on the machine) during the fill. Then check / repair drain as needed. These will probably eliminate the problem

it has a time out function once float is up is your water pressure correct. if to low it will first few cycles be low but after the will get to correct level and that is to the top of grey plastic drain pipe it cannot or should not be higher then the Gray drain pipe top, it overflows out that any extra rinse goes down it. check the o-ring on bottom of that grey pipe you could be leaking out the drain in between loads you come back and half the water is gone.

This is what I found for the E4 code...hope this helps...and thanks for rating my effort...The Fang.


Machine won't fill or won't fill high enough(LX18, LX30 display shows "E0," "E2," "E3," or "E4")

1.Low water pressure — check for clogged hose strainer; check that site water pressure meets minimum flow pressures.
2.Make sure probes are clean.
3.No water pressure — main water supply valves may not be working.
4.Drain valve open - turn machine off to drain machine, then on. Repeat twice (this assists in clearing any drain valve obstructions). Wait for machine to reach READY mode and press WASH. Slowly open door several seconds later and note water level. Close door; 30 seconds later, open door slowly and check that water level is the same as it was. If not, repeat the
OFF-ON procedure.
5. Delime machine.
