Hi,

Initially would suggest to check that the power supply requirements are satisfied. You might also need to check the breakers. Depending on the exact model number, the AC supply can be as shown below:
I have a hobart lx-g - bb8887d.jpg
If the above checks out OK, then it could be as you have suspected, the controller is messed up, more specifically the firmware or related electronics. You could of course try a reset by unplugging from the mains or switching off the appropriate breakers for say half an hour.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

F the dishwasher's water flow doesn't automatically shut off, the float switch is faulty, the timer is stuck on "Fill," or the water inlet valve is stuck open. To test the float switch, you'll need an inexpensive volt-ohm meter (or multi-tester).




1) Unplug the dishwasher.
2) Reach into the cabinet, and lift the dome-shaped plastic float switch. If it doesn't lift, remove the plastic top from the stem, scrub the stem clean, and then replace the dome. If it moves up and down freely, go on to Step 3.
3) Note which wires are attached to the float switch's terminals, and, using small pieces of tape, label them for later reference.
4) Set the volt-ohm meter's dial to Rx100 and touch the two probes to the terminals. When you lift the float, the tester's needle should show an infinity reading, and, when you let the float drop, the needle should show 0.

If it doesn't, the switch is broken and will need replacement. Unscrew it from the tub, and replace it.

Hope this helps

Here is what i got from Hobart...

Machine won't fill or does not fill completely.
(Display shows E0, E2, E3, working.
or E4. Machine will not 4. Drain valve open — turn machine OFF to drain machine, then
run.)

1. Low water pressure — check for clogged hose strainer; check that site water pressure meets minimum flow pressures.
2. Make sure probes are clean. (Refer to Cleaning, page 12.)
3. No water pressure — main water supply valves may not be 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. If problem contact Service.
5. Delime machine.

hope this helps out. if you have other questions just let me know

Need bushing for sprayarm and repair manual


The wash arm bushing for this model is not available separately. You can use the bushing from the LX series and cut it shorter to length. Hobart will not issue service manuals to non Hobart personel because of liability issues. If you injured yourself from misinterpreting the manual, they would apparently be resonsnsible.

Hobart LX 30 undercounter dishwasher, commercial Does this model require booster?


Most of the Hobart LX series of dishwashers have their own built-in booster heaters. To check for one, remove the lower front panel (2 screws). The booster heater, if present, will be a stainless steel tank on the left side. If it doesn't have a built in booster heater then it was meant to be used with chemical sanitizer instead.

Hi James, This may sound a bit odd but... if you really want to make sure all of the water is out of the unit just remove the drain hose and use a shop vac to draw out all the residual water. Then just place about 1 to 1.5 cups of vegetable oil in the sump for the winter. I do not recommend anti-freeze due to the associated health reasons of same. Then next season remove the drain hose and draw out the vegetable oil before returning it to regular service. This works well for resorts in cold climates. The vegetable oil can over several seasons fatten up or harden pump seals but is no more harmful than the anti-freeze on the seals.

Thanks for choosing FixYa,

Your best option is to contact a used appliance dealer and hope for the best on locating racks.
I priced some similar model racks for a customer 2 months ago. They were over $400 each.

Hobart LX 30H shuts off and turns back on by itself


Hello Jon,

I work in the product service department for Hobart Corp. and work mainly with the Hobart dishwashers. The most common problem with what you have going on is a faulty keypad on the front of the unit. This is the component with the actual on/off/wash buttons on it. If the problem is very frequent, then you could contact your local Hobart service office and they could come out and troubleshoot the problem to be certain that this is the faulty part before just buying a part and hoping that it works. If you would like to discuss this a bit further or need assistance as to a contact for your local Hobart office, you can contact us at 937-332-2525, and press option #2.

Have a great day!

Jim

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.

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.
